Florida- URGENT input needed for mom. Any suggestions?

I tried to post this from my phone, then it shut down, so please forgive repeat if it did post. Mom is 90, lives in Florida- no dementia, no Alz. Has been a raging nasty narcissist all her life. 4 Bedroom pool home, loaded with 40 years of stuffing it full. Nocturnal, incontinent, obese, wheel chair or walker required- mean mouth, vile attitude, expert at manipulation and will twist anything to anyone at any time. No friends. Now that you got this part....here we go. She up and sold the house she lives in. Signed all papers w/o my knowledge. (only child- 1500 miles away) BY OWNER! Florida uses title companies, thank God. All she can see is $$$$$$$$$$! She has no money except for SS. which totals $1400 per mo. No savings-I have no HCP, POA- there is no will or Living will. She has a passing date of June 25th, 2018- she must vacate by 6-28-2018. Contractor coming for new owner on 7-2-2018, Stock starting to be delivered on 6-29-18. She will not pack, she has no place to go to. She will not hire anyone, she will not look for place to live. She has no $$ to do this either. We are talking my pocket! She is banking on her skills to manipulate and using age and figuring on twisting the new owners into doing everything on her time frame. She says nasty things like- "This is MY house til I am out this door". " I get what I want, you'll see-". I leave here on MY TERMS! I've warned her, there will be legal problems- she says she's 90 and no ones throwing her out. AND if there is a law suit, then it's MY PROBLEM! I've told her I can come down there and we are moving you out and finding a place for you there. She refuses. She said she will not let me in the door and will call the police if I try anything. With no PCP or POA I'm screwed! She sucked the new owners in but good. She comes across as the sweetest poor sick little ole lady, whose rotten daughter abandoned her. She told them my husband is a drunk- she told them my son is "nothing like them" ( he won't take her calls) and lets not get started on what she says about my daughter- too vulgar to type. The buyers told me the woman they met is not the woman they are now dealing with! They are stunned, scared and just horrified of what they have gotten themself into. Their son is autistic and the wife is a breast cancer patient, Thank God, doing well and almost done with it. They have no place to go soon either! They are legit, good honest people. I can not tell you the LIST of things she had them do for her already. She is playing with these people! She knows what she is going, she even says so out loud! They have finally figured it out and are sick to their stomachs as well and have turned to me for help. She got all of us but good this time- I could type until the world ran out of time telling stories of the crap this woman has rained down upon this earth and anyone who direction she looks in. Everyone is a moving target. Please anyone out there....help, suggest, anything you got. I have no legal standing, I am sick to my stomach ( nothing stays in or down) Im up and down all night- my brain is bouncing. She has pulled her best stunt ever-this woman is 90! If I say to her where are you going to live, I get nasty answers- shut up, what do you care. She will not look for housing, she will not pack. She will not allow me to get movers, she will not allow me to get housing. She is however, trying to force me into taking her to Mass. and live with me. She told me to close my business- she expect my full time and attention. This will not happen, but how do I get her out of that house! Where do I put her when I do? You have no idea what a maniac she is and the ends she will go to- the nightmares she has caused, and these arent cheap either! Just to let you know one...she had a roof put on her house. NO WARNING she was doing this.... The guy trusted the sweet lil ole lady, the day they came to do the roof- she said I was out of town over night and forgot to leave the check for deposit. He did the roof, my phone rang and I went 10K in debt on cr card. THE CONTRACT WAS IN MY NAME. She used my name!!! I could have left this guy in a lerch, but I wont do that. He did a good job, inspectors passed it, place was left immaculate and he was well known and does excellent work w/o complaints. Im still paying at 27%! So ya, this is her grand finally- please help.
