How to Analyze Package of Properties??

[Austin Hughes]

I recently got access to an off market package of 20 properties and am having trouble analyzing them. 

I could just plug the aggregate numbers into my analysis calculator and start there, but I don't want to overpay for houses just because they cash flow. IE: I could buy the package and get $10K Equity on one property and over-pay by $10K on another property.

Also, some might make better flips and others might make better buy and holds.

How have you guys analyzed them before? Advice is very welcome here.
