If you’re wondering how much income you need for a $400K house, the answer is about $75,000 to $93,000 a year, with no other monthly debts and a 45% debt-to-income (DTI) ratio. The $75,000 figure assumes 20% down. With 3% down, the larger loan and private mortgage insurance (PMI) raise the monthly payment, bringing the required income to about $93,000.
With 20% down, the income can drop to about $68,000 at a 50% ratio, the maximum Fannie Mae allows when its automated underwriting system approves the loan. Car payments, student loans, and HOA dues push the required salary higher.
Key Takeaways
- With 20% down, the estimated monthly housing payment on a $400,000 house is about $2,820 at a 7.500% rate (the Mortgage News Daily 30-year fixed index on September 28, 2026), including property taxes and homeowners insurance.
- A $400,000 house needs about $75,000 a year in income with 20% down and about $93,000 with 3% down, at a 45% debt-to-income ratio and no other monthly debts.
- A full 1% change in the interest rate moves the income needed for a $400K house with 20% down by about $5,700 a year.
- A $400 monthly car payment raises the income needed for a $400K house by about $10,700 a year at a 45% debt-to-income ratio.
- FHA financing with 3.5% down on a $400,000 house needs about $91,000 a year at a 45% ratio, and FHA’s automated scorecard can approve ratios as high as 56.9% for some borrowers, which lowers the income needed to about $72,000.
Start With the Monthly Payment
The salary you need starts with the monthly payment. Lenders check whether your total housing payment, plus your other debts, fits within an acceptable share of your gross income, which is your debt-to-income ratio.
A $400,000 house with 20% down means an $80,000 down payment and a $320,000 loan. At 7.500%, the Mortgage News Daily 30-year fixed index on September 28, 2026, the estimated monthly payment on a 30-year fixed loan breaks down like this:
- Principal and interest: $2,237
- Property taxes: $333, or $4,000 a year at 1% of the price
- Homeowners insurance: $250, or $3,000 a year
- Private mortgage insurance: $0, since the down payment is 20%
That’s about $2,820 a month in principal, interest, taxes, and insurance (PITI). At a 45% ratio, a $2,820 payment calls for $6,267 in gross monthly income, or about $75,000 a year before taxes.
These figures show the income a lender needs to see. Whether the payment is comfortable is a separate question, since $2,820 of $6,267 goes to housing before income taxes, retirement savings, and everyday costs.
To see the income needed at other prices, read how much income you need to buy a house. If you’re starting from a loan amount instead of a price, the income needed for a $400K mortgage is higher, since a $400,000 loan finances about a $500,000 house with 20% down.
How Much Income You Need for a $400K House, by Down Payment
Your down payment affects the salary you need. A larger down payment shrinks the loan, and at 20% down, private mortgage insurance drops off entirely. Across common down payments on a $400,000 house, the payment and the income needed change like this:
| Down payment | Loan amount | Estimated monthly payment | Income needed at 45% DTI | Income needed at 50% DTI | What changes |
|---|---|---|---|---|---|
| 20% ($80,000) | $320,000 | $2,820 | $75,000 | $68,000 | No mortgage insurance |
| 10% ($40,000) | $360,000 | $3,187 | $85,000 | $77,000 | Includes $87 a month in PMI |
| 5% ($20,000) | $380,000 | $3,379 | $90,000 | $82,000 | Includes $139 a month in PMI |
| 3% ($12,000) | $388,000 | $3,474 | $93,000 | $84,000 | Includes $178 a month in PMI |
| FHA 3.5% ($14,000) | $392,755* | $3,406 | $91,000 | $82,000 | Includes $177 a month in FHA annual premium; about $72,000 at 56.9% |
The FHA loan is $386,000 plus the 1.75% upfront premium of $6,755. Payments include principal, interest, property taxes at 1%, homeowners insurance at $250 a month, and mortgage insurance where shown, and exclude HOA dues and flood insurance. PMI is priced at a 740 to 759 credit score. Income at 50% is rounded up because 50% is the conventional maximum; for FHA, 50% is a comparison point below its 56.9% ceiling.
Putting 20% down instead of 3% lowers the income needed by about $18,000 a year at a 45% ratio, and it takes $68,000 more for the down payment. Closing costs come on top of the down payment at every level, and the Loan Estimate you receive after applying lists them.
FHA with 3.5% down needs slightly less income than conventional with 3% down, $91,000 versus $93,000 at a 45% ratio. The FHA rate is lower, 7.125% versus 7.500% on the Mortgage News Daily indexes for September 28, 2026, and that more than offsets the upfront premium added to the loan.
