Prices on homes with Fannie or Freddie mortgages are on the rise nationwide. Arizona is one of four states, plus the District of Columbia, where prices have risen the most.

Nationwide, homes with Fannie Mae or Freddie Mac mortgages are up in price 6.5 percent  in the third quarter of this year, compared with the third quarter last year.

According to the Federal Housing Finance Agency, which measures home prices with Fannie and Freddie loans, prices in all 50 states and the District of Columbia are up over the same period.

Washington, Hawaii and Arizona are up the most, with prices rising ten percent or more. Washington, D.C., had the highest increase at 11.6 percent.

The home price index is calculated using home sales price information from mortgages sold to, or guaranteed by, Fannie Mae and Freddie Mac — and excludes high-end homes bought with jumbo loans or cash sales.
