HELOC or Cashout Refi?

[Shannon Vistisen]

I'm looking to purchase my first property this year. I was leaning towards a cashout refi due to the locked in interest rate. But am now wondering if a HELOC would be the better option. How much ch does the interest rate move when working with helocs? And would the smarter route be a cash out knowing that interest rates are going to go up in the near forture.

property: will be a SFH as a short term rental.
