I gave up then, but your post makes me think I may want to try again.Who do you get your data from?

An agent can be a big help since they can provide you data is difficult to get from any other source.

Two things that helped us move past that point was the local REI group and as a result of that group a product that was introduced that allows us to run comps based on MLS data. 

Next time, I will do this prior to the purchase to get more data.

You can search the forums of this site to find out more information on list source and others (Melissa data etc.)

I am a Realtor, so I have access to the MLS to get the latest data.

They have regular meetings, tons of data and members share resources and help each other regularly.

Not to mention, it will give you a core foundation in markets you are interested in and, in doing so, help you formulate the exact specifications of data/info you need a private firm to provide you with should you ever invest capital into one.Sorry Jack, I've got nothing when it comes to books on this subject.

Are any investors purchasing Data Breach or Cyber Liability Coverage? 

Anyway, I have other suspicions about the quality of their data management and lead tracking because I used to be in the online lead generation business but I won't get into the weeds on that.My guess is that they are charging in Colorado because they've determined that they have enough eyeballs and marketshare where they won't turn people off by adding the fees.