How Do Interest Rates Change the Salary You Need?
Rates change the payment, and the payment changes the income you need. On the same $320,000 loan, principal and interest are $2,023 a month at 6.500%, $2,129 at 7.000%, and $2,237 at 7.500%.
A full 1% in rate moves the payment by $214 a month and the income needed at a 45% ratio by about $5,700 a year. Your quoted rate depends on your credit score, down payment, and loan program.
A higher rate isn’t automatically a dealbreaker if the monthly payment fits your budget. Lenders qualify you on today’s rate and payment, and market rates change over time. If they fall after you buy, a refinance can lower the payment, depending on your credit and your home’s value at that point. A refinance starts a new loan term, which extends how long you’ll be paying.
For purchases that close with us, JVM’s Rate Drop Free-Fi provides a lender credit when you refinance the same home and lock the new rate between 120 days and 36 months after closing. Refinance loans of $350,000 or more get up to $4,500 toward the first appraisal, credit report, tax certification, recording, flood certification, notary, and processing and underwriting fees. Loans of $150,000 to $349,999 get up to $1,500 toward processing and underwriting fees.

Debt-to-Income: How Lenders Decide What You Can Afford
Lenders compare your monthly debts, including the new housing payment, to your gross monthly income. That comparison determines how much of your income lenders allow you to put toward housing, and the Consumer Financial Protection Bureau explains how the debt-to-income ratio is calculated.
For conventional loans approved through Desktop Underwriter, Fannie Mae’s automated underwriting system, the maximum debt-to-income ratio is 50%. The 45% benchmark in these estimates is the highest ratio Fannie Mae allows on a manually underwritten conventional loan, and only with the credit score and reserves its guidelines require. FHA’s automated scorecard can approve ratios as high as 56.9% for some borrowers.
A loan on a $400,000 house is well under the 2026 conforming loan limit of $832,750, the largest loan Fannie Mae and Freddie Mac buy, so the stricter rules for larger jumbo loans don’t apply.
Other debts come out of the same income before the mortgage does. A $400 car payment raises the income needed at a 45% ratio by about $10,700 a year, and a $300 student loan payment raises it by $8,000. Student loans in deferment still count, and conventional and FHA loans each set the payment a lender uses when your credit report shows $0 (usually 0.5% or 1% of the outstanding balance).
Paying off a debt before you apply lowers your debt-to-income ratio by the monthly payment that goes away, so the size of the monthly payment matters more than the size of the balance. When looking at a cash-for-cash comparison, paying off debt is generally the most effective way to lower your DTI compared to increasing your down payment. Always talk to your mortgage lender before paying off a large amount of debt to improve your DTI to ensure it has the intended result.
Loan Options for a $400K House
A $400,000 house qualifies for the full menu of financing:
- Conventional loans with as little as 3% down for eligible buyers, including first-time buyers. PMI applies below 20% down and isn’t permanent; federal law and your loan servicer set the conditions for removing it.
- FHA loans with 3.5% down at a 580 or higher credit score. FHA charges a 1.75% upfront premium and an annual mortgage insurance premium that lasts for the life of the loan when you put less than 10% down.
- VA loans have no down payment requirement for eligible veterans and service members.
The right fit depends on your down payment, credit, and debts, and each one changes the income you need. To see how the income needed changes at a higher price, read the salary needed for a $700K home.
Where Your Credit Score Fits In
Your credit score changes what you pay each month. Below 20% down, your score affects the cost of mortgage insurance. At 10% down, PMI on a $360,000 loan costs $75 a month at a 760 or higher score and $216 at a 660 to 679 score, based on MGIC’s published rates.
That $141 monthly difference changes the income needed at a 45% ratio by about $3,800 a year. Your score also affects your rate, because Fannie Mae adds pricing adjustments to conventional loans based on credit score and down payment.

How We Confirm the Income You Need at JVM
A pre-approval replaces the assumptions in these estimates with your own figures, in four steps.
- We count your income the way your loan program does. W-2 base pay, overtime, bonuses, and self-employment income each have their own documentation and history rules.
- We use your actual monthly debts. Your credit report shows the payments that count toward your debt-to-income ratio.
- We price your real scenario. Your credit score, down payment, the county’s tax rate, and your insurance quote all go into the payment.
- We submit your application to automated underwriting. Fannie Mae’s Desktop Underwriter or FHA’s TOTAL Scorecard returns the maximum debt-to-income ratio for your loan, and your pre-approval amount is based on that result.
