One thing when we are house hunting - hubby is military so we have relocated a few times is that it is important to consider not being on the outskirts if possible as people have a mental block when it comes to back tracking to work so you need to find people that can come to you on their way as compared to driving to you and then driving back to where they started before driving into work. Not to say you can't attract these kinds of people but it is a lot easier to keep spaces filled if you are drawing from a larger pool of people driving your way.
