Wanted to share my experience with everyone on this thread after reaching out to Angie about her approach. I previously had posted my listings on Postlets and Craigslist for a month in a not-so-great neighborhood. I would have to sift through ~10 phone calls a day and another 5-7 "I am interested" responses on Zillow and Hotpads, etc. Most of them were a waste of time, in that they did not have the right income requirement, were trying to fit 7 people into a property of 1000 sq ft size, etc. It was completely exhausting. I reached a point where I offloaded the property to a realtor, who quickly got fed-up screening the property for me (she stopped responding to all notices and calls and just took applications from other realtors stopping by to show the property--lesson from that experience is to not sign a contract for longer than 3 weeks with realtors for renting out a property). In the meantime, I knew there was a better approach and with Angie's help, I was able to set-up a domain name/website for my listing, with a description and a re-direct to youcanbook.me to set-up appointments (this was especially useful for me as I am out of state, and wanted to limit my appointments to 2-3 general slots per week). Once set-up, I was able to secure tenants in a week and a half. This was also a lot cheaper than ShowMojo ($99 vs $12 Google Domain, $7 hosting, $10+4 YoucanBook.me).
Several more tips:
-Create 2 (or more) Craigslist listings and renew every other day to keep one of them fresh and near the top
-Prominently display URL at the beginning and end of listing description to re-direct applicants to site
-Do not share phone reference in your Craigslist listing--just place site URL to redirect them to book
-Use Rentlinx to post on ALL of the same sites that an MLS listing gets posted on (except listings on Trulia for some reason disappear in a few days)
-Use a same-area-code Google Voice number (if you're out of state), and adjust greeting to state that to schedule a showing must be done only via website and voice mails are only for previous applicants (you will need this as Rentlinx will share it with other sites unfortunately.. there is no workaround). Adjusting your greeting will convert the majority of your voice-mails into missed calls
-When setting up listings (through YouCanBook.me), mandate they state number of adults, income, etc (whatever you deem necessary to initially screen applicants). Also leave a comment/question box (will help you eliminate them when they ask if it's okay that they have a pitbull or mastiff, etc).
-You will need to pay youcanbook.me to schedule multiple appointments in one slot (I had group showings for a given 30 minute block). I also paid for SMS reminder messages for applicants.
-Come up with copy-paste email response redirecting applicants to your site if they express interest to you via the form on Zillow, HotPads, etc. Obviously do not share your Google Voice number in your email.
Ignore all missed calls / voice-mails (I had 74 total in the week and a half) and good luck!
