Commercial Loan Question

[Kevin Boyd]

I posted this in another form. 

I purchased a 17 unit, 3 building retail/warehouse space for $2.15 mil. about 16 months ago. At the time it was about 65% occupied. It appraised for $2.3 million. I've done some remodeling, I have it fully rented, and have increased rents a bit. I purchased with an SBA loan with about $450k down.

I'd like to refi into a better rate and potentially capture some equity. This was my first commercial deal. The previous owner recommended I get a new loan through an insurance company. Anyone with a recommendation? TIA
