I somewhat agree with Zeon, if you have the $15mil house and you have the $5mil to upgrade your housing, you would get just about the same gain in trains if you put that money into End. So if you have anything less than the Beachhouse, upgrade your housing first.

Another way to think of it is the gain you get from 100 points in happiness is equivalent to about 3700 creds worth of endurance, which is about $4mil depending on market prices.
