Are you committed to one contractor, or are there several that are bidding on the job?
Over the last two years I have been in talks with bout 6 contractors for this project. Most of them lead me on for many months then either ghosted me or told me they are no longer interested.
Only one of them gave me an estimate after nearly a year of asking them for pricing. He gave me a price in the 550k price range which is not compatible with my financials.
The only GC left is still working on getting me his numbers, I have been waiting for nearly 1.5 years for his estimate... I talk to him weekly, he still seems interested but I still don't have an estimate from him for the job. The job I tasked him with was taking the build far enough so that I can get a permit of occupancy, because I cannot afford a full turnkey build. I will have to do some of the finishing work myself.
On my own I started talking to sub-contractors because I can no longer tolerate the waiting.
I can get the dried-in barn shell put up for a price I can actually afford, then I'd be on my own, doing the work myself or subing it out to get the living space to code to the point I can move in.
I didn't want to go this route as it means the project will take a lot longer than I had hoped.
I wanted this place built and useable by the time I was 50. I bought the land when I was 29! I am now 51. If I have to build a lot of this myself I run the risk of being too old to actually use my shop for all the projects I have planned.
I screwed up by buying a house in 2009 instead of just building back then. COVID seems to have really messed up the construction industry for good it seems...
