How it’s solved

Worked on the example above, step by step — follow along and you can do it on paper next time, no tool required.

PITI is the true monthly housing cost: Principal, Interest, Taxes and Insurance bundled together.
Loan amount = price − down payment
$400,000.00 − $80,000.00 = $320,000.00
Monthly rate and number of payments
6.9 ÷ 100 ÷ 12 = 0.00575 ; 30 × 12 = 360
Principal & interest via the amortization formula
= $2,107.52
Add monthly tax and insurance (each annual figure ÷ 12)
$2,107.52 + $4,800.00 ÷ 12 + $1,500.00 ÷ 12 = $2,632.52
