Advice needed. Selling a commercial property in Columbus Ohio and no idea what to do...
I need some advice. I have a property I am listing  in a couple weeks and have no idea what to expect in this market. 

I have a 3 unit and a single family in downtown Columbus that are on High St near The Ohio State University. The properties are connected with a parking lot and I own from the alley to High St. The University rezoned me to 6 stories so it’s an amazing opportunity for a developer. 

Comps are not looking good as we only have about 50 multi families listed in Columbus. 

What do I do to get the most value from this property?  

I have had Realtors tell me 1.5 to 3m but nothing really matters unless the buyer shows up. 

Help!

Depending on how this goes it might be interesting to reach out to a few of the limited partners (equity contributors) that have been invested in  local projects. The names are sometimes visible on the developers website or through a google search.
