Building a map of comps in your area

[Sawyer Smith]

In the last year, we have had 20 of our properties appraised and refinanced. Our comps are close but there is room for improvement. I would like to create a database of all our previous appraisals and the comps used for those appraisals in order to be more accurate in analyzing future deals. That way we are not guessing on what the comps will be in certain areas.  Does anyone know of any programs that can display this information on a map or maybe have any other ideas on how to organize it all?

@Bryan Noth We have one of those. I was mainly thinking of something where you could pin all those addressed on a map just as a visual reference of what homes are priced at in those certain areas. Where I am investing the value fluctuates street by street almost. If we were able to have it on a map I thought it would make it easier for us to see trends in what areas we wanted to be in or stay out of.
