When you’re considering applying for a mortgage, one of your top questions is probably “What is the monthly payment going to be?”

For a 100K mortgage, the payment on a 30-year loan at 7% interest would be $665.30. For a 15-year mortgage loan term, the payment increases to $898.83, which helps you pay off the loan sooner and pay less in interest costs over the entire loan.

Your own loan will depend on a number of factors, including but not limited to fluctuating interest rates. Here’s what goes into a 100K mortgage, what income is required to get one, and what your payments would look like over the life of the loan.

Total Cost of a 100K Mortgage

The total cost of a 100K mortgage goes beyond the monthly payment. There are upfront costs and ongoing, long-term costs to consider, all of which affect how much house can you afford.

Upfront Costs

Upfront home loan costs can include:

•   Closing Costs: There are costs you need to pay to get a mortgage, but they are not a part of the original loan. These are known as closing costs and include things like the mortgage origination fee, the cost of an appraisal, attorney fees, title fees, taxes, prepaids, and other expenses. With the average closing cost on a new home adding between 3% and 6%, that works out to $3,000 to $6,000 on a 100K mortgage.

•   Down Payment: Unless you are able to obtain a 0% down payment loan, you’ll need some money to afford the down payment on a 100K mortgage loan.

The average down payment on a home is 13%, as per the National Association of Realtors®. This works out to $13,000 on a $100,000 home.

If you don’t quite have this amount, there are other types of mortgage loans that offer low down payment options. 3% and 3.5% are common, which would come out to $3,000 and $3,500 for the down payment on a 100K home.

Long Term Costs

Here are the ongoing costs of a mortgage loan:

•   Interest. The biggest expense you’ll have over the life of the loan is interest. Interest costs are huge, especially in an economy with higher annual percentage rates (APRs). You’ll pay more in interest than you do in principal if you keep the mortgage loan for the whole 30-year loan term.

For a $100K mortgage with a 30-year term and 7% APR, the interest costs total $139,508.90.That’s on top of the $100,000 original loan amount. Adding the two together, you’re looking at paying $239,508.90 for the original 100K mortgage. Take a look at our mortgage payment calculator or the amortization table further down if you’re more curious about this amount.

•   Escrow. You may pay for taxes and insurance through your escrow account every month. This expense doesn’t go away, even when you pay off your mortgage. The amount of tax and insurance varies by state and policy.

Estimated Monthly Payments of a 100K Mortgage

Payments on a 100K home will ultimately be determined by your loan term and interest rate. And the interest rate is determined by a number of factors. Of course, the Fed’s rate matters, but so too do such aspects as:

•   Credit score. A good credit score can afford you a lower interest rate on your mortgage.

•   Down payment. Generally, putting down a larger down payment affords you a lower interest rate.

•   Home location. There are certain areas where you may be offered a lower interest rate just because of where you live.

•   Loan amount. If you need a larger loan, such as a jumbo loan, you’ll usually see a higher interest rate. The same can be true of much smaller homes, such as tiny homes.

•   Interest rate type. If you choose a loan with an adjustable APR, you may initially have a lower interest rate.

•   Loan type. You’ll see different interest rates based on what loan type you’re using. Examples include VA loans, FHA loans, and a USDA loan which may offer a lower (or no) down payment as well as lower interest rates.

•   Loan term. Choosing a mortgage term that’s shorter can help you score a lower interest rate.

Monthly Payment Breakdown by APR and Term

It’s helpful to see what potential mortgage loan payments on a 100K mortgage may be, adjusting for term length and APR variance. Keep in mind these costs do not include escrow items, such as taxes or insurance.

How Much Interest Is Accrued on a 100K Mortgage?

Each month, your payment is split into principal and interest payments. Those interest payments go to the bank as payment for lending you money. Principal payments go toward the original loan amount and pay down the loan.

The longer the loan term, the more you’ll pay in overall interest. For a 100K mortgage on a 30-year term with a 7% APR, the interest costs total $139,508.90 on top of the original loan.

On a 15-year term with the same parameters, the interest costs are a more modest $61,789.09. Yes, your monthly payments are higher, but the difference between a 15 vs. 30 year mortgage with 7% APR is significant.

100K Mortgage Amortization Breakdown

The amortization of a 100K mortgage shows how much of your monthly payment pays off the loan each month.

You can see in the early years of your mortgage, more of your monthly payment goes toward interest, and very little of your loan is paid off. In later years, more of the payment will go toward the principal.

