I've done one personally on a mix-used 3 unit and while it was an extensive process working with the contractors, submitting paperwork, and making sure that we were all on the same page, it was so worth the long, tedious process!

Purchase price: $65,000 Cash invested: $65,000 Purchased with a cash out refi on my original primary.

I actually just wrote the BiggerPockets book on Co-Living (25% off here https://CoLivingBook.com)!

I'm looking into getting a HELOC on our primary home in case I'll need to access some additional funds to finish. 840+ credit score. 

It covers key principles like saving aggressively, living below your means, and what your first investment should look like.Once you have a solid grasp on that, then I'd move into real estate investment education.

Be 1-1.33 DSCR, ideally 1.2 ish range with capex as a top line not bottom line item. 50% net cash flow= reserves, 50% net cash flow= investment #2.

My wife and I are currently house hacking on a street made up mostly of duplexes.

They are giving me great advice but I would like to find a way to incorporate them into the payment structure so I can get mentorship on tap.

You are still going to have holding costs and a heloc will just have less holding costs that you would if you were doing a personal line or hard money. 

When I see a house being worked on I sometimes stop and talk to the investor or contractor doing the work there.
