This time last year I was watching the inventory very closely as we seriously considered moving back to CA from NY (changed our minds – new, better job here for my husband, and thanks to global warming, upstate NY is not so bad last year or this! : )
Anyway, I was keeping track and there was a marked uptick in inventory in those areas even a few days after the New Year. It continued increasing steadily until late February / early March when suddenly it exploded. I think if you are patient, you will see the same, and the builders will change their incentives and pricing yet again.
