How much positive cash flow do you need a month?

[Andrew Holmes]

I have often wondered what is rich or well off? I am talking about purely passive income from rentals. 

Yes it is subjective and will depend on the individual but I was wondering what the BP community thinks. Would love to hear some input. 

In mind there are 3 stages

1. What you need to live on to meet a decent quality of life?

2. What do you want?

3. What are your dreams? The number for dreams can be way to crazy and high. So would love find out what some of the fellow BP contributors consider good. Is there an average?
