Frequently Asked Questions

What is PMI and how much does it cost?+
Private Mortgage Insurance (PMI) protects the lender if you default when your down payment is below 20%. PMI typically costs 0.5%–1.5% of the loan amount per year, paid monthly. For a $300,000 loan, that's roughly $125–$375/month. PMI can be canceled once you reach 20% equity in your home (either through payments or appreciation). Request cancellation in writing when you hit 20% equity.
What are closing costs?+
Closing costs are fees paid at settlement when you finalize your home purchase. They typically range from 2%–5% of the loan amount and include lender fees (origination, underwriting), third-party fees (appraisal, title insurance, survey), prepaid items (homeowner's insurance, property taxes, prepaid interest), and government fees (recording fees, transfer taxes). Ask your lender for a Loan Estimate to see itemized costs early in the process.
