On the show Property Wars, they always say that the bidders cannot
look into the house. They show that the windows are covered.

Johnny, yes, it’s the law. The bidders don’t own the houses yet, nor
does the bank. Until the auction takes place and a trustee’s deed is
granted to the highest bidder the property belongs to the homeowner.
To enter the house without the owner’s permission is trespassing.

This is similar to what happens on storage wars.

I've often wondered why, when a storage locker goes abandoned (unpaid),
that the storage company doesn't automatically get ownership of the
contents, to do what-ever they like with the contents, to open the
locker, rummage through the stuff, take what's valuable for themselves,
or put it up for sale themselves, throw away what-ever they want, clean
the locker out and make it available for the next customer to rent.

But for some reason it doesn't work that way for storage lockers, and
(apparently) also not for homes that have been forclosed on - but still
have people living in them?
