I'm currently in the very early stages of trying to roll an old 401k into an SDIRA and use the $22k worth of funds to get me involved in my first deal.

Part of these funds has already been ear marked for renovating our house to create an Airbnb unit, which will help the financial freedom goal, but that's not the focus of this question...

Used some of the HELOC funds to buy a SF that needed some work in which I moved into for a live & flip.

Let's say I contact multiple investor friends, and I inform them that I have the funds to potentially fund their projects.

Hey, I was toying with the idea of using a HELOC to fund a non-real estate investment, specifically buying some debt.

Ideally I know we use hard money lenders for funding and purchasing rehabs.

Where/how/ who can I get funding from?

In the past year, we started a renovation to add the second bathroom but ran out of funds (this is an attic conversion and our contractor was way low in his estimate).

@Gary Dawson, there is a way to do that with exchange funds but it is an additional process called a reverse or reverse improvement exchange. 

I am not an attorney and this is just from experience.IN philly I am coming up on my 200 th funding there.. and those row houses .. there simply is not much to them..
