Suggesting to them buying their house for a wholesale range offer or lower dependent on the extent of the rehab, then having a contract in place that gives them a percentage of the profit to help get them back on their feet, paying off debts etc.

I'm more focused on residential properties, however, I offer a bit of everything.

Would be interested in connecting to learn more about your experience. 

I was thinking Form 8832 is the one, but I am confused when I get to question #3 since this entity is technically owned by more than one individual.

Need so much more info to actually be able to shop rates  :) 

But now I'm thinking of renting the whole house and getting a cheap apartment to save even more money.

This is more or less like BRRR where I can refinance after renting them out for as much as the cost to build.

Hope this helps, best of luck!

If you really don't want the stock account any more and are willing to take the tax hit, why not just sell it and leave the cash in your account?
