I wish this company had a different name... did you ever watch that episode ?  

If the cosigner is not contributing funds but is just helping secure the loan, whats a fair way to compensate them?

You’re definitely on the right track by planning to open separate bank accounts for each property and the holding company.

I will do my best to call 6 major insurance companies (not brokers) and get the scoop.

Understand what you are investing in....is it a secured loan, unsecured loan, membership interest in an entity that deploys capital like a feeder fund or direct membership interest in an entity that is the deed holder? 

Quote from @Moe Aly: Hey Everyone, just wanted to introduce myself, first time using bigger pockets, I am responsible for the wholesaling department in our company here in Columbus ohio and we assign around 15-20 deals a month!

Any recommendations of online companies with these services?

I’d love to hear from others who have successfully raised funds for similar ventures and any advice on structuring such a deal.

Was going for the best cost-of funds (lower rate)

Once you do, you'll have people who'll be able to refer you to the right companies.
