Robert had fallen $14,200 behind on Hillsborough County property taxes after a series of medical emergencies. The county had issued a Notice of Tax Sale; auction was 32 days away. Florida is a tax-lien-sale state (12-18% interest), and Robert's home had been listed in the upcoming auction's published notice. He had roughly $90,000 of equity but no cash to pay the back taxes.
Tax sales in Florida give the certificate holder the right to collect back taxes + interest, and ultimately foreclose if redemption doesn't happen. Robert's options were: pay the back taxes (no cash), refinance (no time — 4-6 weeks minimum), list traditional (60-90 days, too slow), or sell cash before the auction date.
Back taxes paid in full at closing ($14,200), mortgage paid in full ($114,000), Robert received $41,300 net. The tax auction was canceled. Robert's credit was unaffected by the back-tax situation since the lien was paid before becoming a judgment.
