After you’ve built up a solid credit history by paying your mortgage for the duplex on time using your work income and rental income from the tenants, you will eventually be able to scope out another property. Get a mortgage on that, move in and rent out the other half of your duplex. Over time you can continue building up your holdings, but it will take years and years of grinding to start to make good income.
3. Next option: Open your telephone book, turn to the Business Yellow Pages, to 'C' and find all the local Churches in your community. Get the phone numbers of the Church's office, and start calling them. You will want to inquire at the Church's office, whether they have a Benevolent Fund. You may find it convenient to have a pen and paper handy so you can keep track of who you call, and which ones give money away. Ask to make an appointment to apply for any that say yes.
Another option that isn’t quite cash back but is along the same lines of “make money by saving money” — the Honey Chrome extension.

That means no more wasted time Googling “[insert store name] coupon code” just to come up empty-handed. Honey does all the legwork for you!
If you live near a university, there are likely all sorts of research studies looking for participants. While I was an undergrad at Virginia Tech, I got paid $500 to participate in a 6-week dietary study. The study provided all my meals and paid me, but I had to eat a 5,000 calorie diet of 50% fat for 6 weeks, plus I had multiple muscle biopsies, urine/blood testing, etc.
If you’ve received gifts you really don’t want – and they’re still in the packages – try returning them. Some retailers will take them back up to a year later. If you are not sure where the item was purchased, try going online and searching. If a retailer like Walmart or Target pops up then you can return it there without a receipt and get a gift card.
Drive for Uber or Lyft: If you're in a locale where you can find Uber or Lyft (or even one of the many competitors around the world such as China's Didi), you could easily make a respectable income. The hours are flexible and you can work as you see fit, making it perfect even if you currently have full-time employment but are looking to make some money on the side.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
