Find out what they do, how they do it, and maybe an idea may pop into your head about how you can apply their method to your own. 

I'm not sure what problem they think it solves to tax people for taking a risk to improve a property.

It's a way of saying "people in the market are willing to get 4% return on net income in an A area in this market, so if I know the net income of the 6 unit subject property, I can derive what someone would be willing to pay i.e. what it might be worth".Incidentally, when people talk about the "income approach" as one of the three appraisal methods (the others being sales comparables and replacement cost), it's usually introduced for exactly this scenario - that there are usually plenty of comps for 1-4 families and buyers are more likely to look at recent sales of similar properties to determine what they'll be willing to pay, but once you start looking at 5+ units there are both far fewer comps and the buyers are investors who really are looking at cash flow more than similar property sales.Anyway, I hope this helps.
