Heloc down payment vs capital gains tax

[Justin Bailey]

So 2 years ago I used a HELOC from my personal home to purchase the 20% down a rental property. I was looking into selling the rental property but would need to use the capital gains to payoff the 20% down. Does the heloc still account for the down payment? Or should I do a cashout refi to payoff the heloc and make my profit smaller?
