Numbers - Do they matter when the deal is overwhelmingly good?

[Paul Steward]

I had a deal that went south for one of my clients.  I personally thought the deal was a home run but my clients had another view.  Numbers not aligning was the deciding factor for them.  I'm not a pushy realtor and never will be.  The deal just seemed so great from my end and totally shocked me when they backed out.  

Can someone please explain why numbers are so important. 

Cashflow was great as the properties were.  Yes they needed repairs but they didn't need them right away.

How do you know a deal is overwhelmingly good without numbers?  Isn't it the numbers that determine if a deal is good or not?
