Days on Market research

[Paul Vail]

Forgive a simple question -- what tools are available to a non-agent (no direct access to MLS) to determine days on market for recent sales in my area? I'm presently using zillow (E.g., https://www.zillow.com/raleigh...).  

(I've tried boolean search tools here at BiggerPockets, but a support person here said 'Unfortunately, we do not have that search feature or functionality for forums and the marketplace.')
