.), you can legally pay a referral fee on a commercial mortgage loan, as long as the referring source does nothing more than call you with a name and phone number of a prospective borrower.However, if the referral source — say, a commercial real estate broker — starts to negotiate terms (rate, points, term, etc.), then he is working as a commercial mortgage broker.

Most folks think that this is referring to a practice called basis shifting which would allow your moms estate to sell property to you at an inflated price in order to take advantage of the tax free step up in the estate.  

I think you are referring to companies that do equity sharing. 

You should have plenty of references to some there. 

@Vitali Ganon Recommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.
