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. Use this state mortgage calculator to combine that assumption with principal, interest, insurance, and PMI, then drill into county or city pages when you have a specific address.
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. Use this state mortgage calculator to combine that assumption with principal, interest, insurance, and PMI, then drill into county or city pages when you have a specific address.
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. Use this state mortgage calculator to combine that assumption with principal, interest, insurance, and PMI, then drill into county or city pages when you have a specific address.
What is a sample California PITI on $400,000?
With 20% down at 6.5% for 30 years, principal and interest are about $2,023. At ~1.00% statewide property-tax planning rate, monthly escrow is about $333; with $100 insurance, estimated PITI is about $2,456 without PMI. Drill into county or city calculators for address-level millage.
What makes Santa Clara County tax estimates different?
The countywide average reflects local voter-approved ad valorem levies on top of California's 1% base. A specific home's bill still depends on the tax-rate area and direct charges. Use this county mortgage calculator to combine that local assumption with principal, interest, insurance, and PMI so your monthly PITI estimate is closer to a full housing payment before you talk to a lender.
What property tax rate does the Santa Clara County mortgage calculator use?
Santa Clara County uses a local planning benchmark of about 1.19% on this page. On a $400,000 home that is roughly $4,772 per year or $398 per month in escrow before exemptions or special districts. Parcel bills can still differ—verify the levy code on the address you are buying.
What is a sample Santa Clara County PITI on $400,000?
With 20% down at 6.5% for 30 years, principal and interest are about $2,023. At ~1.19% property tax, monthly escrow is about $398; with $100 insurance, estimated PITI is about $2,521 without PMI. Enter your real price and down payment above to resize the estimate, including PMI if you put less than 20% down.
Why can Santa Clara County tax bills exceed Proposition 13's 1% base?
California's 1% Prop 13 levy is only the general base. Santa Clara County's ~1.19% BOE-style planning average includes voter-approved debt and other ad valorem layers, while parcel bills can add direct assessments. Confirm the parcel before locking escrow. Use this county mortgage calculator to combine that local assumption with principal, interest, insurance, and PMI so your monthly PITI estimate is closer to a full housing payment before you talk to a lender.
