If not legally abandoned, you will have to either get them to surrender possession (preferably in writing, but not required) or you will have to get an ejectment order from a court. 

If this option is chosen, the Tenant(s) agree to surrender the Premises in move in ready, fully cleaned condition.

MLS represented myself , there were multiple offers on this house ( cash offers & Higher ) my strategy was i offered $1000 over ask and surrender my commission and inspection was informational only.

Not sure if this helps or not, but in most states you can surrender the title, declare it to be permanently affixed to the land, and it becomes real property and no longer a mobile home. 

So if you can cash flow more that a 5% on your annuity then it may be worth losing the 6500 in surrender charges.  

BE SURE to get a Surrender Statement signed by both parties - - "on this date, Joe & Mary Doe surrendered tenancy at 123 street, town, state in exchange for the keys, Mr LL return the deposit of $123.00 "

I have offered as much as 1/2 of the deposit in cash for the exchange of the keys and a written surrender document noting details, date and signed by all parties.Either approach cost me money - - about the same too.Cash For Keys saves me time and I get it rented quickly, thus avoiding future lost rents awaiting the court judgment and the sheriff.Which is a better BUSINESS decision to you?

Owning only one REI, I found it costs more than it was worth.First, I already had liability insurance and added a general Umbrella policy on top of that.Second, in 19yrs of self-managment, I only had one trivial claim of 5k (which the insurance co & I believed to be extortion and too much to bother fighting) so we just wrote it off.After 5yrs, I surrendered both the S-corp and the LLC

get another contractor's bid before you surrender.

Before I commit to surrendering all of my investing capital, I will certainly re-evaluate the comps to ensure the equity is/will be there.Regards,
