Horder ?

[Shaun Lapsley]

I have been looking for my first property to buy and hold. 
I viewed a property today that was in great shape.
What I was able to see of it anyways.
New roof. Very well done remodel of the upper unit (2bd 1bath) (vacant)
Lower is the issue.
Without going into details I would label this person as a horder.
My agent is getting us a walk through of the lower unit asap.
I havent actually been through the unit, but the basement, the garage, what is visible from the outside. All signs of a horder. pack rat. nester. whatever you would like to call it.

Has anyone ever dealt with this ? Would it be possible to require the property to be vacant at the end of close or any other advice ?
