Costs of owning and selling in Alameda County

Property tax (Prop 13)

The base levy is 1% of assessed value. The assessed value is reset to the purchase price when a home sells, and after that it can rise by no more than 2% a year. Voter-approved bonds and local levies are added on top, so check the actual tax bill for the address. California State Board of Equalization: California Property Tax, An Overview.

Supplemental tax bill

After a purchase the county issues a supplemental bill for the difference between the old and new assessed value, separate from the regular bill and usually not paid through the mortgage escrow account. California State Board of Equalization: supplemental assessments.

Mello-Roos and special taxes

Many newer communities sit in Community Facilities Districts that levy a special tax, shown on the property tax bill. Sellers must disclose it; ask for the amount and how many years it runs. Mello-Roos Community Facilities Act, Government Code §53311.

Documentary transfer tax

Counties may charge $1.10 per $1,000 of the sale price when a property changes hands, and some cities add their own. The escrow company calculates it; who pays is negotiable. California Revenue and Taxation Code §11911.

Insurance is the other big cost: several insurers have stopped writing new policies in parts of California, and some owners in Alameda County rely on the state California FAIR Plan (California Department of Insurance). Get an insurance quote before you remove your contingencies.
