Breaking a Lease during possible foreclosure
Hey everyone. I signed a lease approximately 2 months ago and shortly after moving in, I received a summons. The guy that delivered it said that I had the right to contact an attorney, including the attorney handling the case on behalf of the bank. He said I had a right to know what was going on as I'm listed on the summons as "Unknown Tenant 1 & 2" [my younger sister is on it too]. I called the attorneys and they confirmed that as far as they know, the case is still open and they have not received notice from the mortgage company that any action has been taken. I spoke to my landlord who originally told me that what is going on between the bank and her is none of my business and that I have no right to get involved. I told her to use my last month's rent [I originally paid her first, last and security] until I know exactly what is going on and then I will furnish her with whatever money is necessary [late rent, last month, whatever]. She refused that deal and agreed to furnish me with a letter from the bank on October 3rd which would confirm that everything was being handled. She now refuses to give me the letter and insists that my rent is in fact late [which she is now charging me a late fee for] and still says that I should mind my own business regarding the foreclosure. The mortgage company left a notice on my door this weekend that said to contact them immediately and also sent somebody out to take a picture of the exterior of the house [I wasn't dressed so did not get to speak to the mortgage company rep].
I've been advised that my lease is no longer valid as she put the property up for rent while it was already in the initial stages of foreclosure and I was not informed of this when I signed it. Can I legally break my lease now under these circumstances? If not, what can I do?
Edit: I'm in Miami so this would fall under Florida law FYI.
