Homeowners Age 55+ (Proposition 60/ Proposition 90)
Proposition 60 (Prop 60) allows homeowners who are 55 years of age or older to sell their primary residence and transfer the base year value of that property to a replacement residence. If you sell your home and purchase a replacement home of equal or lesser value, and meet all the qualifying conditions, you may qualify for this one time transfer. This provides property tax relief for seniors by preventing a tax increase if they sell their existing home and buy another home of equal or lesser value. You have 2 years from the date that you sell your original residence to purchase or construct a replacement residence.
Learn more about transferring base year value to a replacement residence at the California State Board of Equalization website.
