Strategy to secure commercial tenant

[Clyde Myers Jr]

Hey All, new here (internet forums period actually).  I own a commercial office/warehouse building and recently lost my tenant to them purchasing their own location.  Problem is, my broker (also my best friend), specializes in residential and has simply thrown the suite up on loopnet ONLY fielding phones calls with his fingers crossed.  Oh and he also has a 4'x8' out in front "For Lease".  

Specifics: The space is a 11,500 sq ft comprised one fourth office and the remainder warehouse. I pay everything so no NNN. Demographics: 3 big neighborhoods surround with 20k+ vehicles passing by on 4-lane daily. 1151 N Loop 336 E Conroe, Tx 77304