What Is Required to Get a 100K Mortgage?

When you’re applying to qualify for a mortgage, lenders look for a few key things to approve your application.

•   How much debt you will be carrying. Lenders look for your monthly payment to be lower than 28% of your gross monthly income. A 100K mortgage payment at 7% interest on a 30-year term is $665.30. For this payment to be less than 28% of your monthly income, your monthly income needs to be over $2,376, assuming you have no debt. This turns into a $28,512 yearly salary requirement to afford a 100K mortgage payment.

If you have debt, the calculation changes a little bit. Your lender will add your monthly debts to your projected monthly mortgage payment. These two numbers added together need to be less than 36% of your monthly income. This calculation a lender does is known as the debt-to-income ratio, or back-end ratio.

“If you have multiple debts, you want to make your minimum payments so you don’t hurt your credit score,” Kendall Meade, a Certified Financial Planner at SoFi said. “If you have cash left over after that, you should develop a strategy for which debts to pay off first,” she suggested.

•   Credit score. It’s advisable to have a credit score of 620 or higher when applying for a mortgage loan.

•   Consistent work history. If you are unemployed, self-employed, or have recently changed jobs, lenders may be less likely to approve your loan. They may worry about your having a steady enough income to make your payments.

The Takeaway

A 100K mortgage will have a monthly cost that varies depending on such factors as the loan’s interest rate, the term of the loan, and whether it’s a fixed- or variable-rate loan.

Working with a professional real estate agent can make buying or selling a home easier. After all, they are likely to be well versed in the ins and outs of your area, how to best negotiate in the current market, and how to access any other resources (say, a home inspector) that you may need.

Working with a professional real estate agent can make buying or selling a home easier. After all, they are likely to be well versed in the ins and outs of your area, how to best negotiate in the current market, and how to access any other resources (say, a home inspector) that you may need.

While there may be some agents you hit it off with personally, this isn’t a friendship you’re pursuing but an important business relationship. It’s a collaboration that could impact both your finances and your stress level.

No matter which side of a real estate transaction you’re on (buying or selling), it can be wise to have the right professional in your corner. Eighty-nine percent of homes sold in the U.S. involve an agent or a Realtor®, according to a 2023 report. (Realtors are agents who belong to the National Association of Realtors, or NAR.)

If you’re on the hunt for an agent, it’s important to know what to ask to identify the right match. Read on to learn questions to ask, whether you’re buying or selling a property — or doing both at once. (This is a lengthy list of interview questions for real estate, so pick and choose the questions that resonate the most.)

How to Interview a Realtor

First, a bit about terminology: Not all real estate agents are Realtors, but for the purposes of this article, we’ll sometimes use the two terms interchangeably.

There are different options for interviewing Realtors. You could schedule an interview:

•   Over the phone

•   In person

•   Virtually via Zoom or Skype.

You might aim to interview at least three agents for comparison’s sake, though you may choose to interview more or fewer.

Create a list of interview questions beforehand to help you stay on track, and begin researching a home loan so you will have a sense of your budget. By the time the interview process is over, you should understand:

•   What the agent’s personality and character are like: Is this person supportive and positive? Do they sound rushed and distracted?

•   What kind of services they offer and what experience they bring to the table.

•   How much you’ll pay for their help.

You’ll learn about how to do this in more depth as you read on.

What to Ask About a Realtor’s Background

Any real estate agent you choose to work with should have the professional qualifications you’re looking for. But it’s also important to get a sense of who they are as an individual to avoid personality clashes. Here are some questions to ask as you evaluate an agent who might help you buy or sell a home.

1. How Long Have You Been a Realtor?

It helps to understand how long an agent you’re considering working with has been buying or selling homes. The median real estate experience of all Realtors is eight years, according to NAR.

Working with an agent who’s newer to the profession isn’t necessarily a bad thing. But one who’s more experienced may be more adept at handling any challenges that arise when buying or selling a home.

2. How Well Do You Know the Local Market?

A Realtor who knows a particular area and its local housing market trends can offer an advantage when buying or selling. Ideally, you should work with an agent who understands the local market and what trends drive it.

The more informed they are, the better equipped they are to do things like comparative market analysis, which can give you a sense of how home prices in the area are trending. They will also likely know details like, say, which parts of town are more prone to flooding than others.

