I wouldn't think of a high yield savings account as a source of passive income but your savings should be getting something (less like Seinfeld syndication residuals and more like a commercial jingle residuals!). It won't make you rich but it's nice if your baseline, risk-free rate of return on cash is 1% or more. The best high yield savings accounts (or money market accounts) offer higher interest rate and there is absolutely no risk. CIT Bank currently leads the pack with the highest interest rate.
I like the way you have listed the ways to earn extra income and was quite surprise that you did not make mention of network marketing, which is a way to make extra income without quitting your regular, though most people view mlm as a pyramid scheme but the real pyramid scheme is a regular 9 to 5, because you can only have one president of a company at any given time and network marketing business model to promote product that can be used is really cheap to join and can offer a substantial extra income or what do you think?

became $1,000,000 during an 18 year period (about 3x better than Berkshire Hathaway). Five – ten shares, or more, invested in a ROTH Ira and held *consistently* come h..l or highwater, with dividends and splits reinvested, may provide you a very pleasant surprise in 20 years or so. Asset Managers often do better than the assets they manage. Eaton Vance (EV) and T. Rowe Price (TROW) also did exceedingly well over a 25 year period.

Marketers aim to spread the word about their brand to a wide audience, and they often do this by trying to make their content go viral. Viral marketing is a technique, which marketers use intentionally to spread their message quickly. Just like a biological virus, a viral marketing campaign spreads from one person to another, resulting in a large number of views, substantial amount of social shares and remarkable brand awareness.
If you’d prefer to skip the startup phase, you might want to buy a blog that’s already built and earning revenue. This is actually pretty easy to do as a lot of people start blogs, and then get bored with them. Getting a blog going is a labor-intensive process, and it’s not uncommon for people to give up before they’ve reached their full potential.
Using influencers in viral marketing provides companies several benefits. It enables companies to spend little time and budget on their marketing communication and brand awareness promotion.[47] For example, Alberto Zanot, in the 2006 FIFA Football World Cup, shared Zinedine Zidane's headbutt against Italy and engaged more than 1.5 million viewers in less than the very first hour. Secondly, it enhances the credibility of messages.[48][49][50][51][52] These trust-based relationships grab the audience's attention, create customers' demand, increase sales and loyalty, or simply drive customers' attitude and behavior.[50][51] In the case of Coke, Millennials changed their mind about the product, from parents' drink to the beverage for teens.[53] It built up Millennials' social needs by 'sharing a Coke' with their friends. This created a deep connection with Gen Y, dramatically increased sales (+11% compared with last year) and market share (+1.6%).[53]
This can be a little easier said than done, but if you have a large social media following, you can definitely earn money promoting a product or advertising for a company. You can even combine this with different marketing campaigns if you are an influencer and have your own blog (advertisement + affiliate income). This is how many bloggers make money! Again, it is not 100% passive but once set up correctly and then scaled, can be surprisingly lucrative.

When money is lent to a partnership or S-corporation acting as a pass-through entity (essentially a business that is designed to reduce the effects of double taxation) by that entity’s owner, the interest income on that loan to the portfolio income can qualify as passive income. As the IRS language reads: "Certain self-charged interest income or deductions may be treated as passive activity gross income or passive activity deductions if the loan proceeds are used in a passive activity."

Unlike having to either create something or store a physical inventory of something, selling digital products requires no overhead and no active work to earn money. The blog Paper & Oats put together a great guide on how to get started selling on Etsy. In this guide, they share a few ideas on digital products you can put together and sell in your Etsy store. If you’re someone who’s creative and knows how to design great-looking digital files, this might be a perfect option for you.
I will share what we did, because it’s an incredible success story. We used an existing tax loophole where if you sell your primary residence (after having lived there at least two years) you get to keep your profit tax-free. So, we stair-stepped. We bought house after house, at least two years apart, used the profit money to pay down on the next house (so on and so forth, yadda yadda) building up equity as we went along… and now, we own a $600,000 house debt-free. And now we are using our paid-off home as leverage to borrow money to buy commercial buildings to rent out. I like commercial because it’s a BUSINESS transaction… kids, pets, other wear and tear that you see with residential rentals is nonexistent. People take care of their business space much better than residential. You have to be in a good area for renting out commercial – a thriving business community – to make this work. But that’s how we “made it”, and though it took 15 years, we will have residual income to take care of us when we’re old enough to retire. People made fun of us for moving so much, but who’s laughing now? 😉 Oh, and our child only had to change schools once (and we wanted to anyway) because we stayed in the same general area as we moved around. We were careful not to disrupt his life too much.

