As waterboy said there is a suit pending. A Lis Pendens can be filed against a property for many reasons, to long to go into here, but it does need to be resolved before title can be passed along. Why wouldn’t the builder renew? Again, lots of reasons, perhaps they want the Lis Pendens to get resolved, maybe they think they will sit out the fall and come back in the spring, maybe they want to do more work on it… Why would the second price be higher? Not sure… maybe they needed mo money out of it… maybe they had high demand….
I don’t have a clue about bonehead moves like that…but at least it is not in escrow!
