@Orlando Paz  In most states a Mobile Home is considered a Motor Vehicle and has a title that is identical to a Vehicle so they are easy to transfer ownership, but counties will tax the MH annually.  

Question 2 - What is the proper way to transfer the security deposit to a new account?

The release will also keep you out of trying to double close in our state, we have horrific transfer taxes.To your successJosh

Its just a normal purchase, nothing too complicated.The complications are than the bank will insist on using their title company if you want them to pay for title insurance, they will have a big stack of addendums, the property is often transferred with some form of deed that's less than a general warranty deed, and the bank will generally not do any repairs. 

As all three of us here have said, there are so many variables, that if you feel you do want to give it a shot, realize we are doing 100% of the work to finding them, peeling back the onion, getting them transferred to the new servicer, checking for missing assignments & such, starting and completing a workout process, selling the note or property, and ultimately making a profit.

@Milton JohnsonI'm also Active, stationed Conus though and have been developing a strategy that will work for me, very difficult as I know' I'll be transferring somewhere next year, hoping for Cleveland, but still am not certain.

Those can be 3 different issues and sometimes conflicting issues.Here to transfer from personal name to LLC will cost 2-5% transfer taxes and some smaller recording fees. 

However in Baltimore city they will not allow it because they want to collect the transfer taxes on the property twice. 

My question is this: if the deed is transferred to my name, is it at that point when I can list the property on the MLS?

If there is no money coming to the heirs, I'm not sure it's in their best interest to transfer that liability to themselves.