3. How Many Clients Do You Work With at One Time?

The answer can give you an idea of how much time an agent will be able to dedicate to working with you. Especially if you ask the follow-up question, “And how many clients do you currently have?”

4. Do You Work Alone or as Part of a Team?

Keep in mind that you may not be working with your Realtor alone to finalize the purchase or sale of a home. Agents may have a team of individuals they work with, including office managers, personal assistants, or marketing directors, who may reach out to you during the process.

Asking who else you may be connected with can help you avoid surprises if you decide to enter into a working relationship with a particular agent.

5. How Will We Communicate and How Often?

Being able to communicate with an agent is important to keep the process moving. Plenty of Realtors email and text to keep in touch with clients. If you’re the kind of person who prefers phone calls or in-person meetings, it’s good to identify communication styles up front and make sure they are in sync.

6. Do You Specialize in Buying or Selling?

Some real estate agents may choose to work exclusively with buyers, while others work only with sellers. And some can act as dual agents, representing both the buyer and seller in the same transaction. Dual agency is rare, and it’s illegal in several states. A dual agent can’t take sides or give advice.

The answer to this question will help you get a better idea of whether the agent is attuned to your side of a real estate transaction. Ideally, you want someone who is passionate about your deal, whether that’s finding the perfect house with a picket fence or selling the condo you’ve outgrown.

7. How Many Transactions Did You Close Last Year?

Asking this question can give you an idea of an agent’s overall success rate and the volume of transactions they handle.

The median number of residential transactions Realtors took part in per year in 2023 is 10. If you’re interviewing agents with closings well below that number, it could be a sign that they aren’t always successful in closing deals. If their number is much higher, it could mean they are super busy and you might not get as much attention as with another agent.

8. How Long Does It Normally Take You to Close a Deal?

Once the seller and the buyer of a property have signed their purchase agreement, closing on a home can take anywhere from a week (for an all-cash offer) to a couple of months (for those involving a mortgage) to close. As of mid-2024, the average closing time on a house was 43 days after an offer was accepted, reports ICE Mortgage Technology, Inc.

Asking a Realtor what their average closing time is can give you an idea of how efficiently and diligently they work to satisfy their clients.

If their average closing time is closer to four or six months, for example, that could be a red flag, though some deals do wind up being more complicated than others.

9. What Are the Terms of Your Contract?

Working with a Realtor means entering into a contract, and it’s important to know what that contract says. These documents may be more common when you work with a broker to sell a home, but there are also buyer’s agreements.

These ensure that if they invest the time scanning the market for you, scheduling walk-throughs, and negotiating on your behalf, you won’t then complete the deal with, say, a relative of yours who just got their real-estate license.

When you are selling a house, you’ll sign a document agreeing that the agent will handle the sale. Once you sign a contract you’re typically locked in to working with them unless they agree to release you.

The listing agreement will last for a set period, such as three or six months. From your perspective, shorter may be better so that you’re not trapped if you don’t like the agent’s services.

10. What Fees Do You Charge?

Closely connected to contracts is the topic of money. How does it change hands? What are you liable for? Historically, real estate agents worked on commission, and the fee was paid by the seller. Now, real estate commission fees are changing, and while sellers will still likely pay agents a commission, there is no guarantee that the seller will pay the buyer’s agent. If you’re buying, you’ll need to discuss a fee structure with an agent before you begin working together. It might be an hourly fee, or perhaps a flat rate. Some agents may request a percentage of the home price.

Questions to Ask a Realtor When You Are Selling

If you’re selling your home, here are some questions to ask to help ensure that you partner with the right agent.

11. What’s Your Typical Marketing Strategy?

A real estate agent should have a clear plan for listing and marketing your home in a way that produces the greatest odds of success in selling it quickly and at your desired price point. Let the agent you are interviewing tell you about their strategy and the results it yields.

For instance, does the Realtor believe in listing at a low price in the hopes of starting a bidding war? If so, what kinds of prices has this achieved? Where will your listing be posted? Will videos be created? Will there be an open house?

These kinds of questions can help you see if you are impressed by and aligned with how a Realtor likes to market homes.

12. Will You Handle Staging and Prep Work?

If you’re selling a home, staging it could help influence buyers’ perceptions of the property and potentially net you a higher sale price.

Staging is something you can do yourself, but your Realtor may have a staging company they work with to get the job done.

