You posted the year you bought it, and the sales price. With MLS access, a realtor can enter your zip code, the year you bought the home, and the price and it is easy to find the home. Once the home is found one can use Realist to look up the mortgages that have been recorded.
So my personal read is yes there are alot of jerks out there. However note that ANYONE can go to county records and look up recorded notes on ANY property they want in the county. In this case I do think you are okay.
