re: kicking out tenants after buying a house

Haven't looked at this issue in years, but 15 (or so) years ago, the lease had to be filed before the closing date of the sale to bind the new owner, i.e., the new owner had to have notice that the property was encumbered by a lease. If the lease was recorded before the closing, the new owner was bound to the lease. Also, on closing, the old owner was required to transfer any security deposits to the new owner at closing.
