Stop in for a cup of coffee

Have a neutral third party there to record or witness all discussions. Best if you could get the inspector to be there as well. If you can't, an audio/video recording, letting them know upfront it's being recorded should be done at a minimum. And don't sign **** without a lawyer.
I already mentioned possibly having a coworker there. He used to work for a big name builder here and knows the ins and outs. He could run them up one side and down the other, problem is he has a tendency to piss people off. So Im not sure that would be good. I thought about recording it also. I have every single text message to them and my wife does also for all of her communications with them.. No way will I be showing them the only contract I have let alone sign anything else.. They will be getting bad google reviews and BBB reviews when this is all done.
