Passive income is a must in today's community. Be it investing in dividend paying shares, renting of real estate, and more, you want to be up to your neck and beyond in passive income. If you can make a living, or a decent share of it, you can devote more time to what you like instead of work.
I invested in a quadplex straight away when I started fending for myself. Sure, I took a loan, but it was paid off easily through renting out the other three units.
