Where to put your money to grow?

[David James]

So I had an idea that of the money you get from a rental property (the expenses such as repairs, vacancy, taxes and CG) since you dont want to spend this and save for big ticket items in the future, where does people put that money? Would make a lot of sense to put it into something that you could gain compound interest and make that money grow even larger! Where do the savvy investors put that portion of the money?
