I have already come up with 50 ways that a management company can screw you for profit without you ever knowing(or not finding out for awhile). Did you have an inspection before you made an offer on the property? Do you have a picture of the property you bought? How do you know if that picture shows the house you actually own? or if it even hows the ‘current’ state of the house you own?

I prefer assets that make me a high return for the lowest amount of work possible (semi-passive involvement). And assets that pay me in several unique ways. Cash flow is only one way RE makes money for me. I also get principal reductions, appreciation, tax advantages (depreciation), and I control the rental increases on a yearly basis. Plus a majority of the capital is provided by the secondary market on 30 year fixed low interest rate debt.


Mechanical Turk: Amazon's Mechanical Turk is a resource for doing human-intelligence tasks, or as the site commonly refers to them, HITs. You get paid a very small fee for any given HIT and you'll need a good deal of volume to make a substantial amount of money. But it is a resource you can use in your spare time to generate a small income online. 
If you have a nice camera and a good eye, snapping a few photos might be just the thing you need to figure out how to make extra money. You can go as all-in with this as you want. Maybe you only shoot family sessions and birthday cake smashes on the weekends. Or maybe you decide to start a business as a wedding photographer! The choice really is up to you. 
Perhaps you're interested in measuring America. “Census Bureau Regional Offices conduct continuous surveys–other than the once-a-decade population count–to supply the nation with important statistics on people, places and our economy.” The US Census website states that the local field workers understand their communities best and are an important part of conducting surveys with residents. You get to work out of your home and you're also reimbursed for your mileage. The Census Bureau is hiring across the United States and you can search temporary field positions here.
A service like Paribus or Earny will help you collect refunds you're owed from stores. This is a great way to potentially put some extra earnings on autopilot because you're using an innovative tool to get a refund you deserve. When you make an on-line purchase at a Paribus monitored store (you can view the retailers they monitor here), Paribus engages with the retailer on your behalf and files a claim requesting a refund. When Paribus succeeds and a retailer issues a price adjustment, you are credited funds directly onto the original form of payment or provided the equivalent amount in store credit. It is sometimes necessary for you to call the company, or fill out a form to receive that credit in addition to Paribus reaching out. Paribus provides a convenient desktop version and an iOS app with a live feed of savings. Paribus compensates us when you sign up for Paribus using the links we provided.
We usually think of Craigslist as a place to buy and trade random stuff, but Craigslist can actually be a great opportunity to sell your services online to an active and engaged audience. Simply check the “jobs” section and “gigs” section for specific cities and see if anything matches your skills. The great thing about Craigslist is that it is one of the highest converting traffic sources on the internet (think active buyers) which can mean more opportunities at higher pay.
Let’s be honest. Those little people grow out of their clothes faster than you can keep up. When it’s time to get rid of the clothes they’ve outgrown, you have a few options. Put them out in your standard yard sale, sell them to a consignment store, or post them on social media. Apps like Kidizen are specially designed for selling your kid’s gently used threads. And of course, you can use other sites like Poshmark, thredUp, Craigslist and eBay to sell children’s clothing too.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.

Wow! What an awesome list! My favorite is the stock photography because I love photography. I have had some success there, particularly with one photo I make some decent income from. I think the key with stock photography is finding a shot that is high demand. Then, find a new unique way to frame that shot. This is the reason my St. Louis Arch photo is a top 10 on both ShutterStock and iStockPhoto. Thanks for the awesome ideas above!
This isn’t to scare you off. I simply want you to know that this guide is going to focus solely on ways to make real, sustainable extra income online. Not just a few bucks. I want to share all the mistakes I've made that got me to where I am now so that you don’t have to go through them, and can build a successful online source of income for yourself.

What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