However, this comes back to the old discussion of pain versus pleasure. We will always do more to avoid pain than we will to gain pleasure. When our backs are against the wall, we act. When they're not, we relax. The truth is that the pain-versus-pleasure paradigm only operates in the short term. We'll only avoid pain in the here and now. Often not in the long term.
Ebooks are one of my favorite sources of passive income. Now, you can do this the simple way and just publish it on Amazon's KDP. Or, you can go all out and build yourself a book funnel. Book funnels are powerful, but they won't be fully passive. For example, if you do a free-plus-shipping offer for your ebook (converting it into a physical book), you'll need to create some one-time offers (i.e. extra training) and up-sells (i.e. an audiobook). But, a book funnel can be very powerful.

This is an ideal strategy if you live in an area where real estate prices are too high to realistically invest in, or you don’t want the hassle and expense of traveling all over the country visiting potential properties. Plus, if you are new to single-family real estate investing, letting a place like Roofstock guide you through the process is a great way to get your feet wet.
Among the many passive-income opportunities that exist, interest is a very popular one, along with dividends. Unfortunately, we've been living in an environment of ultra-low interest rates for many years now, so even a savings account with $100,000 in it might only grow by $1,000 or $2,000 per year. Interest rates seem to be rising, though, so take heart -- and know that in many past years, bank accounts and CDs and bonds have paid rates of 5%, 8%, and even 10% or more.
What I like about p2p investing on Lending Club is the website’s automated investing tool. You pick the criteria for loans in which you want to invest and the program does the rest. It will look for loans every day that meet those factors and automatically invest your money. It’s important because you’re collecting money on your loan investments every day so you want that money reinvested as soon as possible.

Conspicuous consumption is the practice of purchasing goods or services to publicly display wealth rather than to cover basic needs. Description: The word 'Conspicuous' here means lavish or wasteful spending. This kind of spending is generally made by people who have considerable amount of disposable income to spend on goods and services which are not necessary, but are more luxurious in nature.

To your point about Municipal Bonds, my concern is tax reform. While everything is mostly being worked behind closed doors (and likely wont ever see the light of day). There is still the chance they propose to limit the amount of the tax free nature of these bonds. While I dont sen panic in the streets, I do see a scenario where bond prices get additional pressure because municipalities have to increase rates due to people putting their money to work elsewhere.
Diversify safely but DIVERSITY. You do not need to get the best and highest return all the time. If so, you are not earning passive income you are earning active income which is taxed differently (see IRS.GOV passive -vs- active income definitions). As an investor you do not need to be chasing ‘the almighty dollar’. This is a losing proposition. Make the dollar come to you.

Viral advertising is personal and, while coming from an identified sponsor, it does not mean businesses pay for its distribution.[6] Most of the well-known viral ads circulating online are ads paid by a sponsor company, launched either on their own platform (company webpage or social media profile) or on social media websites such as YouTube.[7] Consumers receive the page link from a social media network or copy the entire ad from a website and pass it along through e-mail or posting it on a blog, webpage or social media profile. Viral marketing may take the form of video clips, interactive Flash games, advergames, ebooks, brandable software, images, text messages, email messages, or web pages. The most commonly utilized transmission vehicles for viral messages include: pass-along based, incentive based, trendy based, and undercover based. However, the creative nature of viral marketing enables an "endless amount of potential forms and vehicles the messages can utilize for transmission", including mobile devices.[8]
