None of this "we don't disturb our tenants with Buyer inspection" BS line you hear sometimes.  

Do you think the possible mentally disturbed man is your tenant?

     Our nicer houses have TVs in every room, or darn close (a 8-10 bedroom house we may neglect 1 or 2 small bedrooms where even hanging them on the wall makes the room feel smaller, these smaller rooms are only used for sleeping). 

Seller will not let me see the inside of the property, to "not disturb the tenants".

If the numbers still work then lay your head down at night and sleep peacefully. 

I would have also negotiated that the foundation repairs be done before closing and that any repairs resulting from the disturbance be negotiated at the time of repair or just covered by the seller.

Sheriffs office showed up to avoid any disturbance, changed the locks, did a quick inspection and gave them back their deposit.

You also risk waking a sleeping giant.

So easy for the younger folks to just rent a room go home to sleep a bit but work eat and socialize on the campus as well as other amenities.Also I not positive but i think if you work for a CA company and move to another state you still pay CA income tax. 

Imagine one tenant likes to sleep cold and the other hot.
