Can I use a heloc to do a house flip? How do I do it?

[Michael Lozana]

I currently own a duplex and have one side rented on airbnb. I'm living on one side and renting the other on Airbnb.

Mortgage is $2k per month and airbnb is generating $3500 gross per month.

the bank just approved a heloc for 250k. Is there any way I can invest that in something?

can I buy a house with it and flip it? if I can I'd like to remodel most of it myself.

or are there better ways I can invest it?
