The legal possession of the premises has not been rendered back to you.

Underwriters will take that as holy writ after the suit is put to bed.Adverse Possession (AP). 

@Michael Breedlove handling management and sales in the metro area, my experience is like Nathan G. regarding the notice to vacate, give written notice and keep it short, no apologies needed. you simply want possession of your unit.

I got possession and started work immediately.

You can't always evict for possession if a tenant breaks a lease. 

Usually when you are seeing those Notices and winterization stickers the bank already has taken possession of the property.

POSSESSION: Possession of the property and occupancy (tenants excepted), with all keys and garage door openers, will be delivered to the Buyer when title transfers.

Whatever rights the grantor, the person you're likely buying the property from, possesses at the time the deed is delivered are conveyed to the grantee, you. 

Sheriff arrives and husband and another party are now in possession.  

I like bidding on ones that the bank or HUD have had possession of for 4-6 months.
