Commercial & Residential renting - Duplex

[Jack Glazer]

Under contract for a Duplex (1/1 back unit currently rented by a tenant, 3/1 front unit currently zoned for commercial use and fit for a small business) looking for any advice or tips about renting to a business.  The front unit is nicely suited for 4 offices, and has been used as such over the last number of years.  The seller's business has been operating there for a while and she is leaving, but I'd like to maintain the front unit for business use.  Any best practices for finding commercial tenants? Jacksonville location. 

Thanks!!
