You don’t have to find a long-term tenant to earn income from your home’s unused square footage. Apps like Airbnb, Vrbo, and HomeAway let you rent out your home to business and leisure travelers on a nightly or weekly basis. Depending on prevailing rents in your local market and your space’s size, amenities, and privacy, you could earn anywhere from $40 or $50 to $500 or more per night.
Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.
