The short answer: To afford a $400,000 house, you need approximately $110,000/year with 20% down or $133,000/year with 3.5% down (FHA). Your monthly payment will run $2,500-$3,100 depending on your down payment and current interest rates.
$400,000 sits at or slightly above the national median and represents the most common price point in suburban markets surrounding major cities. In Phoenix, Tampa, Dallas, and Atlanta, $400K buys a modern 3-4 bedroom home. In San Francisco, Seattle, or the New York suburbs, it does not come close.
The income requirement puts this firmly in dual-income territory for most markets. Saving $80,000 for a 20% down payment while also managing rent, student loans, and other expenses is the primary barrier for buyers at this level — though lower down payment options exist if you have strong income but limited savings.

Income Needed to Afford a $400,000 Home
Based on the 28% front-end DTI rule:
| Down Payment | Loan Amount | Monthly PITI | Income Required |
|---|---|---|---|
| 3% ($12,000) | $388,000 | $3,127 | $134,000/yr |
| 3.5% FHA ($14,000) | $386,000 | $3,111 | $133,300/yr |
| 5% ($20,000) | $380,000 | $3,063 | $131,300/yr |
| 10% ($40,000) | $360,000 | $2,904 | $124,400/yr |
| 20% ($80,000) | $320,000 | $2,581 | $110,600/yr |
Assumes 6.75% rate, 30-year term, $400/mo taxes, $160/mo insurance. PMI included for <20% down.
At $400K, the conventional conforming loan limit ($806,500 in most counties for 2026) is not a concern — you are well within standard lending guidelines. This means you have access to the best rates available for conventional mortgages.
Rate shopping matters here: Getting quotes from 3-5 lenders can save 0.25-0.5% on your rate. On a $320K loan (20% down), that translates to $50-$100/month — over $18,000-$36,000 over a 30-year loan.

Can You Actually Afford a $400K House?
Meeting the income threshold is just the first step. Ask yourself these questions before committing:
You’re likely in good shape if:
- Your total monthly debt payments (car, student loans, credit cards) are under $400/month
- You have 6 months of expenses saved beyond your down payment
- Your employment is stable and income is predictable
- You’re planning to stay in the home 5+ years
You may want to reconsider or wait if:
- You’re stretching to hit the 28% DTI ratio with no room to spare
- Your down payment depletes most of your savings
- You’re expecting a major life change (career shift, growing family) that affects finances
- Property taxes in your target area are significantly higher than the $333/month estimate
Tips for Buying at the $400K Price Point
-
Consider a 15-year mortgage if your income supports it — At $320K borrowed, you’d pay $2,822/month vs. $2,076, but save $140,000+ in interest and build equity faster.
-
Don’t skip the inspection — At this price, major issues like roof replacement ($15K+) or HVAC ($8K+) can wreck your budget. This isn’t the price point to waive contingencies.
-
Budget for immediate expenses — Expect $5,000-$10,000 in Year 1 for furniture, minor repairs, lawn equipment, and things you don’t realize you need until move-in day.
-
Lock your rate strategically — If rates are volatile, ask about float-down options. A 30-day lock is standard; 45-60 day locks cost more but provide security in uncertain markets.
-
Get pre-approved, not just pre-qualified — Pre-approval involves actual income verification and gives you credibility with sellers in competitive markets.
