Hosting on Airbnb offered teachers an average $6,500 of supplemental income, according to the report. Hosts said the extra money helped with bills, retirement savings and vacation spending.
Educators in Wisconsin, Utah and Ohio dominated the report, while city dwellers in New York, Seattle and San Francisco made the highest profits.
Many teachers praised the experience of hosting as a way of meeting people from all over the world and using their teaching skills to share the knowledge.
"But this relationship, even if mutually beneficial, only exists because for so many teachers, their primary career isn't enough to sustain them," The Atlantic's Alia Wong reported.
According to the NCES, 94 percent of public school teachers in the United States spend their own money on school supplies.
And even when adjusted for inflation, teachers last year earned less than they did in 1990.
With rising housing and living coasts from coast to coast, it’s hardly surprising teachers are opting for supplemental income streams.
And hosting on Airbnb isn’t the only way teachers have thickened their wallets.
According to the Atlantic, many teachers in recent years have also started driving for rideshare companies during their free time.
Teachers are also five times more likely than the average American full-time employee to have a part-time job, Vox reported in April.
