Mortgage payment on a $850K house
$5,638 a month with 20% down at 7.11% — including property tax and insurance. You'd need an income of about $241,600.
On a $850,000 home with $170,000 (20%) down, you borrow $680,000. At 7.11% (30-year fixed, Freddie Mac average for the week of Nov 12, 2026), principal and interest come to $4,574 a month. Adding property tax at the U.S. average of 0.9% ($638) and insurance ($425) gives $5,638. Over 30 years you would pay $966,785 in interest.
Payment by down payment
Putting less than 20% down means a bigger loan and mortgage insurance, so the monthly payment rises:
| Down payment | Cash down | Loan | Principal + interest | PMI / MIP | Tax + insurance | Total / month | Income needed |
|---|---|---|---|---|---|---|---|
| 20% down | $170,000 | $680,000 | $4,574 | $0 | $1,063 | $5,638 | $241,600 |
| 10% down | $85,000 | $765,000 | $5,146 | $319 | $1,063 | $6,528 | $279,800 |
| 5% down | $42,500 | $807,500 | $5,432 | $336 | $1,063 | $6,832 | $292,800 |
| 3.5% down (FHA) | $29,750 | $834,604 | $5,614 | $376 | $1,063 | $7,054 | $302,300 |
Assumes a 30-year fixed loan at 7.11%, property tax of 0.9% of the home value a year, homeowners insurance of 0.6% a year, PMI of 0.5% of the loan a year when the down payment is under 20%, and FHA mortgage insurance of 0.55% a year plus a 1.75% upfront premium added to the loan. Your rate, taxes and insurance will differ.
