Talk:Constructing and upgrading costs and time/@comment-4855057-20130307140043/@comment-3991817-20130307142146

You are right that the 'normal' buildings (those that you can buy from the Build menu) are not always best to upgrade to lvl5 profit-wise. For the Hotel Lux it would take over 6 years in the best case scenario to earn back the expense of upgrading it from lvl4 to lvl5.

On the other hand, limited edition building have far lower upgrade costs and the costs for upgrading them to lvl5 can be earned back quite fast. For example, the Attraction "Sledgehammer", which was released last week and has one of the highest profits per tile in the game, only needs 141 collections (= 59 days) until it has earned back the costs for upgrading to lvl5.
