The short answer

Your monthly mortgage payment is the loan’s principal and interest plus property tax, homeowner’s insurance, and any HOA dues. On a California home, principal and interest depend on the loan amount (price minus down payment), the interest rate, and the term — and you should budget roughly another 1.1% of the home’s value per year for property tax under Prop 13, plus insurance.

Frequently asked questions

Four things, often called PITI: principal (paying down the loan), interest (the cost of borrowing), property taxes, and insurance. Many California homes also carry monthly HOA dues, which the lender does not collect but which you still owe.

20% is the common benchmark because it lets you avoid private mortgage insurance (PMI). You can buy with far less — FHA loans allow 3.5% and some conventional loans allow 3% — but a smaller down payment means a larger loan, a higher monthly payment, and usually PMI until you reach 20% equity.

Strongly. On a 30-year loan, even a 1-point rate change moves the principal-and-interest payment by roughly 10–12%. This calculator pre-fills the live 30-year fixed rate published by the Federal Reserve (FRED), but your actual rate depends on your credit, down payment, and lender quote.

Yes. It adds California property tax (defaulting to about 1.1% of the price per year, the Prop 13 statewide average) plus a monthly insurance figure and optional HOA, so the headline number reflects your all-in monthly cost rather than just principal and interest.
