The Washington Post splashes an investigative story about the tax lien business, in which outsiders buy up delinquent municipal property tax liens sometimes amounting to mere hundreds of dollars, then roll in lawyers’ fees and costs that can push up the bill into many thousands, eventuating in the foreclosure of family homes. The narrative is less than clear about exactly how the process works, and even leaves the impression that a tax lien purchaser owed, say, $6,000 can walk away with all the proceeds from the foreclosure of a $197,000 house without having to hand any of it over to mortgage holders, let alone the original owner. And some of the solutions offered (let’s not allow lien foreclosures on elderly people!) would have unintended consequences that are also, to be polite, underexplained. Still, enough of the story is there that an important general principle comes through: it’s dangerous for the law to put opportunistic actors in a position to run up $450/hour legal fees pursuing adversarial process that might not actually have been needed to vindicate their interests.
