Zillow: Visibility Algorithm or normal activity. Also, Bankruptcy

[Garen T.]

Hi all,

Is there anyone who understands the visibility that Zillow will show your property? I listed two rentals on zillow about 2 weeks ago. In the 1st day, I received about 50 queries on one of them, and 5 on the other. In the past 4 days, I've received 1 query. Is this a normal trend of lots of activity, or have I fallen into a space where Zillow wants me to upgrade (Pay) them to increase the applicants I get. 

In 2 weeks of having the listings up, I have received 2 potential candidates to see the units. Once I send them my rental criteria, I tend not to hear back from most of them. There have been these 2 that got a showing. One of them has been in her job for 10 days, and the other (a mom and her adult son) both have cleared up and resolved bankruptcies. One was chapter 7 and the other was chapter 13. They both maintained employment and rental with the same place throughout the process. They both have current credit scores above 650 (my min is 55) but I've not run them through a credit service yet. What is the best service to use these days to run a credit check? My intention is to use apartments.com to collect payments. I'm already there with a tenant and I like their system. 

Thoughts on both concerns? THANKS!!!
