How It Works
With 20% down ($80k) on a $400k home, your loan is $320,000. At 6.75% for 30 years your P+I payment is roughly $2,075/month.
Add taxes (~$400/mo) and insurance (~$125/mo) and your real PITI payment is around $2,600/month — the number lenders actually care about.
Lenders target a 28% front-end debt-to-income ratio, which generally means ~$110k–130k annual income is needed to comfortably qualify.
A 15-year term would raise your P+I to ~$2,830/month but cut total interest from ~$428k down to roughly $185k.
Frequently Asked Questions
What income do I need for a $400,000 house?
Expect to need $110k–130k annual income with 20% down and minimal other debt. Drop to 3.5% down via FHA and income requirements can push toward $135k–150k due to PMI and a larger loan.
How much is a $400k mortgage payment per month?
With 20% down at 6.75% for 30 years, PITI lands around $2,600/month including typical property taxes and homeowners insurance.
Should I put 10% or 20% down on $400k?
20% avoids PMI ($200–300/month savings) and gets you better rates. 10% down lets you buy sooner but costs ~$200/mo more in PMI until you hit 20% equity.
