Refinancing mortgage that is now an investment property

[Naomasa Hase]

I was wondering if anyone has any experience or knowledge about refinancing a mortgage that was initially a primary residence that has now turned into a rental property.

In 2015, I purchased a condo on a physician loan 7/1 ARM, 0% down at interest rate of 3.5%. I lived there for 3 years and moved out of state. I kept the property and have been using it as a rental property. With the fixed rate time window closing in 2 years, I wanted to explore refinancing. My question is if banks will continue to finance it as a primary residence as it was when the mortgage was initially taken out or they will now look at this as an investment property and adjust rates accordingly.

Thank you for your help.
