What should I do with a HELOC?

[Alexandria Nicole Salgado]

I found a lender who will give me a HELOC for my 2nd home with a variable interest rate of 8.25%. I can access about 150k at 95% LTV. I don't have a primary so this is the only option I've found after calling many banks.

Any ideas on what I can do with a HELOC of this amount with that high of a rate?
 
Currently, I only have one property which is an STR. My goal is to scale fast so I can quit my W-2.

Thanks!
