can I sue for my prepaid rent and security deposit

I paid for a 4 year lease of a home there were 2 owners both had 50%. the 1 owner that rented me the property had died . that is who I had the signed lease with. The other owner had been mia for 27 years. After the owner died the other owner appeared and got full ownership for 1 year she never did any needed work on the house. then she sold the house. the new owner gave me $3000 to move out I never got my prepaid rent money back or security deposit for the prior owner. Am I entitled to that money
