Mortgage payment on a $675K house
$4,477 a month with 20% down at 7.11% — including property tax and insurance. You'd need an income of about $191,900.
On a $675,000 home with $135,000 (20%) down, you borrow $540,000. At 7.11% (30-year fixed, Freddie Mac average for the week of Nov 12, 2026), principal and interest come to $3,633 a month. Adding property tax at the U.S. average of 0.9% ($507) and insurance ($338) gives $4,477. Over 30 years you would pay $767,741 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 | $135,000 | $540,000 | $3,633 | $0 | $844 | $4,477 | $191,900 |
| 10% down | $67,500 | $607,500 | $4,087 | $253 | $844 | $5,184 | $222,200 |
| 5% down | $33,750 | $641,250 | $4,314 | $267 | $844 | $5,425 | $232,500 |
| 3.5% down (FHA) | $23,625 | $662,774 | $4,459 | $299 | $844 | $5,601 | $240,100 |
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.
