Solutions that the seller can take to avoid a tax foreclosure

Hey guys, this will be my first wholesaling deal. I am literally in a sticky situation with the seller because she owes some back taxes on her property. The thing is, she has until the 2nd of July to pay her back taxes, and if she is unable to pay by July 2nd, she will have to file for tax bankruptcy. I was wondering if you guys have any solutions to avoid the mess of having her file for tax bankruptcy? By the way, she owes $16,000 in back taxes.

Also, the seller wants me to set the closing date on the contract to June 28th instead of our original closing date, which was August 17th, because she wants to receive the money in a timely manner to pay her back taxes. Another thing she told me was that she would like to stay an extra 30 days after the closing date, meaning that she would like to move out on the 28th of July.

Any thoughts and suggestions as I navigate what seems to be an obstacle as a new wholesaler?
