HELOC & then Cash Out Refi???

[Rommel R.]

I've been saving cash to start my BRRRR project my Family wants a pool built. Our primary home had accumulated at least $50k of equity in 9 month (From $248k to $307k). My question is, if I tap into my equity through HELOC to build a pool in our backyard ($60k to build), then appraise the house after pool build (approx $400k comps), how soon can I Refinance our house? I want to cash out some equity to begin my first project after the pool project. Any constructive input is appreciated.
