Frequently Asked Questions

How is a monthly mortgage payment calculated?

Your monthly payment uses the formula M = P[r(1+r)ⁿ]/[(1+r)ⁿ−1], where P is the loan principal (home price minus down payment), r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments. For a $240,000 loan at 6.5% for 30 years, the monthly P&I payment is approximately $1,517.

What is a good mortgage interest rate?

A competitive rate is within 0.25–0.5% of the national average for your loan type. Borrowers with a 740+ credit score and 20% down payment typically qualify for the best rates. Even a 0.5% difference on a $300,000 30-year mortgage saves over $30,000 in total interest.

How much house can I afford?

Most lenders follow the 28/36 rule: your monthly mortgage (PITI) should not exceed 28% of gross monthly income, and total debt payments should stay below 36%. On a $6,000/month gross income, that means a maximum mortgage payment of roughly $1,680. Use this calculator to find the payment for any price, then compare it to your budget.
