Mortgage payment on a $3M house
$19,898 a month with 20% down at 7.11% — including property tax and insurance. You'd need an income of about $852,800.
On a $3,000,000 home with $600,000 (20%) down, you borrow $2,400,000. At 7.11% (30-year fixed, Freddie Mac average for the week of Nov 12, 2026), principal and interest come to $16,145 a month. Adding property tax at the U.S. average of 0.9% ($2,253) and insurance ($1,500) gives $19,898. Over 30 years you would pay $3,412,183 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 | $600,000 | $2,400,000 | $16,145 | $0 | $3,753 | $19,898 | $852,800 |
| 10% down | $300,000 | $2,700,000 | $18,163 | $1,125 | $3,753 | $23,041 | $987,500 |
| 5% down | $150,000 | $2,850,000 | $19,172 | $1,188 | $3,753 | $24,112 | $1,033,400 |
| 3.5% down (FHA) | $105,000 | $2,945,663 | $19,816 | $1,327 | $3,753 | $24,895 | $1,066,900 |
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.
