Mdhc advice - refi/rent out and new mortgage advice

Hi! I bought a primary residence 180kish with MHDC loan to get a 5% rate October 2024. I need to move for my sons school and I want to buy a new primary and keep the MHDC house as a rental. I cant insure the MHDC cuz my mortgage owner Bank of America has it flagged for primary due to grant status. I’m wondering what’s the best way to refi or convert this property and is this even possible - can I just pay back the grant to Missouri convert to traditional primary mortgage live here and then I can convert it to a rental and keep my interest rate low? 
I have one rental cash flow is $150 since it’s 300k mortgage with high rent in the area $2400/mo and I need new tenants by August. It has low interest rate and 5% down since it was a primary initially. 

Thanks for any advice
