California Home Affordability

The data below quantifies California home affordability by using home prices and home price indices to calculate price-to-income and price-to-rent ratios.1 The maximum affordable loan amount for the median household income is also calculated. You can also compare California home affordability to other states.

California Home Price-to-Income Ratios

The home price-to-income ratio for California comes from the Federal Housing Finance Agency's relatively new state median price series and their purchase only index combined with California annual median household income data. The FHFA home price series yields a dollar ratio (top chart) while the index results in an index ratio (bottom chart). Based on the latest FHFA state home prices in June 2010, the price-to-income ratio for California was 6.06.

California Home Price-to-Rent Ratios

The price-to-rent ratio for California is determined for both the FHFA median price and the purchase only index by calculating a ratio with the median contract rent. The price-to-adjusted rent value takes into account CPS reported household size to attempt to correct for quality differences in renter and owner occupied homes. More on that process here. Again, the median price ratio is a dollar ratio and the HPI ratio is an index ratio defined to be 100 in Q1 2000. The adjusted price-to-rent ratio for California was 24.94 in June 2010.
