The best thing to do is network and get cool with a few realtors, who can provide you with the data you need.

Cool!

Also the builders will usually offer some cool incentives to the buyers with rate buy-downs and free extras.

I dont know if Chicago has it yet but most mls or mlx systems are switching to a login system that you need a code from a little device that cycles every 30 seconds so even if you get the login and password from an agent you will still need to be on the phone with them every time you use it.

Cool

Update: Over the last few days I have been using Google Finance quite often and I have to say that some of its features are very cool.

Your numbers seem cool... alittle high, though.- You do not want the rent credits + the down payment to exceed your spread.

Cool thanks for the clarity...

I am a fan of Digg and Slashdot, and it is very cool to get to the front page of either.

However usually it is more like a Cool Online CV explaining who you are and of course links to your websites.
