California Mortgage Calculator - Monthly Payment with Taxes, PMI & Insurance
California property tax starts with Proposition 13's 1% general ad valorem limit, with taxable assessed value generally capped at 2% annual growth until a change in ownership or new construction. County pages override this file with BOE 2024-25 countywide average ad valorem rates where available. The statewide file also models the $7,000 homeowners' exemption and the county documentary transfer tax of $0.55 per $500 of value. CalHFA MyHome is modeled for conventional loans as 3% of purchase price, using the lowest current county income limit as a conservative statewide default; county-specific CalHFA limits can override this later.

Frequently Asked Questions
What property tax rate should California buyers expect?
California's base ad valorem property tax is commonly modeled at 1% of taxable assessed value under Proposition 13. Voter-approved debt, Mello-Roos, parcel taxes, and direct assessments can make the actual bill higher.
How does the California homeowners' exemption work?
A qualifying owner-occupied primary residence can receive a $7,000 reduction in taxable assessed value after filing with the county assessor.
Does California charge a mortgage recording tax?
California does not use a New York-style mortgage recording tax. The statewide closing-tax estimate here models the county documentary transfer tax on real property transfers; some cities add their own transfer tax.
Does this mortgage calculator include taxes and insurance?
Yes. This calculator estimates your full monthly housing payment by combining principal and interest with property taxes, homeowners insurance, and PMI when your down payment is below 20%. The result reflects a PITI-style payment rather than principal and interest alone, which helps you compare homes and loan scenarios more realistically before talking to a lender.
When does PMI apply on a mortgage?
Private Mortgage Insurance (PMI) typically applies when your loan-to-value ratio exceeds 80%, meaning your down payment is less than 20% of the purchase price. PMI is usually added to the monthly payment until you reach sufficient equity. This calculator includes PMI in the estimate when your inputs trigger it, so you can see how a smaller down payment affects affordability.