Asking about staging or small cosmetic updates, such as painting, can help you figure out what you’ll be responsible for to get your home ready for the market. There’s a price tag attached to all improvements, so you’ll want to know the numbers to be better prepared.

13. How Do You Handle Viewings?

The use of digital tools such as virtual tours have made properties more accessible to more buyers. One survey by Zillow found that almost 40% of Millenials would be comfortable buying a home online vs. in person.

See if your agent plans to create a virtual tour, but you also want to be prepared for the majority of buyers who want to visit in person. Ask Realtors how many viewings they typically schedule in a day or a week, how often open houses will be scheduled, and how they’ll be marketed.

Questions to Ask a Realtor When You Are Buying

Now you’ve learned the questions to ask a Realtor when selling. How about the other side of the deal? Whether you’re shopping for a starter home or trading up, here are a couple of important questions to ask a potential real estate agent when preparing to buy a house.

14. What Happens When I’m Ready to Make an Offer?

If you’re a buyer, agents should be able to walk you through how this process works, what to do if the seller makes a counteroffer, and what you’ll need to do next if your offer is accepted. You also want to check if they have experience with successfully navigating bidding wars, which can happen in hot markets and with well-priced properties.

Also check that they can advise you on how much earnest money you might need to pay and how to find a good, affordable home inspector, as these are important aspects of the homebuying process.

15. Will You Help Me With Getting a Mortgage?

This question will shed more light on a prospective agent’s network and experience. Agents may be able to offer recommendations for mortgage lenders. They may also be willing to communicate with your lender if there are questions about the property or the offer during underwriting.

You’re not obligated to use your Realtor’s recommended lender. In fact, it’s helpful to compare mortgage loan terms and interest rates from multiple lenders to find the option that best fits your needs.

The Takeaway

Due diligence in the search for the right real estate agent may mean interviewing a few of them and not automatically going with a friend of a friend. It’s important to know how to interview a Realtor and which questions to ask, so you can pair up with the best possible professional as you navigate this major transaction.

If you’re a buyer, once you’ve found an agent, you can turn your attention to next steps: finding a home (and a home loan) that suits your needs.

FAQ

What are the benefits of using a real estate agent to buy a house?

Having an agent to survey the available properties and recommend the ones that suit your needs could certainly save you time, and agents often have local market expertise and the inside scoop on properties that might be headed to market. An agent should also be well versed in the negotiation process (especially useful in a seller’s market) and able to help coordinate the many moving parts that lead to a closing.

What should a homebuyer do before talking to a real estate agent?

It’s wise to have an idea of your budget before consulting a real estate agent. You can prequalify for a mortgage with a few lenders to get a sense of what you might be able to borrow. Also do research online about your desired town or neighborhood to get a sense of where you would like to live. And know your non-negotiables — minimum number of bedrooms, whether you prefer an old home or new construction, for example.

SOHL-Q324-054

For most Americans, mortgages are a necessary part of life. Without them, we couldn’t afford the homes where we start a life and perhaps a family. To pay for that cost, you likely need a mortgage.

However, the cost of a mortgage goes well beyond the amount of the loan. There are both upfront and ongoing costs that will be a factor in the cost of the mortgage. In this article, we will look closer at a $400,000 mortgage and what the monthly cost might look like.

Total Cost of a $400K Mortgage

To determine the total cost of a $400,000 mortgage, we must consider more than just the $400K price tag. Upfront and ongoing costs are involved, which are factors in what you ultimately pay.

💡 Quick Tip: SoFi’s Lock and Look ⁺ feature allows you to lock in a low mortgage financing rate for up to 90 days while you search for the perfect place to call home.

Upfront Costs

There are several upfront costs related to your mortgage. Common upfront costs include:

•   Closing costs: From mortgage origination fees and application fees to home inspection and appraisal, you must pay closing costs upfront. These are generally equal to 3% to 6% of the home principal amount.

•   Down payment: Different mortgage types have different down payment requirements. However, depending on the mortgage type, you might be able to put as little as 3% down. First-time homebuyers can sometimes put less down.

•   Property taxes: You may have to pay at least some money toward property taxes at the outset. For example, you might be required to pay six months’ property taxes.

Long-Term Costs

Long-term costs will likely be the largest cost associated with your home purchase. Here are some long-term costs to consider:

•   Mortgage payments: This is the monthly payment against the loan that financed the home purchase.

•   Home maintenance: Homeowners often do work on their homes, from the purely aesthetic to the absolutely necessary. However, these projects can be costly.

