What Salary Do You Need for a $400,000 Mortgage?
Under standard assumptions — a 6.5% interest rate, 20% down payment on a $500,000 home, Texas average property tax of approximately 1.8%, and around $150 per month for homeowners insurance — you typically need a gross annual income of approximately $123,000 to $147,000 to comfortably qualify for a $400,000 mortgage.
The lower end applies to debt-free buyers with strong credit. The higher end is more realistic if you carry car payments, student loans, or credit card debt. The actual qualifying income depends heavily on your debt-to-income ratio, credit score, and the loan program you select.
Quick Reference
- •Conservative (no other debts): ~$123,000/year
- •Typical (some debt, conventional): ~$147,000/year
- •FHA with stretched DTI: ~$100,000–$115,000/year
Breaking Down the Monthly Payment
Your full monthly housing payment — what lenders use to qualify you — is PITI: Principal, Interest, Taxes, and Insurance. Here's how it shakes out on a $400,000 mortgage in Texas.
PITI on a $400,000 Mortgage (Example)
- Principal & Interest (6.5%, 30 years): ~$2,528/month
- Property Taxes (1.8% on $500K home): ~$750/month
- Homeowners Insurance: ~$150/month
- Total PITI: ~$3,428/month
Assumes 20% down payment ($100,000), no PMI, and excludes HOA dues. Actual figures vary with rate, location, and insurance.
Less than 20% down adds private mortgage insurance — typically $100–$250/month on a $400,000 conventional loan, depending on credit score and exact loan-to-value ratio.
How the 28/36 Rule Applies
Lenders use the 28/36 rule as a starting point. Your housing payment (PITI) should not exceed 28% of gross monthly income, and your total debt should stay under 36% of gross income when the new mortgage is included.
Working backwards from a $3,428 PITI:
- •$3,428 ÷ 0.28 = $12,243 in required gross monthly income
- •That equals approximately $147,000 in annual income
In practice, lenders frequently approve loans above the 28% front-end ratio when the borrower has compensating factors — strong reserves, excellent credit, low overall debt — which is why $123,000 is also a realistic floor for a clean credit profile.

Scenarios That Change the Required Salary
Scenario A: 20% Down, No Other Debts
With $100,000 down, no PMI, and zero other monthly debt obligations, you can comfortably qualify on roughly $123,000–$130,000 annually.
Scenario B: 10% Down, $700/month in Other Debt
10% down ($50,000) adds approximately $150–$250/month in PMI. Combined with $700 in other monthly debts (auto + credit cards), the required income climbs to around $160,000–$175,000 per year to satisfy back-end DTI.
Scenario C: FHA Loan, 3.5% Down
FHA's flexible DTI tolerance — often up to 43%–50% — means a borrower earning $100,000–$115,000 per year can frequently qualify for a $400,000 FHA loan, where it stays within county FHA limits.
FHA vs. VA vs. Conventional at $400K
$400,000 is comfortably below the 2025 conforming loan limit, so conventional financing is fully available. Each loan program offers different trade-offs at this price point.
Conventional Loans
Best long-term value for borrowers with credit scores of 700+ and at least 5% down. PMI drops off automatically once you reach 22% equity, and there's no upfront mortgage insurance like FHA.
FHA Loans
Useful for buyers with credit scores of 580–680 or higher DTI. Mortgage insurance is permanent on most FHA loans now, so many buyers refinance into a conventional loan after building equity.
VA Loans
For eligible veterans, VA is almost always the best option — 0% down, no monthly mortgage insurance, and competitive rates. A $400,000 VA loan is typically within entitlement limits.
Jumbo Loans
Not needed at $400K — you remain well within conforming loan limits in every Texas county.
Texas-Specific Considerations
Texas property taxes have an outsized impact at the $400K loan level. On a $500,000 home at the 1.8% statewide average, you're looking at roughly $9,000 per year — about $750 per month escrowed into your mortgage. That tax line alone can push borrowers into a higher qualifying income bracket compared to states with lower property taxes.
Texas also has higher-than-average homeowners insurance premiums in many regions, particularly along the Gulf Coast and in hail-prone areas of North and West Texas. Get quotes early in your home search — insurance costs can shift your monthly payment by $50–$150.
On the bright side, Texas has no state income tax. Your gross income translates to more take-home pay than in many other states, which makes higher housing payments more manageable in practice even when lender DTI math is the same.
Frequently Asked Questions
What salary do you need for a $400,000 mortgage?
Under common assumptions — a 6.5% interest rate, 20% down payment, Texas average property tax of about 1.8%, and roughly $150/month in homeowners insurance — you generally need a gross annual income of approximately $123,000 to $147,000 to comfortably qualify for a $400,000 mortgage. The required income rises if you carry significant other debts.
What is the monthly payment on a $400,000 mortgage?
On a 30-year fixed $400,000 mortgage at 6.5%, principal and interest run about $2,528 per month. Adding Texas property taxes (around $750/month on a $500,000 home) and homeowners insurance (about $150/month) brings the full PITI payment to approximately $3,428 per month.
Can you afford a $400,000 home on a $100k salary?
It is tight. A $100,000 salary equals about $8,333 in gross monthly income, which caps your housing payment at roughly $2,333 under the 28% rule — well below the $3,428 PITI in our example. To make it work you would need a much larger down payment, no other monthly debts, or to consider a less expensive home in the $300K range.
How much down payment do I need for a $400,000 house?
Down payment options include 3% conventional ($12,000), 3.5% FHA ($14,000), 0% VA for eligible veterans, and 20% conventional ($80,000) to avoid private mortgage insurance. At this price point, putting at least 10% down is often a good balance between cash conservation and lower monthly payments.
What credit score do you need for a $400,000 mortgage?
Most lenders look for a credit score of at least 620 for a $400,000 conventional mortgage, with scores of 740 or higher unlocking the best interest rates. FHA loans accept scores as low as 580 with 3.5% down. At this loan size, even a small rate difference adds up significantly over 30 years, so optimizing your credit is worth the effort.
What is the property tax on a $400,000 home in Texas?
With Texas property taxes averaging about 1.8% of assessed value, a $400,000 home will run roughly $7,200 per year in property taxes, or about $600 per month escrowed into your mortgage payment. Counties like Travis, Fort Bend, and Collin tend to be on the higher end, while many rural and West Texas counties are lower.
How much income do I need for a $400,000 FHA loan?
FHA allows debt-to-income ratios up to roughly 43% to 50%, so you may qualify for a $400,000 FHA loan with an annual income of around $100,000 to $115,000, depending on your other monthly debts. Note that FHA loans are subject to county loan limits — a $400,000 loan amount is within FHA limits in most Texas counties, but check before assuming.
What are closing costs on a $400,000 mortgage in Texas?
Closing costs in Texas typically run 2% to 5% of the loan amount, so on a $400,000 mortgage you should budget $8,000 to $20,000. This includes lender fees, title insurance, appraisal, prepaid taxes and insurance, and recording fees. Seller credits can offset a portion of these costs in many transactions.
