oops. I realize now that you said feet^2 and not price as your criteria. Even so, I think you can just adjust the price range to find what you need. $1 per square foot is a fairly decent estimate of expected rent anyway. You’ll just find that the newer it is, the higher this number will be.
Do be careful though, as there are some folks out there who are trying to fetch way too much for their place. For example, a new 3000 feet^2 (I like that) home for $4000 or more. These are just people who are trying to get you to pay their mortgage for them–don’t do it!
