Mortgage payment on a $450K house
$2,985 a month with 20% down at 7.11% — including property tax and insurance. You'd need an income of about $127,900.
On a $450,000 home with $90,000 (20%) down, you borrow $360,000. At 7.11% (30-year fixed, Freddie Mac average for the week of Nov 12, 2026), principal and interest come to $2,422 a month. Adding property tax at the U.S. average of 0.9% ($338) and insurance ($225) gives $2,985. Over 30 years you would pay $511,827 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 | $90,000 | $360,000 | $2,422 | $0 | $563 | $2,985 | $127,900 |
| 10% down | $45,000 | $405,000 | $2,724 | $169 | $563 | $3,456 | $148,100 |
| 5% down | $22,500 | $427,500 | $2,876 | $178 | $563 | $3,617 | $155,000 |
| 3.5% down (FHA) | $15,750 | $441,849 | $2,972 | $199 | $563 | $3,734 | $160,000 |
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.
