Yep, I have a good friend that ran into this issue on his home he bought 20 years ago. After 5 years of living in the home and making payments on it, it was finally discovered that there was no clear title to the property going back 60 years…
It took another 2 years to clean it all up, but it required the township, county, and a state agency to get involved to make a couple of problems “just go away”.
