Found Note for Sale (2006), house sold recently(2015), good/bad?

[Joseph Blauwiekel]

Doing some note research online tonight and I found a couple decent buys.  Cheap 2nd, good equity, taxes paid BUT on two occasions the notes I found were originated around 2006 and the house has sold recently (2015ish).  I imagine there are a hundred steps in between but isn't this what title insurance is supposed to cover for the new homeowners? Assuming they got title insurance, would the insurance policy pay off my note if I bought it and came forward?

I anticipate this being a real can of worms. Thoughts? Thank you. Looking to get my first NPN here soon.
