My wife and I are on our first go at it right now. We used a HELOC on our current home to get started. We found a seller that wanted out fast but wanted cash. So we got it for 70k and it had just lowered to 80k that day. We were able to do “cash” because we had the HELOC. As of today, we’re past halfway on a reno that I budgeted 60k for and we’re currently pacing to finish under 40k. So now I just need the house to appraise for 165k and I’ll get my whole HELOC back. And the comps look great for us.
