Home(s?) Flooded in Harvey and other events being sold undisclosed of prior flooding?!

So there is a home in my neighborhood that has changed hands TWICE about flooding in the home from Harvey. First time i chalked it up to an asshole investor who didn't technically live in the home during the flood and a buyer who didn't do their due diligence. Well the home flooded in a recent high water event in Houston and the owner dipped out and the new owner, again, wasn't aware of recent flooding.

How in the f**k is this happening? Can I report this?
