If you move title to the property into a trust for the seller's "Estate Planning purposes", you still need the mortgage company's approval. 

One way that I was able to get into my first property was counting 70% of the rental income of the other unit on a duplex.

Case Study: A Successful Joint Venture in Real Estate - An investor identifies a distressed property with high potential but lacks the funds to purchase and renovate it. - The investor partners with a private lender who provides the capital.

I think it's very dependent on the property and market. 

Are you moving to different neighborhoods, changing your renovation budgets, or holding properties longer?

Especially if the property is not yours.

Maybe an investor is flipping a lot of properties and you could offer to pick up and deliver materials to his crews, clean the work sites every night, bring his crew lunch, or whatever.Find a way to make yourself useful to them, and they will reciprocate.

I would suggest reaching out to owners of multi family who have no loan on the property.
