have you thought of a unit? they can be relativly mantnance free outside?

the realestate usualy (as far as i know) look over your app, put threw the ones were they think to the owner who then has the final say. i know some agents hold onto apps untill there is a decent number then put it threw to the owners. i would give them a call to see how things are going and how long to expect a reply, it also shows that you are interested itms?
