5. Rental properties
Purchasing properties to earn rental income is another way to build passive income. Long-term rentals can provide a reliable source of cash if they are located in a healthy market for renters, but they also carry long-term stressors like maintaining those properties, as well as paying multiple mortgages, property tax bills and other costs.
You could also focus on short-term rentals through a platform like Airbnb, which is dependent on a steady flow of visitors to your area. Or, start small: Rent out a room in your house to begin to bankroll your rental property empire.
6. Peer-to-peer lending
Real estate investments are long-term bets to build passive income. If you want to potentially earn income and cash out your investment in under five years, one tactic to consider is peer-to-peer lending.
An alternative to traditional bank loans, peer-to-peer lenders, like Prosper and Lending Club, match investors who are willing to lend money with borrowers who are vetted by the platforms for creditworthiness. It’s riskier than putting cash in a high-yield savings account or money market fund, but also potentially can earn more interest — as much as 5% or more.
7. Private equity
Perhaps the original form of peer-to-peer lending, another common form of passive income is funding a private business you believe has the opportunity to generate future income. For high-net-worth individuals, this might be investing in private equity funds, which are typically only available to accredited investors who meet certain net worth or income requirements.
Another way is to back a family member, friend or other trusted partner to help fund their business with an agreement to earn returns from any future profits. But beware: No matter how large or small, investing in a single business is an inherently risky, long-term bet. Never invest more than you can afford to lose.
