Renting without a lease agreement and landlord is heading for foreclosure. How can I get my deposit back?

My lease agreement ran out a year ago. After the twelfth month, I continued to pay my rent as per the guidance of the real estate agent that found this house for me. As I have been hoping to purchase a home in the near future, I didn't mind having a month-to-month agreement, but I am still probably 9 months out. I have just began receiving letters stating "It's not too late to save your home" as well as attorney letters from the home owners ociation. I provided the landlord with first month plus one month security deposit when I moved in back in July of 2007. Is there anything I can do in an attempt to get my security deposit back? Do I have any recourse? Does anyone have a website that can ist me with this situation? Any advice is welcome. Thank you in advance for your help. Sarasota, Florida Renter
