Where do you get information that determines market cap?

[Alex Tobias]

I mean where do you get information on an approximation of what market cap is to so you can start to see where a deal starts to make sense?

[Sam Grooms]

A deal starts to makes sense when it reaches your return objectives. You only need a cap rate to determine your exit, if it's required for your chosen return metric (ie. IRR).

All of the large advisors/brokerages publish cap rates on their websites for free.
