Our management can't be reached, the building is undergoing foreclosure. A new receiver appointed by court showed up at our door demanding to pay rent to him. Because he was threatening us with eviction we paid, even though this month was our last month in the current lease and was paid in full to the previous landlord. Now, the receiver is telling us that we have to get back our security deposit from old management (which appears doesn't exist anymore) and claiming that when we move out our last month will be free. Although it's not mentioned anywhere in the new lease. What should we do, we have a feeling we are being ripped off two months rent which equals $8,000. Please advise on further actions.
