What is refer-a-friend? Essentially, you make money for using a service and telling others how great it is. Most of the times, you’ll get a unique link that you can share with friends directly or throughout social media. Whenever anybody clicks your link and signs up and/or makes a purchase, you’ll get a bonus. The bonus can be in the form of cold hard cash or an account credit. 

One of the most important assets you have is your credit score. By taking care of it and pursuing the steps to improve your credit score, a world of opportunity can open up for you. If you need a loan to buy that rental property or some quick funding through a business credit card, a good credit score will help you get approved so you can build passive income.
I’ve built several businesses since 2008 using one or more of these models. I’ve been featured in magazines and articles across the globe, and since I started my journey I’ve generated over $5M in earnings from these businesses. All of my income and expenses for those businesses dating back to October 2008 have been tracked publicly on SPI.com. You can see 10 years of income reports here.

Real Estate Crowdsourcing – After selling my SF rental house in mid-2017 for 30X annual gross rent, I  reinvested $550,000 of the proceeds ($810,000 total) in real estate crowdfunding, based in San Francisco. My goal is to take advantage of cheaper heartland real estate with much higher net rental yields (8% – 12% vs. 2% – 3.5% in SF) and diversify away from expensive coastal city real estate which is now under pressure due to new tax policy which limits SALT deduction to $10,000 and new mortgage interest deduction on mortgages of $750,000 from $1,000,000 for 2018 and beyond.


Revenue sharing sites give you the opportunity to earn money online without having a website or a product to sell. If writing is your hobby, for example, then you can earn extra income by writing high quality articles and submit them to different locations on revenue sharing sites. I must admit I’ve never tried it, but I wanted to get it out as it can be a viable option to get started with.
It takes the “books I’m reading” area you often see in blogs (within Amazon affiliate links) to a whole new level. not only is this great for you, but it’s extremely helpful for your readers who may be looking for additional resources related to your niche. Plus, they may come across products or services they weren’t originally looking for while on your resources page.
Roofstock – Investing in rental properties is one of those passive income ideas that can be extremely intimidating, especially when it comes to finding tenants. Roofstock lets you buy properties with as little as 20% down that already have tenants living in them. That means you start getting paid from the first day of your investment. You don’t even have to physically visit the properties!
What I find most interesting is the fact that I had never considered options like LendingTree or realityshares for other income sources. Investing in property has been too much of bad luck for people that I know personally, so I am interesting in getting involved in a situation where I would have to be dealing with maintenance issues or tenants. There are services for you to do that, but I had not come across any that didn’t eat most if not all of the earnings. Then again, I live in the NY area. Investing in the midwest would not be reasonably possible for me, directly, but reading about realityshares is something I am going to look into further. That might be a real possibility.
Thanks for asking. https://passiveincomemd.com/what-is-passive-income/ gives a good summary of the definition I use. But in brief, it’s income that isn’t proportional to the time you physically put into acquiring it. It doesn’t mean it’s not without work or effort. It’s just that most of the work is done up front and it continues to pay off long after that initial effort. Real estate fits into that box. There’s definitely a spectrum but compared to what we do as doctors, where our compensation is directly linked to our time, most of these things are quite passive.
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.
The capitalization rate approach to real estate valuation is much more straight-forward but may not give you a true market value. The cap rate is simply the annual net operating income (NOI) of the property divided by the cost or value. Net operating income is the amount left from rents after all expenses are paid but before taxes and interest payments.

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.

When withdrawing money to live on, I don’t care how many stock shares I own or what the dividends are – I care about how much MONEY I’m able to safely withdraw from my total portfolio without running out before I die. A lot of academics have analyzed total market returns based on indices and done Monte Carlo simulations of portfolios with various asset allocations, and have come up with percentages that you can have reasonable statistical confidence of being safe.


Real Estate: I currently own one rental property in San Francisco which I bought in 2003 (2/2 condo), one vacation rental in Squaw Valley, Lake Tahoe (2/2 condo), and my primary residence. Real estate is my favorite asset class to build wealth because it is easy to understand, tangible, provides utility, and rides the way of inflation. I recommend individuals try and get neutral inflation by buying their primary residence as young as possible. The power of inflation is just too hard to counteract.
A quick look on Pinterest and you’ll see no shortage of awesome solopreneurs sharing amazing income reports. And many of these #girlbosses are all online courses creators! While these women (and men) are pros now, they weren’t always. Everybody starts at the beginning, so don’t feel like you need to be a well-seasoned pro to earn passive income as a course creator.
Ever find yourself humming a tune, or laying down tracks for yourself or friends? Your next catchy phrase might fetch you a solid passive income stream. On sites like ProductionTrax and Audio Network, musicians can license their compositions for background music in apps, commercials, and websites to earn more money. Read more about this strategy at The Guardian.
"What makes business work is creating value. If you're going into the business with the intention of not creating value, but of having it magically provide money for you, then you often make really bad choices. The business that you're investing in or creating doesn't tend to be creating value for its customers or for anyone. So it doesn't tend to spit off the cash you're hoping it will. So many times I've seen people pursue passive income, and end up having active losses instead. They just spend a lot of time and money trying to push responsibilities off on other people and having it not work."

Leverage: With the stock market, you invest your retirement savings or cash on hand. The same is true for private lending. You can leverage rental properties four-to-one, sometimes five-to-one, meaning your $50,000 investment can buy you $200,000-250,000 in real estate. In a rising market, this is a good thing and will maximize your cash on cash return.


While building apps for Apple (or Android) mobile devices can be a lucrative way to generate passive income online, it's not as easy as many people make it seem. Beside the fact that it’s hard to get your app noticed among the millions being released every year, most people expect apps to be either free or very inexpensive. In fact, a recent study found that only 11% of apps are paid for. The number of paid apps will only decline over time as more players join the market. The key, like many of the business model mentioned here, is to be strategic and creative from the very start. There are a few ways to monetize your app and keep it free for users. Examples include advertising, premium services, and sponsors. 

For someone my age, I have an extremely low risk portfolio of mutual funds, foreign currency, and bonds. It’s made a bit more risky by my recent exposure to cryptocurrency, but that’s the only “high risk” activity going on here. Nothing exciting, but it pays some nice dividends and beats the hell out of keeping money in a savings account. This is a way for me to hedge against the risk I incur by angel investing in startups.
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?
