@Jessica Zolotorofe the survey was in the exception section of the title commitment, however this is what my title attorney friend said was intended for minor encroachments, not for selling the entire wrong parcel.
@Mindy Jensen - Yes it is a very interesting riddle, I find it very intriguing even though I may have my butt in a sling :) If I wind up with 3.5 acres and a pole barn I guess I didn't get such a deal as I thought but still not too far off actual value for a buildable lot with a good sized pole barn. I will for sure report back as this unfolds.
@Tyler Sterns Yes the original owner of the parcel I now own is the current owner of the other lots, about 80 years old and unknown mental / physical condition. I am hesitant to reach out to them until I know what my options are with Title Co, Listing Realtor, Freddie, etc. that will help me know how to approach this.
Years ago at a bank job we foreclosed on the wrong parcel, but we found out before we sold it and reached out to the former owner and offered 1000 bucks for a DIL of foreclosure. worked out just fine; but we DID originally mortgage the correct parcels, which in this case didn't happen.
Trying to find the bright side - with no heat in the house and being in Northern MI I really wasn't too excited about working on this all winter long, supposed to be a high of 5 degrees next week!
