how much cash flow is acceptable?

[Brian Campbell]

in using the property analysis tool, how much cash flow do you look for. Does 100 per month make you salivate? will $1 per month be acceptable. I am assuming you are figuring the more conservative of 50% of rent for expenses. Do you and should I even be using this as the major stat in deciding a good deal (obviously you want it positive). Is there another or better stat that is a better predictor of a good deal?

What is the first thing you look at after inputting data? The second thing? I'm trying to get an idea of what forms you deem most important and useful and how you use them.
