One of the essential things to check when buying a home in California is the property tax.

The basic property tax rate in California is fixed at 1% of the assessed value according to state law (Proposition 13, 1978). Once purchased, it can only increase by a maximum of 2% per year based on inflation, meaning the longer you hold it, the lower your tax burden remains.

In San Bernardino County, where Rancho Cucamonga is located, the county tax rate adds to the basic 1%. Additionally, local Mello-Roos Community Facility Districts (CFDs), school district debt repayment taxes, and special assessments can increase the effective tax rate, which varies by address.

The Etiwanda (91739) area is a developing district, so several Mello-Roos CFDs are established. In this case, in addition to the basic 1%, annual CFD taxes can range from hundreds to thousands of dollars, so it is crucial to check the Mello-Roos status of the property before purchasing.

For the Etiwanda school district, a separate bond repayment tax is imposed for new school construction and renovations. In contrast, established residential areas like Alta Loma, developed in the 1970s and 80s, often do not have CFDs, resulting in a relatively lower effective tax rate. The effective tax rate typically ranges from 1.1% to 1.8%, with newer developments closer to the upper end.

Property tax bills are issued twice a year (in November and February). The first installment due on November 1 must be paid by December 10, and the second installment due on February 1 must be paid by April 10; late payments incur a 10% penalty. The most convenient way to pay is online through the San Bernardino County Tax Collector's website.

When you buy a new home, the county reassesses the transaction price as the new assessed value, so the taxes for existing residents and what you will owe can be entirely different. It is common to set up automatic monthly payments through a mortgage escrow account, where the bank pays the taxes twice a year on your behalf.

If you are a new buyer, it is recommended to confirm the exact Mello-Roos applicability and the estimated total annual tax amount for the address with your real estate agent or escrow company in advance.
