The insurance and mortgage companies should have been interested in the information but I doubt whoever had the information would have thought to contact them and, even if they did, I doubt the companies would have had a reliable process for receiving and investigating that sort of “whistleblower” claim. It’s even more complicated when it’s a condo building and there are any number of different banks and insurers involved, rather than just one. Everyone assumes someone else is looking at X and so they all ignore it a bit more than they should.

But, if you’re looking for the business niche, I’d guess they’d be your customers. Basically a “bug bounty” program for underwriters of tenancy in common real estate.

The SEC does.

They’re called qui tam suits[1] and in the US they’re commonly brought under the False Claims Act[2] which can apply to any government contractor but Medicare Fraud is a big piece. The way it works is the “whistleblower” files a civil suit with the allegations and then the government can choose whether or not they want to take over the case. If the government think your allegations are solid and the potential recovery is worth their while they’ll take the case and you’re entitled to 10% of anything they ultimately recover. If, for whatever reason, the government decides not to get involved, you can continue the case on your own (but kind of on behalf of the government... it’s a bit weird how it works) and anything you recover goes to the government but you get 30% for your trouble.

The SEC also has a whistleblower program that another commenter has linked and, as of recently, they have really been paying out a lot of money to whistleblowers. Larger sums and more frequent payouts than we’ve ever seen before.

Yeah, a Code Enforcement department for a large municipality would pay for reporting automation. I don’t think it would prevent this event. It’s a condo, so the building is probably maintained by a POA. Who would have an incentive to inspect the building? Who has a contractual obligation for maintenance? POA members. Who has to pay for repairs? POA members. Who now has an incentive to avoid repairs? POA members. Would you dime yourself out to be on the hook for repairs that may exhaust your discretionary income for many, many years? Or would you “touch up the X-ray” as Warren Buffet put it?

POAs are a terrible idea and I wish they didn’t exist. Distributed ownership always seems to incentivize bad behavior.
