What will my monthly mortgage payment really be?

The number on the listing is not your payment. Your real monthly cost is PITI: principal and interest on the loan, plus property taxes, plus homeowner's insurance — and, if you put less than 20% down, PMI, plus any HOA dues. This calculator shows the whole stack, live, with a %/$ toggle so you can enter your down payment either way. Change the price, rate, or down payment and watch what actually moves the needle.