•   Property taxes: In most states, you must pay property taxes to your state or municipality. Property taxes can run into the thousands per year.

•   Homeowners insurance: Homeowners insurance isn’t a huge expense, relatively speaking. But the average cost of Progressive’s homeowners policy is between $83 and $138 per month.

Estimated Monthly Payments on a $400K Mortgage

The monthly payment on a $400K mortgage won’t always be the same. Certain factors like the down payment, annual percentage rate (APR), and term will affect how much you pay per month.

For instance, suppose you have a fixed 30-year $400K mortgage at 5% APR. In this case, your monthly payment would be $2,147. If you have a fixed 15-year $400K mortgage at 4.5% APR, your monthly cost would be $3,059. Keep in mind that these estimates don’t include escrow costs. There are also different types of mortgages, such as fixed and adjustable-rate. Your loan repayment may vary significantly depending on the type.

Monthly Payment Breakdown by APR and Term

Certain factors affect how much you pay per month on your mortgage. The biggest factors are typically your APR and mortgage term. Generally, a higher APR increases your monthly payment, as does a shorter repayment term. Use a mortgage calculator to estimate your monthly payment. Here are a few examples of how these calculations may vary depending on the APR and term:

How Much Interest Is Accrued on a $400K Mortgage?

As mentioned, the interest accrued on a $400,000 mortgage depends on several factors. However, the most important are the mortgage term and the APR. Generally, a shorter repayment term will result in higher monthly payments but less interest overall. For example, when comparing a 15-year vs. 30-year mortgage, we see that the 15-year mortgage results in less interest, despite higher monthly payments.

Fifteen-year mortgages often have lower APRs than 30-year mortgages as well. A lower APR also means you pay less interest. However, 15-year mortgages typically have much higher monthly payments than 30-year mortgages.


💡 Quick Tip: Generally, the lower your debt-to-income ratio, the better loan terms you’ll be offered. One way to improve your ratio is to increase your income (hello, side hustle!). Another way is to consolidate your debt and lower your monthly debt payments.

$400K Mortgage Amortization Breakdown

Once approved for a fixed-rate mortgage, you typically pay the same amount each month. However, most of the money you pay will go toward interest in the first few years. Eventually, you can expect to pay more toward the principal than interest. For instance, here is an example of a 30-year $400,000 mortgage with a 6% APR:

What Is Required to Get a $400K Mortgage?

Getting a $400K mortgage usually requires sufficient income and a large enough down payment. The average down payment is 13%. If your income is on the low end, you might be able to make up for it with a larger down payment. Likewise, having a higher income may help if your down payment is small.

It may help to use a housing affordability calculator. This will give you a rough estimate of what you can afford based on your income, monthly expenses, and your down payment.

Your credit score can also be important when applying for a $400K mortgage. Credit scores help lenders determine how likely you are to repay your debts. Thus, a higher credit score can increase your approval odds. There is no definite rule, but a credit score of at least 620 can help when applying for a conventional loan. If you want to learn more about this process, there are mortgage resources that can help.

“If you have multiple debts, you want to make your minimum payments so you don’t hurt your credit score,” Kendall Meade, a Certified Financial Planner at SoFi said. “If you have cash left over after that, you should develop a strategy for which debts to pay off first,” she suggested.

The Takeaway

Buying a home is the largest purchase most Americans make in their lifetime. Many costs come with buying a home, including upfront costs like a down payment and ongoing costs like monthly mortgage payments. Your mortgage payment is likely to be the largest monthly expense you have, and it can vary widely depending on the APR and mortgage term. On a $400,000 mortgage, the monthly payment could range from $1,600 to $2,600, as you can see above.

FAQ

How much house can I afford on a $120,000 salary?

How much house you can afford depends on several factors, and salary is just one of them. You must also consider your mortgage interest rate, down payment, and other debts. If you have $40,000 for a down payment, spend $3,500 per month (not including rent), and your APR is 4.5%, you can afford a home up to about $400,000.

How do you calculate monthly mortgage payments?

To calculate monthly mortgage payments, you must know the loan amount, interest rate, and loan term. The easiest way to calculate your payment is to plug these numbers into an online mortgage calculator.

What is the average total monthly mortgage payment?

The national median monthly mortgage payment in the United States is $1,964 as of February 2023, according to the Mortgage Bankers Association.
