❓ Frequently Asked Questions

How is monthly mortgage payment calculated?

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

What is included in a mortgage payment?

A mortgage payment typically includes principal, interest, property taxes, homeowners insurance, and possibly PMI (Private Mortgage Insurance) if down payment is less than 20%.

How much should my down payment be?

A 20% down payment is ideal to avoid PMI, but many loans allow 3-10% down. FHA loans require as little as 3.5% down, while VA loans can be 0% down for eligible veterans.
