Interestingly enough, houses over a million fared the best last year. In fact the number of sales increased and these high-end houses appreciated! The two prime Foothills zip codes –85718 and 85750– proved to be the best investments. Houses over a million in the 85718 zip code had a 18% increase in number of sales and the 85750 zip code had a 40% increase in the number of sales. The average cost per square foot went up 9% in the 85718 zip code and went up 6% in the 85750 zip code. The average days on the market were a little longer, but really only went up to a little over 3 months, and this is not a long time when selling a high end home compared to the past. Without a doubt, many people made huge gains in only a few years time and this appreciation is expected to continue in 2007. In 2006 the highest price house in the 85718 zip code was located in Pima Canyon and it sold for $3,100,000; the year before Pima Canyon also had the highest price house and it was even higher, at $3,600.00. In 2006 the highest price house in the 85750 zip code was located in Ventana Canyon and it sold for $2,950,000; the highest price house in 2005 was located at Rattlesnake Canyon Estates and it was priced at $3,650,000–it has a remarkable 49.12 acre homesite.
