Tool to see at a quick glace if a property is a good deal?

[Alain Martinez]

Hello,

I'm reading Rental Property Investing by Brandon Turner right now and I'm at the chapter about analyzing a property and seeing if it's going to be a good deal or not.  There are quite a few things to take into consideration and instead of re-inventing the wheel I'm wondering if there is a tool (spreadsheet or otherwise) where one can plug in numbers and at a quick glance know if a property is worth a 2nd look?  I probably sound lazy but there's gotta be a tool out there.  Thanks in advance.