Recent pay stubs, your last two years of W-2s or tax returns, and two months of bank statements are what you’ll need to start.
Assumptions Behind the $400K Income Estimates
If your rate, tax bill, insurance premium, or mortgage insurance cost differs from these four assumptions, the income you need will change.
| Assumption | Assumed | What moves it for you |
|---|---|---|
| Interest rate | 7.500% conventional, 7.125% FHA | Mortgage News Daily daily index as of September 28, 2026, rounded to the nearest eighth of a percent, which is how lenders quote. The index reflects roughly par pricing, meaning no discount points or lender credits. A real quote shows either a cost for discount points or a credit from the lender, and your rate depends on your credit score, down payment, and loan program. |
| Property taxes | 1% of the price, or $4,000 a year | Effective rates range from about 0.3% to 2.2% by state, which is $1,200 to $8,800 a year on a $400,000 house. At 2.2%, taxes add $400 a month, which raises the income needed at a 45% ratio by about $10,700. Your county assessor publishes the rate for any parcel. |
| Homeowners insurance | $250 a month, or $3,000 a year | National average premiums in 2026 range from about $2,150 to $2,800 a year, depending on the survey and the coverage amount. The $3,000 assumption is above those averages, which leaves room for higher-cost areas. Homes in wildfire, hurricane, and hail regions pay more, and a newer roof or a higher deductible can lower the premium. |
| Mortgage insurance | MGIC published rates at a 740 to 759 credit score; FHA premiums set by HUD | Conventional PMI is 0.29% of the loan a year at 10% down, 0.44% at 5%, and 0.55% at 3%, with none at 20% down. MGIC's published rates show the cost at other credit scores. FHA adds a 1.75% upfront premium financed into the loan and a 0.55% annual premium. |
Income figures are rounded to the nearest $1,000. At the 50% conventional maximum and the 56.9% FHA ceiling, they’re rounded up, so the payment never exceeds that share of income. At 45%, rounding can put the actual ratio a few tenths of a point above or below 45%.
HOA dues and flood insurance are left out because they depend on the property. Both count against your debt-to-income ratio, and a $300 monthly HOA due raises the income needed at a 45% ratio by $8,000 a year.

FAQ
How much should you make to afford a $400K house?
You need about $75,000 to $93,000 a year to afford a $400K house at a 45% debt-to-income ratio with no other monthly debts and a 7.500% conventional rate. The low end assumes 20% down, and the high end assumes 3% down. At the 50% conventional maximum, the income needed for a $400K house with 20% down is about $68,000.
How much is the monthly payment on a $400,000 house?
The estimated monthly payment on a $400,000 house is about $2,820 with 20% down at 7.500%, including $2,237 in principal and interest, $333 in property taxes, and $250 in homeowners insurance. With 3% down, the estimated payment on a $400,000 house is about $3,474, including $178 a month in private mortgage insurance. The actual payment depends on your rate, tax bill, and insurance quote.
How much down payment do you need for a $400,000 home?
A $400,000 home needs as little as $12,000 (3%) on a conventional loan for eligible buyers, or $14,000 (3.5%) on an FHA loan with a 580 or higher credit score. Putting $80,000 (20%) down on a $400,000 home removes private mortgage insurance and lowers the income needed. Eligible veterans and service members can use a VA loan with no down payment, and closing costs are separate from the down payment.
Do you need a high credit score to buy a $400,000 home?
No. Conventional loans start at a 620 credit score, and FHA allows 3.5% down starting at a 580 credit score. A higher credit score lowers mortgage insurance on a $400,000 home: PMI at 10% down costs $75 a month at a 760 or higher score versus $216 at a 660 to 679 score.
How can you afford a $400K house on a lower income?
A larger down payment, FHA financing, or a co-borrower’s income can each lower the salary needed to afford a $400K house. With 20% down and no other debts, the income needed is about $68,000 at the 50% conventional maximum. With 3.5% down, FHA’s automated scorecard can approve ratios as high as 56.9% for some borrowers, which lowers the income needed to about $72,000, compared with $91,000 at a 45% ratio. At 56.9%, housing takes $3,406 of $6,000 in gross monthly income.
Is the income for a $400K mortgage the same as for a $400K house?
No. A $400K mortgage is the loan amount, and with 20% down it finances about a $500,000 house, so a $400K mortgage needs more income than a $400K house. A $400K house with 20% down has a $320,000 mortgage.
