How to sell a block of residential/commercial/industry properties

[Ben S.]

I'm asking this question on behalf of my dad. Over the past decade he has bought up properties that make up about 2.5 acres in a single block. The surrounding area has low income residential, commercial, and light industry, and the properties he owns are zoned for all three. It has frontage on a fairly major roadway in town, and railroad on the back side. Right now there are several rental homes and a couple businesses run on these properties. This is in a mid size factory town in Ohio.

If he is interested in selling this as a block, how would he advertise it or who would he speak to, and how would he determine a reasonable sale price? I'm not really sure where to start with land value on a commercial/industrial property. He has spoken with some local brokers, but I'm not sure how much. Is that the main method of figuring this out? Or does that stay too local and it should be advertised more broadly?
