HouseHack still generates wealth even if you are not cashflowing.

I'm focusing on starting my portfolio with 2-4 unit multifamily buy and hold rentals in the local market where I live with the goal of generating substantial cash flow independent of my W2 job.

How do you guys usually find leads? Anyone care to explain on that topic?

The way to get to $0 tax as an agent is to own rentals that generate losses on paper.

For example, if you ignore appreciation but find a 2% deal in a rural area, you will win that metric, but if the house costs $60k, then you are only generating $1200 gross revenue and after all expenses, the amount left over is not great, and your appreciation potential is next to nothing. 

@Anthony Therrien-Bernard  we bought one of these purely for rental income to capitalize on the Outdoorsy bandwagon: https://droplet-trailer.com/  Not exactly a car, but similar in that it's a low cost depreciating asset that generates a good return. 

As far as tapping into your equity, HELOC is a very popular option, just make sure you work with a lender that hasn't historically been known for randomly reducing or closing the line of credit.

I would suggest spending some time determining what strategy you will employ to generate the return you are looking for. 

How much revenue does this generate?

They generate a positive cash flow, but only because there's no mortgages.
