It's a thing of choice though as some people just prefer owning some properties just for owning sake. They don't mind if their property aren't productive, they just continue to acquire the wealth regardless. Some on the other hand, own properties for future sake, like for their children to acquire them when they become old enough. But to me, it would still be better to get properties that would earn us some reasonable amount of income continually for a long term. You don't actually have to limit your property, you can continue acquiring if you have enough money to buy more.
