They are threatening with unreasonable demands such as, give me the money now and I will vacate later else I will cut loose and create havoc.What are your thoughts?

Address doesn't get changed or forwarded or enough time passes the PO will not forward anymore....so no one gets the notices, and it goes to foreclosure.The % is probably really c/o or should be, but they don't have a key for that so use % and that means "in care of" .Let's say dad moves in with the kids, the bill gets addressed to dad c/o Dwayne Wade at the new address.

but to be frank i never used it since we get date downs on the phone and TRIOS e mailed to us while we are on the phone.. a TRIO in our market is the picture of the assessors page.. lots of info.. copy of last recorded deed  how they took title.. and a plat map.. this was key to us.. since all i needed was the last recorded deed and I could do my own warrnety deeds in house.. the deed had the legals.. and current vesting.. so you just did a deed from current owner to my company takes less than 5 minutes to prep.. get them to a notary and walk it into the recorders office.. thats how we did most of our deals as there was never time to get title insurance.. now to be fair one off investors may have trouble taking title this way when they go to resell.. but we have our relationships so they were good insuring our purchases.. but do be careful trying this yourself.. especially hand written deeds..

Plus, your tenants are paying you a lot of money, so they deserve to be taken care of.
