Frequently Asked Questions

1. What is included in a mortgage payment?

Typically, your monthly mortgage payment includes principal, interest, property taxes, and insurance (homeowners and PMI).

2. What is PMI and when do I pay it?

PMI (Private Mortgage Insurance) is required when your down payment is less than 20%. It protects the lender, not the borrower.

3. Can I reduce my mortgage payment?

Yes. You can lower your payment by increasing your down payment, extending your loan term, or shopping for a lower interest rate.

4. How does the interest rate affect the total loan cost?

Even small differences in interest rate can significantly affect total payments over the life of the loan.

5. Should I get a 15-year or 30-year mortgage?

A 15-year mortgage has higher monthly payments but much lower total interest. A 30-year loan offers lower payments but higher interest costs over time.
