@Harlan Cox  Just spend the 1k get your RE license then you do not have to worry about it and expert agents in your state will teach you how to do it.. getting advice from strangers on the internet is not really that great of idea.. you can bounce things around like beach ball but remember who your talking to some stranger.

sometimes total strangers call me, because they know that I'm a buyer.

No--take away your good intentions and look at the situation as if you were a dispassionate stranger who doesn't see his Mom's money as a shortcut to his get-rich-quick real estate dreams.

To people from many other countries these institutions, normal in America, are shocking with the thought being "how could you just leave your elder family member in a facility full of strangers."  

Seems unlikely to me, but stranger things have happened.

They come online, listen to strangers to validate whatever they want to hear. 

I have never heard of any tax sale or foreclosure process that would put strangers together in ownershipbut I have heard of and am familirar with the bidding down of the statutory interest rate.its extremely common in FLA and AZ  the gurus say one can make 16 to 18% but the reality is those that know the game and are bidding on for real collateral not strips of land.. will bid down the returns into the 4 to 8% range..

Quote from @Tammy T Pimienta: When you ask for a mentor from a bunch of strangers, you're going to get people that want to sell you a program or a property.

i know your not asking this but to break the pattern, it is best for your mental health to be hands off arms length from your short term or long term tenents, weather they are 12 month lease tenants, friends relatives, sympathy to strangers, you should give to property manager or a manager who will do short term monthly rental, and separate yourself and remove emotion. ps., in florida now, you have an unlawful detainer action and there is still a due process, attorney is needed and there is no throwing someone out on your own, that is not going to happen or you'd lose alot more than you lost now. we buy properties like this and pay for the attorney.  

You could offer them a smaller amount so they can move into a rental, but I wouldn't be comfortable giving a stranger (who has money problems) that sort of money.
