Look, I know it’s not always realistic to pull these off; I personally wouldn’t bother trying. But if you’ve got a ton of stuff lying around — not outright junk, but stuff you don’t need, like the aforementioned DVDs and kid’s clothes — it’s worth a try. Advertise on Craigslist and put up signs in your neighborhood, then come Saturday haul a table out to your driveway (assuming you have a driveway), load it up with stuff for sale, and take whatever you can get.
People are always looking to have their cars washed and detailed. You could be a mobile car washer and detailer without having a permanent location. Reach out to people you know or make some flyers and put it in your neighbors' mailboxes. If you want to get serious about it, prop up a one-page website or give out business cards. You can make money quickly doing this.
Find a profitable niche: We’ve talked about this a lot. But, where are you most comfortable. What niche do your skills, values, and interests intersect? Do you have 10 years of experience as a technical writer? Do you have long-standing PR relationships that’ll be invaluable in helping startups launch a successful crowdfunding campaign? Determine what makes your value unique, and lean heavily on showcasing that strength to your potential clients.
Selling clothes you no longer wear is a quick way to make some money. Start with local consignment shops for faster cash, or use sites like ThredUp and Poshmark to find buyers. If you go the online route, be sure to take clear, well-lit photos of your pieces and research similar items to set competitive prices. Get tips on how to sell your clothing.
Hold a yard sale. If you have a yard or garage and plenty of items to sell, you can have a yard sale as early as tomorrow. By advertising your sale on local Facebook pages and Craigslist, you can also skip the paid newspaper ad and keep all of the profits for yourself. If you don’t have time to price everything, try asking patrons to “make an offer” or grouping similar items on tables with an advertised price (e.g. everything on this table is $5).
In 2017, there were almost 90 million pet dogs in the US. Which has opened up a huge opportunity to make money online as a dog watcher or sitter. Specialized sites like Rover or Care.com connect pet owners with pet walkers, sitters, and boarding houses to help look after their best friends when they’re at work or on a trip. If you’re an animal lover, you can make extra money and get to spend some quality time with a furry friend.
If you don’t live in a bottle deposit state, you can still cash in on recyclables by selling scrap metal. You may not have enough soda or beer cans lying around to make this worthwhile — and steel prices are so low right now, it’s not really worth the bother to go collecting them. But if you do have a lot of aluminum cans on hand, or if you have any scrap metal with copper in it, find a local recycling center and see what you’ll get (prices vary wildly by market). Still, unless you have a lot of copper pipes lying around the garage, or bags and bags and bags of old soda cans, realistically, we’re probably talking about getting $5 to $20 back.
