the 1 story house across the street from 242 E Croydon Park Rd Tucson AZ 85704 sold for $347,000

This quality home, like all in the Miramonte By The River gated development, are designed and newly constructed for high energy efficiency and designated as "TEP"Tucson Electric Power Homes.  TEP engineers inspect and test these homes repeatedly during construction to assure that they meet rigid energy efficiency requirements that are rewarded with  low power rate guarantees. Miramonte homes are fitted with efficient 13 seer heat pumps, insullated windows, built up reflective roofs and energy star appliances.
None of the neary homes outside the gates and perimeter walls of the Miramonte development are energy efficient TEP homes.  None were inspected and tested during construction.
The subvision immediately north of Miramonte homes on Cedarvale Rd and Castlefield Circle was built in the 1950's and are highly inefficient in design and construction materials. 
They were built in an era when energy efficiency was not a consideration.  Most of these homes have leaky, single panel windows, no sidewall insullation, minimal ceiling insullation and cost a small fortune to heat and cool.  Almost all are devoid of air conditioning and rely on swamp coolers for minimal relief on 104 degree summer days..
No reliable or reasonable appraiser would use these outmoded homes as a comparable when valuing a TEP home.
