Is there a map program that lets me mark properties and give details?

[Brant Richardson]

I am wondering if there is a program that would give me a blank map of a given area and allow me to mark addresses and leave notes about the property. Something like the Zillow map with property borders but only has my marks would be ideal.

I am currently trying to learn a new market. It would be helpful if I could take rental information from Craigslist and put it on a map. I would like to mark each address that I known the rent on, if clicked on it would give the details like beds/baths, year built, and my rating of its condition based on any pictures I found. I could then use a different icon for properties I am interested in buying to do comps on what to expect for rent. Maybe have a third icon for properties owned, hopefully lots of those. Might be helpful for knowing when to raise the rent too.

Is anything like this available? As I was typing out this question, Google Earth came to mind, I'll have to see what I can do with that.
