Buy new home or get HELOC first?

[William Richard Arens]

I am ready to buy my second house hack! Before I get pre-approved, I want to know if I should take out a HELOC on my first home before or after?

Long story but I owe $460k on my current house hack which is appraised at $700k. I plan to get a HELOC first while im still an owner occupant, then applying for pre-approval to buy again.

Is this a good plan to get better rates? Or should I buy my new home first, then go back and get a HELOC?
