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.
The title company reviews ownership and recorded claims for the sale. The creditor or tax office supplies the current amount and payment or release instructions. Any agreed payoff is included in the settlement figures and handled through closing. Your final proceeds depend on the written offer, confirmed balances, and other closing items.
A lien is a claim that may need to be addressed in the title and closing work. A payoff statement gives the current amount and the instructions for satisfying the debt as of a stated date. A record search can help identify documents, but it is not itself a current payoff quote.
