Under Proposition 13, the assessment year 1975-76 serves as the original base year. Thereafter, any assessment year in which real property, or a portion thereof, is purchased, is newly constructed or changes in ownership shall become the base year used in determining the full value for such real property, or a portion thereof.
A comparable sale is a property that sold not more than 90 days after the subject property (your property) in the subject's property neighborhood (same school district or close proximity). The comparable sale should have features that are similar to subject property including size, number of bedrooms and bathrooms, quality of structure, condition and lot size.
If you are providing comparable sales in support of Decline in Value (Proposition 8) then the comparable sale needs to have occurred prior to April 1 for the tax year in question, i.e., for 2010-2011 Secured Bill Tax Year you would provide comparable sales through March 31, 2010
