Analyzing cash flow/profit from a simplistic perspective

[Fred Shandler]

(Putting tax benefits, loan amoritazation and apperciation aside)

I continually think about what my goal is, in terms of how much money I want to make from owning rentals and how many properties I would need to support that. Let's say, my goal is to earn 50K per year off rentals. That would mean that, at $150 positive cash flow per property, I would need appx. 25 properties. Or, If I wanted to make 100K, I would need appx. 50 properties. I guess my question is -is owning 25 or even 50 properties an outrageous notion/goal for a individual investor, is it a realistic goal? Is this somewhat of an accurate basis for goals?

Thanks
