this actually happened with the obama administration years ago.these are what you are finding, troy. these houses are less than desirable and the bank, well frankly, " has bigger fish to fry". so these houses sit and sit and sit. get run down, and pretty soon, when the bank wakes up and realizes they have thousands of dollars in carrying costs invested in this house, they discover that they will never get anywhere near the amount that they have invested in the house back to them, so they " drop" the house. thats right, they write it off. they stop paying someone to check on it every 2 weeks, they stop paying someone to mow the lawn, etc. and they stop paying the taxes.my advice to you, call and ask the bank if they have " released the lien or mortgage" back to the original owner. some banks will tell you, others will not. then, call the local tax authority. ask how many years ago the last taxes were paid on the house and who paid them. if it was a bank, and they stopped paying the taxes, well, there is your first sign that the bank has dropped the house. they aren't going to keep paying the taxes on a house that they no longer want, are they?

Can you not write something legally into lease agreement terms that states the tenant must vacate a property after 30 days past due?

@Erick Harbert  you should actually talk with a securities attorney... there are a lot of rules and its much more complicated than just writing an agreement and getting insurance.and putting partners names on deeds is probably not what you want either. 

I've heard conflicting info from CPAs and consider you credible from what I've read of your writing.

Every three or six months there's magically a seasoned 25% down plus needed PITI reserves, ready for the next purchase, sitting in a plain old boring Wells Fargo checking account without a lot of activity on those two months of bank statements I ask for.They write offers that end in 888, or want me to tweak their loan amount down so the base loan amount is $XXX,888.

I'm sure we'll sign a promissory note, but who writes that up?

Have you ever played an RPG where you get to allocate talent/stat points?

Should I write a letter and mail it to the house hoping they have relatives who will read it. 

Also, get everything in writing....Verbal agreements are as good as the paper they're written on :)
