I'm getting many responses on a property in Denver but the format for the tenant responses on Zillow seems weak. Potential renters simply check a box that says "I'm interested in viewing your property and am available at the following times..."

Not my first circus here, and I want to speak with the real human behind the inquiry before taking the time to schedule and meet with a potential tenant and just see what shows up and if they show up. I"d like to ask what date they are seeking occupancy for, how many persons, vehicles, etc before spinning my own wheels. 

I then call their number listed by Zillow and leave a VM offering to answer questions on the property and ask them to give me a call back concerning the property and typically don't get a response. It seems people want to hide behind the keyboard anonymously without human contact in a business that is still person-to-person. 

I consider posting in the ad something to the effect of "stand out from the crowd and call the lowly landlord for further info or to schedule a viewing - landlord is only responding to phone calls. I do ask for interested tenants to give me a call, in the ad, currently. 

How can I do this better? I'd sure like to duck behind my keyboard each time there is a maintenance issue for example, but it doesn't work that way! Opening my doors to unknown people I've never even spoken to doesn't seem very wise.
