Though it can take a while to build up enough cash to put a 20% down payment on an investment property (the typical lender minimum), they can snowball fairly quickly. The key here is to correctly project income and expenses in order to calculate cash flow (the free cash you can put in your pocket after all associated property expenses have been paid). However you have to be sure to include the cost of a property manager in your calculations unless you want to manage the property yourself. Even with a property manager, you may be required to make large repair decisions every now and then – so while this is not a 100% passive activity, you are not directly trading your time for money like traditional employment.

Passive income broadly refers to money you don't earn from actively engaging in a trade or business.

There are dozens of ways to generate passive income. However, the option you select has to do with two metrics: time and money. Either you have a lot of time or a lot of money. Most people usually don't have both. But, if you have a lot of money, generating passive income almost instantly is easy. You can buy up some real estate and begin enjoying rental income. Or, you can invest in a dividend fund or some other investment vehicle that will begin generating a steady income for you.
“There is no such thing as 100% passive income,” says Flynn. “Even with real estate you still have to manage your properties, or even with the stock market, which is potentially passive income, you still have to manage your portfolio. With online business, there is no such thing as 100% passive income — and this is coming from a guy with a blog called The definition of passive income is ‘building these businesses of automation,’ but in order to keep them automated and keep that trust going with your audience on top of that, you do have to keep it up every once in a while — so a lot of time upfront and a little time after. But there is alway time involved.”
