If you are unable to search actual sales through the assessor, you can use properties currently listed for sale in the MLS. The problem here is that the asking price may not be a true reflection of what the property is really worth. You’ll want to be even more skeptical of high- and low-values in this list and I would discount all prices by at least 5% to find market value.
Though it requires a huge up-front investment (well, at least 20%), real estate is awesome, because it’s (usually) pretty stable, and it’s a triple-whammy: you make money by leveraging a bank’s money, you can rent it out with almost no work at all day-to-day, and the value of the underlying asset INCREASES. This is why so many people flock to AirBNB to rent out their apartments when they’re going on vacation, too. It’s pretty passive, you don’t have to own the asset, and you just hand over keys and hire a cleaner before/after. The value of your apartment is untouched. By contrast, imagine buying a plane and renting it out to people for tours — you pay tons of money to maintain it, and after 20 years, it’s value is almost nothing. The exception is if you can manage depreciation and somewhat automate the value-delivery. If you have an expensive tool (like a 3D printer) and charge people to come over to your house and print things on your 3D printer, it’s pretty passive for you to answer emails and open the door, so I give it a “Semi to yes” for passivity.
Consider refinancing your mortgage if you haven’t done so in a while before interest rates go up further. Or consider leveraging cheap money responsibly to acquire hard assets. LendingTree Mortgage has one of the largest lending networks online, and they will contact you immediately with their offers. You want lenders competing for your business, and get hard quotes so you can pit them against each other.
(Of course, you can also always get passive income by buying-and-holding US Treasuries, which are paying out around 4.2%. The BLS just reported inflation at 3.6%. No one's going to get rich with that level of passive income net of inflation. And according to Shadow Government Statistics, the real rate of inflation you and I are actually experiencing---including at the grocery store checkout line, at the gas pump, and at the doctor's office---not the massaged statistics the government puts out, is actually much higher, perhaps up to 11%. So government bonds could actually be not passive income---however meager---but passive losses.)
In 2012, even I wrote a 150-page eBook about severance package negotiations that still regularly sells about ~35 copies a month at $85 each (2nd edition for 2017) without any effort. In order to generate $2,975 a month or $35,700 a year in passive income as I do now, I would need to invest $892,500 in something that generates a 4% yield! To earn $10,000 a year in passive income would therefore need roughly $250,000 in capital.
All ideas take some amount of time and money to come to fruition. Some people have a lot of one of these, but not much of the other. A lot of successful ideas have started when one person had the resources that another did not. And many businesses have been started using 0% loans from credit cards to fund their concept and keep the business going until it achieved success.
One of the easiest ways to increase your passive income is to shift your savings to a bank that pays a higher yield on your savings — for example, Discover Bank and EverBank pay almost 1% for your money. Although it doesn’t sound like much (especially in this low interest environment), little things do add up and eventually interest rates will rise.
This encompasses everything from eBooks to stock images and even Udemy courses. The idea here is to create a digital good that has value. Why digital? Well, if you’re creating really unique hand-made socks, you can’t just duplicate them and resell them. Furthermore, you have to pack and ship each pair. Both of these things mean that there’s a fixed ratio of labor to income, and we’ve already discussed why that’s not ideal. Digital goods can be duplicated, and we can engineer systems (or use online marketplaces) to deliver them automatically. Awesome.
If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
