However, sounds like there are probably some legal exceptions, so like you said in your post, you should consult an attorney.

It appears you need to do a workout with a servicer or consult an attorney.

@Anthony KondorWhile I agree with the feedback given by @Todd Dexheimer,  at the end of the day you should consult with a securities attorney and have them draft a contract for you.

It would also be wise to consult an attorney to help set up a structured protection, LLC or Corporation in order to protect your assets.

You can also meet arch, eng, and other consultants through this organization.Good Luck,

Personally I work as a consultant in a forensic engineering firm that investigates improper construction in Florida but we're way to pricey for a job this size. 

Rather than paying cash, I pay for some services via Venmo, PayPal, Zelle, etc. for record keeping purposes, but I am not sure if paying your children would be considered deductible or not so that part you should consult with a CPA on.

I currently have a Scorp for my consulting, but I should use LLC for investing?

Based on our research and consulting with our RE attorney, I will attempt to sum it up. 

A side note is that my day job as an engineering consultant for arbitration/litigation disputes puts my legal risk tolerance higher than most, but I'm trying to avoid litigation unless it makes sense.
