Selling rental to Owner Occupants while tenants in the property

[Dave DeMarco]

Need some advise from those with experience. I am about to list my single family rental for sale. The house will most likely be sold to someone who will be an owner occupant as the numbers will not make sense to an investor. The tenants are currently on a month to month lease and I was curious about the best way to show the property (or not) with them in it and what I should expect. I want to give them ample time to find a new place and accommodate them as best I can. 

Issues:

I DO NOT want to carry the property un-occupied while finding a buyer. 

They are not the cleanest people and will need to keep the place show-able.

I have had issues with access to the property in the past, although dealing with the adult son seems to have solved this problem to a degree. 

How much notice do I give them? How much time is reasonable to a buyer to occupy?

What should I be wary of and how can I best help myself?
