Hi there all, some great comments here, can I just add my thoughts. 

I believe that in any judgement on value for money of Cashflow Capital (or any buyers agent, or any other cost for that matter) is simply to add this cost to the financial analysis that would be (!!) used in determining the viability of an investment decision.  I don't recall seeing the fees charged by Cashflow Capital accounted for in their own feasability analysis numbers.  But, if the numbers stack up then I would go for it.
