When starting a new search, the Location field always resets to California (no county). It would be nice if it remembered my last location (say “Nevada, Clark County”). A very small issue but sometimes I don’t notice the Location got reset and am confused by the results!
Oh, to answer my own question, I found this:
My Account -> Search Defaults -> State, County
Haha, now that is quick support!
Thanks Michael - we definitely aren’t as fast here on the forums as we are with software support using the support link above, but 2 minutes is pretty darn fast so I think you’d have had us beat regardless. 
PropertyRadar’s new app also allows you to set a default location. ?Simply click on Settings (gear icon, top right) then “Default Location” and set the county you’d like your searches to default to!
