Mafia wars secret

I started playing Mafia Wars by Zynga on Facebook and its a fun game, but there was a lot of unknowns when it came to buying properties. So I decided to create this helper worksheet so I could check which properties held the best dollar for dollar value when purchasing. Its easy to use and does all the equations for you!

Keep an eye on the light orange $/1K cells. The higher the value, the better the deal. As long as you update all the light green owned and property costs as you go, you will be able to buy with power. Also Im working on version 2 which will update your upkeep amount for you. Im hoping to find out if anyone knows how to feed the data right from the web app, to the worksheet, to cut down on you having to update the green fields, but right now Im not sure how to do it.
