Cue IASIP theme song 
The Gang Sells a House
The article should be saying some poor folks thought they were buying a home only to find out they were being scammed by some impersonators, this article makes it sound like the actual owners no longer have their home and if that’s the case then that’s f-ed up, laws should exist to not let that be the case. >

Isn't this what title insurance is for? >

Do you mean the ‘buyers’ should have to give the house back, and might be compensated if they had title insurance?
Or that the original owners should need insurance against this sort of fraud, and that if they didn’t have insurance they should just lose their house? >

The buyers get screwed. Owners get their house back.
