I use the Credit Karma app on my phone (free).  

It shows a schedule of rates and there is a phone number you can contact them.  

Car magnets are not going to get the phone ringing off the hook.

(Nothing takes 15 minutes) Various back end phone calls with the listing agent to get the back story, calls to zoning, building department and a contractor or 2 to get briefed on issues discovered at the showing.

Does anyone know of any county assessors that provide you with the owners phone number?

The 19 y.o. kid that picks up the phone when you call the utilities company won't.

Then lookup thatsthem.com to find phone #'s to call and also find some email addresses if available.

Very few return a call, several have full mail boxes on their phones they clearly dont empty.

Also once you get a homeowner on the phone, what should be your thought process?
