With a net worth of $153 billion, Amazon.com Inc. Founder Jeff Bezos can probably afford to buy any house he wants. But right now, he's renting.

Bezos and his fiancée Lauren Sanchez are reportedly renting a home in Malibu, California, from legendary jazz saxophonist Kenny G for $600,000 per month.

The 5,500-square-foot house comes with a huge backyard, pool, screening room and recording studio. It also has a 3,500-square-foot guesthouse.

The estate gives the couple access to Little Dume Beach, one of the most exclusive beaches in Malibu.

With the rent being over half a million dollars per month, you might expect the property to come fully furnished. But that's not the case here: Kenny G's items are in storage, and the house is adorned with Bezos and Sanchez's own furniture.

Capitalizing On Rising Rents

According to the New York Post, Kenny G bought the six-bedroom house in 1998 for $12.5 million. The musician then purchased the adjacent lot in 2000 and built another 3,500-square-foot house. The construction cost him around $3 million.

Considering that the property is bringing in $600,000 in rent per month — that's $7.2 million a year — it's a pretty good investment by the musician.

For most Americans who rent, the monthly payment isn't nearly as high as $600,000. But the amount has been on the rise.

According to the latest consumer price index (CPI) report, rent for a primary residence in the U.S. rose 8.7% in May from a year ago. Looking further back, you'll see that rent for a primary residence has increased by nearly 60% since 2010.

This uptrend has created an increasing rental income stream for landlords.

But it's not easy to be a landlord these days. Home prices are elevated, and rising interest rates mean buyers have to grapple with larger mortgage payments. And when you buy a house, you have to factor in more than the mortgage payments. Homeowners are also on the hook for property taxes, insurance, maintenance and repairs.

But these days, you don't need to be a landlord to start collecting rental income. New companies — including one backed by Bezos — have innovated ways for people to earn passive income in the real estate market. Here's how to invest in rental properties with as little as $100 while staying completely hands-off.
