Frequently Asked Questions

What is a mill rate in property taxes?▼

A mill rate represents the amount of tax payable per dollar of the assessed value of a property. One mill equals one-tenth of a cent, or $1 in tax for every $1,000 of assessed value.

What is a Homestead Exemption?▼

A Homestead Exemption is a statutory tax relief program that shields a dollar portion of your primary home's value from property taxes and caps annual assessment increases.

How do property taxes affect my monthly mortgage payment?▼

Most lenders collect 1/12th of your annual property tax bill each month in an escrow impound account and pay the county on your behalf when taxes are due.

Can I appeal my property tax assessment?▼

Yes. Homeowners can appeal assessed valuations through their local county Board of Equalization by presenting recent comparable sales data.
