Mortgage Payment on a $600k House

The monthly payment on a $600,000 house at today's 30-year fixed rate of 6.25% (6.26% APR, verified July 2026) is about $3,630 with 20% down, including principal, interest, estimated taxes, and insurance. To afford it, you generally need a household income between about $97,000 and $134,000, depending on your down payment and other debts.

That payment and the income behind it move with how much you put down and how lenders actually measure what you can carry, which is more flexible than the usual 28% rule of thumb.

What is the monthly payment on a $600k house?

At 6.25% with 20% down, the payment on a $600,000 home is about $3,630 a month before any HOA dues. Here is how that breaks down:

Cost component	Amount (20% down)
Loan amount	$480,000
Principal and interest	about $2,955/mo
Property taxes (~1.1%)	about $550/mo
Homeowners insurance	about $125/mo
Total payment	about $3,630/mo

With a smaller down payment the payment rises, both because the loan is larger and because you add mortgage insurance:

Down payment	Loan amount	Principal & interest	Est. total/mo
5% ($30,000)	$570,000	about $3,510 + PMI	about $4,470
10% ($60,000)	$540,000	about $3,325 + PMI	about $4,270
20% ($120,000)	$480,000	about $2,955	about $3,630

What income do I need to afford a $600k house?

Most buyers need a household income between about $97,000 and $134,000 a year, depending on down payment and existing debt. To carry the roughly $3,630 payment plus about $400 in other monthly debts, you would need about $134,000 a year at a conservative 36% debt-to-income ratio, about $112,000 at 43%, and about $97,000 at 50%.

Where you fall in that range depends on the qualifying rules below, not just your salary.

Is the 28% rule the real limit?

No. The 28% front-end guideline is a cushion, not the ceiling lenders use. Conventional loans run through automated underwriting can approve total debt-to-income ratios up to 50% with compensating factors like strong credit or cash reserves, which is why the 28% rule isn't the real qualifying limit.

A buyer earning $110,000 who assumes housing must stay near 28% of income might think a $600,000 home is a stretch, when with good credit and reasonable debts they may qualify comfortably. As a broker running files through Fannie Mae and Freddie Mac automated underwriting across 240-plus wholesale lenders, I see these higher-ratio approvals regularly. A $600,000 home also stays under the 2026 conforming loan limit of $832,750 at any normal down payment, so you keep conventional financing rather than moving to a jumbo loan.

What else do I need besides the down payment?

Beyond the down payment, plan for closing costs and reserves. Closing costs on a $600,000 purchase typically run 2% to 5% of the price, so about $12,000 to $30,000, covering lender fees, title, escrow, and prepaids.

Lenders often want a couple of months of payments held in reserve after closing, and retirement accounts usually count toward that without being withdrawn. Sellers can also contribute toward closing costs. I am Emmett Clark, a mortgage broker licensed in 18 states with more than 20 years of experience, and structuring a purchase at this level to balance down payment, monthly cost, and cash reserves is a big part of what I do.

Can I lower the monthly payment on a $600k house?

Yes, several ways. A larger down payment reduces both the loan and, once you hit 20%, the mortgage insurance. Buying down the rate with discount points lowers the interest portion. And choosing the right loan structure for your situation can shave the payment.

The biggest lever is often the rate itself, which is exactly why shopping multiple lenders matters. With access to 240-plus wholesale lenders, the difference between the first rate you are quoted and the best available can change this payment by a meaningful amount each month.
