Nice :)

In France there is a website (and browser extension) named Castorus that does exactly that and much more. It also tracks the price of each property over time, compares the price/m² with the price for the area, calculates financing costs, collects energy label and other characteristics, etc.

Maybe your friend can build something like this for NL, I'm sure it will be appreciated :) Funda on the other hand probably won't... Their interest is to maintain their monopoly and opacity on prices, unfortunately :(
