How to valuing the property for appreciation?

[Vivek Sapre]

Hi,

I want to get an idea from all those people who invest for appreciation on how do you guys calculate the worth of an investment.

What about current negative cashflows howmuch do you consider worth. Can you give some insight into this. 

do you have any worksheet to look at the calculations 

Till now I am only doing cash flow based investments so this will be helpful.

Thanks
