Frequently asked questions
- How much should I put down?
- Twenty percent avoids mortgage insurance, but many buyers successfully purchase with 3.5-10% down and accept PMI.
- What is PMI?
- Private mortgage insurance, typically 0.3-1.5% of the loan per year, required when the down payment is under 20%.
- Does the estimate include taxes and insurance?
- No. Add property tax, homeowners insurance and any HOA fees on top of the principal and interest shown.
- How is the monthly payment calculated?
- The standard amortization formula for fixed-rate loans, the same one lenders use.
