NOT in any way saying you are.. but you get the point I am sure.. your tenants are your life blood so keeping them happy is more important than letting buyers who are not even in contract into the houses just to look around not like it and not buy it.If the home is vacant I suspect they are Leary of squatters and thieves and or they have been burned by wholesalers and their lies about having their partner look at the house.. which is really not their partner but is potential buyers.. very slimy how they do that.

I suspect that it will2.
