I posted this about a year ago, but there's easy ways to get comparables for real estate and alot of times its free. Tom, from his blog http://dbreakfast.com//
mentioned that realtors are useful because of their comps on the MLS.
I never use realtors because its too much of a pain... The easiest way to get free comparables is to work through a title company. They provided me with a free account that basically uses http://dataquick.com
. To some, this is a little known secret.
So, now realtors are completing useless! ;-)
