How quickly can you collect income on 95% of your town?

Assume you haven't visited your town in over 24 hours. How long would it take you to scroll around and collect income from most buildings? For me it seems to be about two minutes but I wasn't trying for a speed run.

I say 95% because I know we sometimes have a building way in some corner that we may seldom feel like scrolling to and collecting from. Or maybe our scroll patterns happens to miss a little area and for whatever reasons we're fine with it.

Also, I suppose this question could be changed to also include clearing character tasks.
