We went through this on our previous house. It's not only the builder--but the county approval process and waiting for the "CO" or "Certificate of Occupancy". It was a maddening time, I remember that! The county wouldn't grant the C.O. because there wasn't a railing for the stairs. So we were delayed, and d e l a y e d, for a relatively simple problem. It would've taken the builder probably 1/2 a day to fix.
So there was the builder (not finishing up), and the county (taking its sweet time)...and all the while there were much more serious problems with the house than were ever flagged by the county inspectors.
Amazing how builders can suddenly lose interest when there's a buyer--even if there's money on the line.
Advice? Stay on the best possible terms with the builder. BUT!--Have an inspection done--builders can take shortcuts. Don't expect the local municipality inspectors to catch everything--in fact even glaring errors can slip by (bribes, perhaps?). Get the builder to finish as much as possible prior to closing date. Even holding a good sum in escrow wasn't enough to get ours to come finish.
Hopefully your builder will be different and everything will go smoothly. But I wouldn't count on it. And once you're moved in, enjoy your new home...and start settling in
Best of luck,
