There are a lot of websites that monitor/ aggregate crime statistics. https://www.raidsonline.com/Websites like raidsonline aren't perfect indicators (for example, crime rates downtown appear high but the same market supports some of the most expensive apartments/ homes in Lexington), but they can be a useful starting point.

Bigger Pockets has some great state forums and usually there are good locals that monitor those.

I went the submeter route and am very happy with True Submeter, they send you the kit to have installed by plumber. https://truesubmeter.com/Then they monitor usage via the cell network and send you the bill (or your PM) to then bill the tenant.
