What's the most important data investors need?

[Bradley Buxton]

I'm trying to put together a report for my clients that has only relevant concise data about our market.  I'm having trouble deciding what is the most important to include in a one page regular report for investors.  There is so much information available.  Thought I would as the BP community

What the most important data in a specific market for an investor to have on a regular basis when looking for investment properties?  What do you need to make a buying decision? 

Capital, Expenses, rates, etc... What else?
