Yeah, I am a lawyer, and I have done some probate work in the past, and there is more to this than what people are suggesting here, particularly considering the new laws that were passed.It sounds like in 2007 when your father passed away, someone made the ill choice of not probating the estate (your mother most likely got the house by operation of law, not the children).  

That's up to you as to whether you want to accommodate his request but Florida Landlord-Tenant Law is very clear:  "Except in cases of emergency, landlords who want to enter rental property in Florida for needed inspection and repairs after giving tenants 12 hours' notice of their intent to enter (unless the tenant agrees to a shorter time), and must enter only at reasonable times (defined as between 7:30am and 8:00 pm)."

"I am too busy, daughter is ill(always at rent time), I have an emergency.

Being successful (in most pursuits) is a matter of simple/intentional/consistent actions over long periods time.

I was thinking of house hacking (if I can find a place with 2bds +) OR the 2 realtors I spoke to mentioned I could put the bills in my name and rent to someone I know  or possibly Airbnb (though they did mention it does go against terms of the loan for first time buyers to rent it out right away , but that as long as I have the 'intention' I should be ok.

Next, they booked the guest from hell who was intent on getting a free stay from the get go.  

There are items however where active concealment by a seller with "intent to fraud" would still make a seller liable but there is a high level of proof needed in court for that.Either way this should have been planned for better.

Ill have to report back if I eventually experiment with that.I did operate one large house in Flagstaff, very close to the ski mountain road and incredible mountain views.

If you give a little more information on your intent, might be able to point you in the correct direction.

I don 't think Zillow's publishing of inaccurate information justifies your intentional misinformation.
