Investing Rental Income

[Mohamed Farih]

Hello everyone I had a question about investing rental income.  I am not asking for advice on what particular investment I should invest but I was curious to hear what everyone else might be doing with their additional money to help it grow.  

I was thinking to help my rental income grow.  I should invest it into the stock market or some other investment (of course I leave emergency funds in case something happens).  What do you guys do to help your money grow faster instead of having it sit in your bank account.  Look forward to hearing from you guys.
