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.
#41 is not accurate at all. There are a ton of safety and sanitation regulations that come with operating a salon out of your home. You need to have several licenses, not the least of which includes a cosmetology or barber education. While laws vary from place to place, it is important to do research before deciding to do something like that. Charging people to cut their hair without proper education and preparations is incredibly irresponsible.
Write academic papers. There are lots of people, from middle school students to people working on their doctorate, who have more work than they can handle. You can get paid to do it for them! Writing other people's school papers can be a great way to make money if you're a good writer and willing to learn lots of different subjects. There are many companies that provide this service for which you can work if this is what you want to do.
Nice writing style Ben. I’m finding out very quickly that to make any money writing, you have to read, read, and then read some more, no matter how smart you feel you are on a subject, before writing your first sentence. I have always been a fan of multiple income streams and am thrilled by the ideas of proofreading, editing, blogging, freelancing and transcribing. Having spent one of my careers doing just that for a large corporation, it’s a perfect fit, but now I can get credit for my work, thanks again for a great article.
Recording Others’ Work. If you’re a trained voice actor or narrator, or you think you have what it takes to break into the niche, you can use ACX and other outlets to find audiobook recording jobs. You’ll need to audition for each role, but once you land a gig, you’ll earn money two ways: at an agreed per-hour rate for the actual job and a shared royalty arrangement with the rights-holder and others involved in the production. If you’re a union actor (SAG-AFTRA), you’re required to charge a minimum fee (variable, but above $200) per finished hour (roughly two studio hours). On a 10-hour audiobook, that’s a minimum payday of $2,000 before royalties.

Jumping into the field is relatively simple. Most prospective transcriptionists start by taking an online transcription course that teaches them the skills necessary to perform common job duties. Companies, such as Transcribe Anywhere, offer classes that teach students the basics of general, medical, or legal transcription, and just as importantly, how they can go about finding clients for work.

Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
