Speaking from our own experience, you can’t be a passive McDonald’s franchisee. Every McDonald’s potential franchisee will need to complete at least thousands of hours of training before he/she would be approved to acquire a franchise and only if he/she has the financial resources to acquire a franchise. It could take years before one would get a single store franchise. Until the franchisee eventually has acquired multiple stores and established his/her own management team, the franchisee would have to put his/her nose to the grindstone and work his/her ass off every day. I won’t call it a passive investment by any stretch of imagination.
We have decided to invest in 2 ETFs, a multi asset allocation ETF (Fixed Inc, alts and div paying equities) and a preferred stock ETF. This will cover almost 45 percent of our deficit. We will be extremely diversified, can access the markets at a very low cost and the investments are liquid. On this pool of $, we have no plans to invade principal unless the investment grows by 20 percent, which we think is unlikely given the characteristics of the investments.
If an investor puts $500,000 into a candy store with the agreement that the owners would pay the investor a percentage of earnings, that would be considered passive income as long as the investor does not participate in the operation of the business in any meaningful way other than placing the investment. The IRS states, however, that if the investor did help manage the company with the owners, the investor's income could be seen as active since the investor provided "material participation." 
Passive income bluntly is income that would continue to generate if you died. Morbid. How about this? Passive income is income that would continue to generate if you decided to do nothing and sunbathe on some beach. That sounds better. Passive income includes rental income, royalties and income from businesses or investment partnerships / multi-member LLCs where you do not materially participate.
This is certainly not in my wheelhouse, but time and again people have been able to make a lot of money from creating and selling an app.  You can offer the app for free to users, and if enough people use it you can then charge for businesses to advertise (just like #5) with you.  You can also offer a version of the app that has no advertisements, but the user must pay a nominal fee to have this version.  Either way once you have created the app and it is in the marketplace, it has a ton of potential to generate passive income.  Depending on the app, you could also be bought out by a larger company and given a lump sum to walk away.  This happened to Garret & Jessica Gee.  Garret developed an app that was eventually sold to Snapchat for $54 Million!
We have 1 rental at the moment and we are renovating the second one. Last year we generated over $14,000 net passive income (after mortgage payments and taxes) from one apartment, and all I had to do was go in to inspect the property 3 times to make sure the tenants weren’t destroying it! It turned out they kept it in perfect condition and they were lovely people! Call me lucky.

I hope you remember me for my good qualities and not my bad ones because I have plenty of both. As far as the tax bill, I’ll have a podcast coming up on it but probably won’t do a post until it’s law and probably not until well into the new year. I’m sure I’ll offend all of my listeners with the podcast and the post, both those who think the tax system should be more progressive and those who think it should be less progressive.
You may already know there is a difference and you may know generally what that difference is, but it’s likely you don’t truly grasp the implications of those differences. For the record, there is nothing wrong with either of them. But if you want to maximize your returns down the road, you do want to make sure you really do have a solid feel for how these two differ.
Use your base to build your audience, and when you’re starting out, take advantage of the fact that you don’t have a big following to give more personalized help to your first fans. “The people who are starting out — that’s their advantage,” says Flynn. “They have the opportunity to speak directly with those people few coming their way to find out what their problems are and give them the special treatment that bigger brands might not be able to do.”
If you sell your entire interest in a passive activity through an installment sale to figure the loss for the current year that isn’t limited by the passive activity rules, multiply your overall loss (not including losses allowed in prior years) by a fraction. The numerator of the fraction is the gain recognized in the current year, and the denominator is the total gain from the sale minus all gains recognized in prior years.

An item of deduction from a passive activity that’s disallowed for a tax year under the basis or at-risk limitations isn’t a passive activity deduction for the tax year. The following sections provide rules for figuring the extent to which items of deduction from a passive activity are disallowed for a tax year under the basis or at-risk limitations.

A former passive activity is an activity that was a passive activity in any earlier tax year, but isn’t a passive activity in the current tax year. You can deduct a prior year's unallowed loss from the activity up to the amount of your current year net income from the activity. Treat any remaining prior year unallowed loss like you treat any other passive loss.

Another common way to earn passive income is to invest in real estate. This does involve some hefty investment on your part to get started, though, since real estate doesn’t come cheap. The goal is to earn enough back by renting out the property to not only cover your original investment, but to also turn a profit. Keep in mind that similar to letting your room through Airbnb, this venture may require some time and money to maintain. Plus, you will have to rely on others and tenants to keep the property in good shape.

Those who don't meet this test can qualify for a limited $25,000 allowance for losses if they qualify as an active participant. Active participation requires only limited activities, such as approving new tenants, setting rental terms, and approving payouts. If you qualify, you can then take up to that limited amount of loss each year, carrying over any excess losses until you generate rental income to offset it.
I do agree that a few of these ideas are not bad, but for me the problem with some of these platforms has been that I’m not from the USA. So, I can’t operate there. It’s a really interesting possibility to get some extra bucks from doing what you would do either way, like shopping. One of the best projects so far that I have seen is FluzFluz. It’s simple and really easy to use for everyone who uses Uber, Amazo, or other apps. The best part of all is that you can get some passive income – not just from your own purchases, but from other people’s as well. I hope one day it will make it here to your list. I think it’s worth it to check out.
