Use HELOC to BRRRR questions

[C-Dell J.]

Hello good people! I've read and researched a lot on using BRRRR strategy. But 1 part I seem to not hear or miss is, I understand how to use refi/cash out to buy the next property but what happens to the current property after cashing out/refi?🤔

1. How do I pay off rentals faster than 30 years if I’m taking out (cash out refi) all the equity? I assumed people generally rely on aggressive rental cash flow.

2. How to or can I refi HELOC (in order to pay it off) if it's not 25% or enough equity?
