I had one with 409 exceptions…..It was about a 600 acre lot about a mile from a state road down a truly abandoned county road. Came to find out the county didn’t want to maintain the road and abandoned it while a shady developer was trying to subdivide the parcel (beautiful property with a 30-40 acre private lake). So Shady developer started by selling 30×30 camping lots (20 blocks with 20 camping lots per block) some officially recorded and others just by private conveyance….Then shady got cocky and sold 9 real acre plus lots….and finally got busted when when of those lot owners applied for a building permit. Shady LLC went bankrupt and disappeared, the lot owners mainly deeded their pieces back to the bank, gave them to the town (town never tax auctioned them for some strange reason), and I think 7 lots were still owned….2 of the real private lots and 5 of the camp lots. Luckily Shady refinanced once the camp lots were sold off and had a map that was part of the loan paperwork that showed were they were roughly. The real lots were all deeded and didn’t show up on tax mapping, but did show up in the title report.
The crazy part is the PLS said we had to find the camp lots (at this point were only accessible by a couple mile hike for the owners) which we did and people were actually there camping on the lots (summertime). As I recall we were doing an ALTA on the property and it was being sold to a land conservancy for $200-300K and the town was giving their lots to conservancy. We actually watched the process in case it fell through because we were going to band to together and buy it if the deal feel through. No luck on that.
