Frequently Asked Questions

How is the monthly mortgage payment calculated?

Monthly payment is calculated using the loan amount, interest rate, and loan term with the formula: M = P × [r(1+r)^n] / [(1+r)^n – 1], where M is monthly payment, P is principal, r is monthly interest rate, and n is number of payments.

What is PMI and when do I need it?

PMI (Private Mortgage Insurance) is typically required when your down payment is less than 20% of the home's value. It protects the lender if you default on the loan and usually costs 0.3% to 1.5% of the loan amount annually.

Should property taxes and insurance be included in my mortgage payment?

Yes, most lenders require an escrow account for property taxes and homeowners insurance. This ensures these critical expenses are paid on time and protects both you and the lender.

How does the loan term affect my total cost?

Shorter loan terms (like 15 years) have higher monthly payments but significantly lower total interest costs. Longer terms (like 30 years) have lower monthly payments but cost much more in total interest over the life of the loan.

What's the difference between APR and interest rate?

Interest rate is the cost of borrowing the principal loan amount. APR (Annual Percentage Rate) includes the interest rate plus additional costs like origination fees, making it a more comprehensive measure of loan cost.
