Property tax on typical home values in Solano County
| Assessed value | Primary residence (with exemption) | Rental or second home | Each installment (residence) |

At 1.179%, the $7,000 homeowners' exemption saves $83 a year. Prop 13 lets a home's assessed value rise by no more than 2% a year until it sells or is newly built on, so owners who bought years ago usually pay on far less than market value.
