Return contains the average cost per square foot of that area, and whatever else you want to throw in. :)May 02 2008 - US33YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
