Purpose of Collecting Houses and Hotels

Hi, I'm just curious as to the purpose of collecting houses and hotels. I've already completed the Collection, so I'm wondering if it's worthwhile to spend dice and "build" the hotel for a property as well.

Sorry if this question's been asked already. I had checked the forum, but hadn't turned up pertinent search results.

Also, I feel like this would be a good question to include in the FAQs. I can't imagine I'm the only person who has wondered about this before.

You get 1 Gem rewarded for each house or hotel :)

So after you complete the collection you don't get more dice when you bingo?

You will always get Dice for Bingo per Card regardless of if you finished your collection or finished reaching all of your houses and hotels.
