Creative financing advice??

[Robert Burciul]

A family friend has a friend looking to sell a three story 5 bed 3 bath home that could easily be turned into two or three units and is selling for a very reasonable price. The problem is I'm already balls deep in another deal and stretched end to end financially. But I want in on this investment. The current owner is open to having a buyer allow him to rent in exchange for labour on the property (I know it sounds sketchy but my personal relationship helps). I feel like there has to be a way I can get involved in this investment along with the other commitment in have already made even though i am already stretched very thin. The other property I plan to "BRRRR" but need to spent a bit of time and money on the rehab before I can generate any income and be able to move on to the next property. I'd hate to let this new opportunity go though as I see a lot of potential in the property and know I can get a solid deal.

Can I get in on this even though my plate is entirely full and my wallet is entirely empty? 

I would love any input!
