Finding Out My Equity Before a Commercial Appraisal

I have 2 scenarios coming up where I will need to do a commercial appraisal on some of my properties to utilize the equity that I've created. I need the appraisal to come in at a certain number or it won't be worth it for me to do it right now. I'm looking for suggestions on what to do prior to actually hiring an appraiser to figure out their worth? I'm fluent in residential real estate and doing ARV's, but I haven't gone through many commercial appraisals. Any thoughts? I'm thinking I would maybe just call a commercial agent and ask them for a market analysis?
