Tell us the address, the condition of the house, and what the notice says about the mortgage sale. You do not need to repair, clean, or empty the house to ask about a sale.
Written offer and written terms before you commit; title-company closing.
If you choose to move ahead, the title company reviews the property record and works through the lender payoff and other amounts needed for closing. A current payoff and the actual sale date matter; the written offer does not change either one by itself.
You don't need to pay off your back taxes before we settle. We buy houses with back taxes and liens — payoffs get handled through the closing, not by you upfront. When you sell to us, we pay the closing costs, including Alabama's deed tax. Your mortgage, liens, back taxes, and share of current property taxes are separate.
