An agent in our office had a lot listed in the neighboring community to the north, The lot is in a rural area with dirt road and many vacant parcels. The listing agent entered the listing info into MLS, put a sign on the parcel, and even had a brochure box with a map on the sign.
Time passed and another agent eventually wrote and offer on the parcel and it was put into escrow. The escrow closed.
Six months later ... the Selling agent is calling the listing agent to report that there has been a huge mistake. The Buyer bought the wrong lot!
Apparently the buyer drove around the subdivision, looked at the available parcels, contacted their agent, made and offer, and bought a lot.
The selling agent never visited the parcel and never verified that the lot the buyer wanted was the lot she wrote an offer for!
Now ... wouldn't that just wreck your day?
