How will the Datamontic Value Estimator help me?

California Prop 8 allows for a reduction in property taxes when the market value of your home is less than the taxed value. To obtain this reduction, you need to complete an application called the ‘decline in value’ application. In order for you to complete the application, you need to show two comparable properties that sold for less than your home’s tax value.


Datamontic will analyze your home and generate the Datamontic Value Estimator report. This report will include two comparable properties that sold recently and a detailed comparison with your home. The report will also provide an estimate of your home’s tax value based on these recent sales (click here to see a sample report). Once you have the Datamontic Value Estimator report, you can use it to complete the ‘decline in value’ application.


What is a Decline in Value application?

You can use the 'decline in value' application to claim a reduction in property taxes should the market value of your home fall below the taxed value. The ‘decline in value’ application is a one-page application that can be completed online or by mail. All real properties including single family, condo’s, apartments, etc., are eligible to file. The deadline for filing in Los Angeles County is November 30, 2019.
