Call the attorney's office that did the foreclosure if you're not sure who owns your property. You should have been served notice when the foreclosure auction was held. That attorney should be able to instruct you where to send your rental payments. The lender may also offer you "cash for keys" and give you a few thousand dollars to move.
DO NOT just send it to the association unless there is a court order requiring you to pay the association. Some unscrupulous attorneys for associations may send threatening letters to attempt to get you to pay them the money. If you do, you may also have to pay the bank who now owns the property or face eviction.
You should contact an attorney because we can't give you the best legal advice.
good luck in working things out
