Currently, I've been outsourcing this task, but due to some recent success with helping people close on houses, I want to reinvest my earnings in a company or individual who can handle this for me.Specifically, I'm looking for a small business that could benefit from some financial backing to expand their operations.

Our Idaho properties continue to treat us well, paying us in both equity and cash flow!

Or could another broker at my company list and get paid commission so long as the company doesn't retain any profits and just acts as a pass-through entity to pay the other broker? 

The only benefit in this instance, as an investment partner in a JV, or member in a multi-member LLC, is it's an act of "good faith" on my part in the agreement, being extremely transparent about the project's costs for the construction company, and the specific amount the partner/member invoices as profit or salary attributed to construction services on the specific project (I differentiate profit from salary, as it depends on the size of your construction company, a smaller company the profit may be the salary etc). 

Several of the companies you listed, ex: propstream are great list aggregators, but their add on services (such as skip tracing) can be sub par. 

If you are looking for recommendations on who the best turnkey companies are to partner up with, then I am your gal.

Ideally, it would be great to deal with a company that has a call center where I could pass on these leads.

I plan on using a property management company in order to keep the property in order until I move (eventually I want to bring property managers under my own business entity to focus only on my properties). 

You can continue to roll over for up to 5 years.If you cannot use the charitable deduction, you can sometimes sell the properties to a high income individual who CAN use them. 

It's been pretty hard finding companies that do this so I would like to ask all of you.
