Arizona Home Price-to-Rent Ratios

The price-to-rent ratio for Arizona 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 Arizona was 17.49 in June 2010.
