Leaves an immediate bad impression.Entry Door: This seems silly but make sure your front door opens and closes easily without the need to play around with the door. 

I know all are so used to campaign promises just being a slogan of lies but this is a factual thing, we know they are actually do what they say they will do, or at least try like hell to do it.

This is my way of not being forced to rent to the first qualifying party that gets a toe in the door.
