HELOC Interest Only Fixed Rate

[Luisa Trigo]

Hello,
I am looking for a HELOC, 10 year draw period, interest only, at a fixed rate.
All I am finding is variable rate OR fixed rate for a HE Loan repayment principal plus interest.
Aiming to use the HELOC to cover the down payment on a four family so want to have the option of interest only payment and a fixed rate. Any insights appreciated.
Thank you!
