As a custom builder for decades, I dealt with this way more than once, especially with new subs that had not worked for me before.Back in the old days we used to just go with a verbal ok, but in the last 20 years or so, it is imperative to have a written CO (even an email sent from the jobsite) from the Sub and then I would add 20-25% and submit a CO of my own to the customer.

I would either use HML, Private Money, or partners if you are looking for help on financing these types of deals and building a business. 

I still get emails from turnkey companies and one of them (Martel Turnkey) said "stress free investing".

If you have any questions feel free to reach out or send me an email.

I'll shoot you an email.
