Clearly I didn't perform due diligence here...although the Control Map and Parcel number were listed correctly, and a surveyor re-walked the property (a vacant lot, ~1 acre in size) & provided me a copy before closing, I only walked the neighboring lot, under the impression that it was the one, since the realtor's sign was ~100 yards away from the correct one.
Moreover, the lot I purchased has overhead power lines running straight through the middle of the property, and their regulations (as a subsidiary of a federal utility Authority) state that easements are 15' to either side of the lines...rendering my new lot practically useless for building a residence.
When I first saw the lot listing on Redfin, there was not a mention of power lines in the description. When I used Street View on Google Maps at the front edge of where it showed the lot boundary, there was indeed power lines. So I called the realtor and asked, to which she replied "not that I'm aware of."
It's worth mentioning that this is in a fairly-rural area, and people I've talked with who live nearby have said that they ran into confusing aspects of where their actual lot was as well. Also, a person who has a house on the lot behind mine stated that the requirements for a building permit from the county have recently changed for that area, due to more frequent rockslides.
We closed on this lot less than 30 days ago. Would it be useful to file a formal rescission? Or, do I have any valid basis to sue
