At this moment how I do it: The initial score is 0, based on year of construction (newer is better ofc) I add 0-36 points, amount of square meters I multiply by 0.5 and add it as extra points, based on how prestigious is the district I add extra 0-4 points and there are many other things.

So why it's not possible like that to give score to each apartment? I mean if I find right weight for each parameter? How f.e. google rates websites, I guess it gives some kind of score to each of them? Or not?
