Refinancing Into Interest Only Fixed Rate Debt - Options?

[Richard Phillip Lewis]

Im in the process of finishing up a 203k House Hack Duplex. I got a good rate of 6.25% on my mortgage given today interest rate environment. I will be living in one side and renting the other side. I would like to refinance out of the FHA 203k 6.25% into a Fixed Rate Interest only mortgage till interest rates come down near or below 5%. Ive been search online for Interest only "Landlord" mortgages, but Im not seeing any available interest only products out there. Ive ready about 10 year Interest only / 20 year Fixed Amortized products, but Im not seeing any products ready to apply for. Where should I be looking?
