Sell Used Items to Locals Online
Selling used items online is one of the fastest ways to earn money in Spain. Buyers are always looking for quality second-hand goods at a fair price.
Popular platforms in Spain include Vinted, Milanuncios, and OLX. OLX supports most legal resale categories, from furniture and electronics to vehicles and video games.

OLX works similarly to Facebook Marketplace or eBay. Items like aquariums, cookware, tables, cars, and video games all sell regularly on the platform.
Always arrange handoffs in public, well-lit locations. Bringing a friend along is a good habit when meeting buyers for the first time.

Teach Spanish Online to Foreign Learners
Demand for Spanish tutors online is strong, particularly from learners in the US, UK, and Brazil. Certification helps, but it isn't required to get started.
Platforms like iTalki and Preply are beginner-friendly and give new tutors access to a large pool of paying students from day one.
Part-time and full-time positions also exist on these platforms, though they typically require a degree in languages or education alongside university-level teaching experience.
Freelancing is the most accessible entry point. Most tutors set their own rates and build up a client base within the first few weeks of listing a profile.
Earn Through Cashback and Referral Programs
Cashback programs generate passive income with no ongoing effort once set up. Returns are modest but consistent, and they add up over time.
Referral programs tend to pay faster. Freecash's referral program pays up to $13 per referred user. Popular Spanish brands like Beruby also run referral schemes worth exploring.
