How People Make Money Renting Out Spare Rooms

Renting out spare rooms has become one of the easiest and most practical ways to earn extra income, especially as living costs continue to rise. Across the U.S., more homeowners and renters are turning unused space into a steady cash flow.

Why Renting Spare Rooms Is Growing

     The demand for affordable housing has increased significantly, pushing more people to look for shared living options. At the same time, property owners are realizing they can turn empty rooms into income.

Recent data shows that the number of homeowners renting out spare rooms has surged by over 90% in recent years, highlighting how popular this trend has become. 

How Much Money Can You Make?

Income varies depending on location and type of rental, but many people earn:

$900 – $1,600 per month in some U.S. cities 

Up to $2,500 monthly in high-demand areas or short-term rentals 

This makes it a powerful side hustle—or even a full-time income stream.

Ways to Rent Out Spare Rooms

1. Long-Term Rentals

Renting to a tenant for several months or years provides stable, predictable income.

2. Short-Term Rentals

Platforms like Airbnb allow homeowners to rent rooms nightly, often earning more per day than long-term rentals.

3. Co-Living Arrangements

Some homeowners live alongside tenants (“live-in landlords”), sharing space while splitting costs.
