My realtor (very good friend and successful) says take advantage of the market and sell it and find the next project.  

I guess I'll call a local realtor and pick their brain for some ideas, and at least get an estimate of what it could possibly sell for.

They plan on re-listing the properties with realtors though. 

You will need to hire a good local realtor that can give you accurate comps.

According to Zillow, it is under rent for $500 and for Realtor it is under rent for $200. 

Jessica Brown I’m surprised that no one here has mentioned to find a realtor and have them run a VAR or comps report.

Only thing beyond that would be the Realtor board fee and whatever I spend on marketing myself.

You need your funding lined up before you get properties under contract.As a Realtor representing a seller, part of my job is to be sure we don't accept an offer unless we're confident that it will close.As part of my due diligence, I contact the lender to find out whether the pre-approval or POF is solid. 

BTW- I have no beef with COMMERCIAL Realtors as they are a completely different breed or Realtor.

I had considered a realtors licence for more options and flexibility but i am not at all familiar with that process, any further advice on that front would be nice.
