I think my head is going to explode

I just found out that our new house will be ready a few weeks earlier than expected. We can probably get the keys on Sept 20th or very close to it. The possibility of the house being ready AHEAD of schedule never really crossed my mind (you always hear about the opposite). My co-worker's daughter moved to Vegas a month ago and her house was massively behind schedule. Many people told me about delays due to supply shortages in the area. This was the last thing I expected.
I'm excited but my stress level just got cranked up to 11. Most of our ducks are in a row but this gives us less time to assure my transfer, less time for Niki to find a job, more time making huge mortgage payments while we wait for our current house to sell (doable but far from ideal), etc.
At least we don't have to wait as long for the house warming party catered by fat Tuesday. Woohoo!
