Because Sabino Mountain has had more than a few sales in 2009, it is fairly easily to determine fair market value of non-custom built homes:
2009 Sabino Mountain Homes Sales of non-custom homes:
4236 N Sunset Cliff Drive $323,500 2,074 square feet
4192 N Sunset Cliff Drive $370,000 2,684 square feet
4348 N Ocotillo Can Drive $375,000 2,236 square feet
4334 N Sunset Cliff Drive $380,000 2,904 square feet
4028 N Sunset Cliff Place $383,500 2,936 square feet
4338 N Ocotillo Can Drive $418,000 2,708 square feet
Of course, if there is a swimming pool or many custom upgrades, the lot is larger or with a better view, etc, there are pluses and minuses taken when compiling a market analysis to determine fair market value.
