Thanks for the replies so far.
1. For liability I'm thinking if someone gets hurt on the job site, we find out the home building materials were toxic, something along those lines. As far as financial liability for the loan I'm good with that. Perhaps these liability issues aren't something most people building think about and if so I'd be interested in hearing that. I am pretty averse to that type of liability due to having significant assets and a strong W2.
2. Cash for liquidity is no problem. I've got that covered.
3. Experience - We've been building for 10+ years in this market and have successfully built and sold 200+ SFHs
4. Banks - I have some that I've spoken with informally and they are interested. I will ask them specifically how they would like it structured but I'm sure they'll ask for what is best for them. I'd like to present an idea that is palatable to them but best for me and my builder.
Basically I'm wondering if we should start our own LLC (owning it ourselves, "hiring" out the construction to his other LLC to avoid layering), or can I have his company get the loan and I just sign something showing that I'm providing the cash, am on the hook for the loan, etc? It seems like that paperwork could get complicated. Any other ideas for the best corporate structure for this planned endeavor? Again, thanks to everyone who helps!
