Frequently Asked Questions Does this include property tax and insurance? No — this shows principal and interest only. Property tax, homeowners insurance, HOA fees and PMI are added on top by your lender.
How does a bigger down payment help? It reduces the loan amount, so both the monthly payment and total interest fall; 20% down also avoids PMI on conventional loans.
Is this a loan offer? No. This is an estimate for planning only — actual terms come from your lender.
