Add additional claims based in equity.

I have an opportunity to pull up to $150,000 on a HELOC on my home.  I am considering doing 2 things. 
1.) buy a duplex/triplex/quad
2.) buy multiple single family homes
I want to be able to make the most bang for ...

We have a duplex that We refinanced(02/2021) with our current mortgage company We were unable to pull equity out even though we have about $600K in equity in the rental. 

My initial thought is the best case scenario would be to cash out refinance my current home (i'm estimating $30,000 in equity) and buy another house to do a live in flip so I can rent my current house and use the cash to put towards another house.

Off market, well-maintained, value add, built in equity - everything that we love!

I have an estimated $100k in equity that I could pull out with a cash out refi if I wanted to refinance again and increase my savings to around $150k. 

A few of them have at least 100k in equity. 

I was wondering if any investor have experienced partnering up with a wholesaler but instead of paying the wholesaler an assignment/finder's fee, the wholesaler got a share in equity and got paid after the house is fixed up and sold.

(we inherited this business) its about 1 mil in equity. what would you do? 

The value has grown to $200,000 so I have about 93K in equity right now.I want to use some of the equity towards a down payment for a second rental in the same area.
