ATM Business
The ATM business is one of those underrated ventures that quietly generate substantial income without much fanfare. Entrepreneurs purchase or lease ATM machines and place them in locations with high foot traffic, such as convenience stores, bars, or event venues.
Every time someone withdraws cash, the owner collects a transaction fee, which can range from $2 to $5 per withdrawal. While the initial investment and setup require some research and capital, the ongoing maintenance mainly involves replenishing cash and occasional servicing.
Many operators outsource cash refills and maintenance, making it almost a passive income stream. What makes this business particularly appealing is its scalability — adding more machines across multiple locations can significantly boost profits, turning a relatively “boring” business into a six-figure income generator.
Laundromat
Laundromats have been a staple business for decades because they fulfill a basic need that is unlikely to disappear anytime soon. They cater to apartment dwellers, college students, and anyone without reliable access to in-home laundry machines. Laundromats typically operate on a self-service model, meaning that labor costs are low. Modern machines have made operations more efficient and reduce water and energy consumption, which helps improve profit margins.
Additionally, many laundromat owners add vending machines for detergents or snack bars to diversify their income. With the right location—close to dense residential areas or universities—and consistent upkeep, laundromats can pull in six figures annually, providing owners with stable, long-term revenue.
Trash Bin Cleaning
Trash bin cleaning is a niche service that might sound unglamorous but meets an important need. Dirty, smelly garbage bins are an annoyance for homeowners and businesses alike, and this service offers a hygienic solution. Typically offered on a subscription basis, trash bin cleaning businesses use high-pressure washers and eco-friendly detergents to sanitize and deodorize bins.
Since few companies offer this service, competition is low, and it’s easy to build a loyal customer base.
The startup costs are modest—mainly requiring a specialized cleaning vehicle or trailer and cleaning supplies. Given the recurring nature of the service and growing environmental awareness, trash bin cleaning can be a surprisingly profitable and steady six-figure business.
Niche Newsletter
With the rise of digital content, niche newsletters have carved out an important role in targeted marketing and community-building. Unlike broad-based publications, these newsletters focus on specific interests or industries—such as rare hobbies, professional development, or hyper-local news.
Because they cater to highly engaged audiences, they can attract premium sponsors and advertisers willing to pay well for direct access. Additionally, many newsletters incorporate paid subscription models for exclusive content.
The costs are minimal, mostly involving time to produce quality content and build a subscriber base. Over time, with consistency and effective marketing, these newsletters can easily bring in six figures annually while requiring little overhead.
Parking Lot Striping
Parking lot striping may not be a glamorous business, but it is essential for safety and organization in commercial and residential areas. Proper striping ensures clear traffic flow and complies with regulations, making this service a must-have for many businesses.
The work typically involves marking parking spaces, crosswalks, and handicap zones, often on a contract basis for property managers and municipalities. While the business may be seasonal in some regions, many areas require striping services year-round due to ongoing construction or repainting needs.
With relatively low startup costs—mainly equipment like striping machines and paint—owners can secure lucrative contracts. Efficient scheduling and reliable service can help generate consistent, six-figure revenues.
Storage Unit Rentals
The storage unit rental business has experienced consistent growth thanks to urbanization, downsizing trends, and increased mobility. People and businesses alike need extra space to store belongings, inventory, or seasonal items. Once a facility is established, the business model is straightforward: rent out units monthly with minimal involvement from the owner.
While initial capital is required to build or acquire storage property, ongoing expenses are low, often limited to property maintenance and security. Modern technology allows for automated access control and billing, which reduces the need for on-site staff.
With a well-located facility and good marketing, storage unit rentals can deliver a steady six-figure income with the potential for expansion.
Local Vending Machines
Vending machines might seem old-fashioned, but they remain a solid source of income due to their convenience and accessibility. Operators select prime locations such as office buildings, schools, gyms, or apartment complexes where people are likely to make quick purchases. A successful vending machine business involves understanding customer preferences, stocking popular snacks and drinks, and ensuring machines are regularly maintained and refilled.
Many newer machines accept credit cards or mobile payments, increasing sales potential. The business requires moderate time investment for restocking and collecting revenue, and scaling by adding more machines can quickly increase profits. With minimal overhead, local vending machines can quietly generate six-figure annual incomes.
Mobile Notary
Mobile notaries provide an increasingly valuable service by traveling to clients to notarize important legal documents like contracts, deeds, and affidavits. Their mobility offers convenience that traditional notaries can’t match, enabling them to charge premium fees, especially for after-hours or urgent appointments.
Real estate transactions, loan signings, and legal proceedings consistently require notarization, ensuring steady demand. While becoming a certified notary involves some training and licensing fees, the overhead remains low—mainly transportation costs and marketing efforts.
The flexible schedule, combined with a network of repeat clients, can help mobile notaries reach six-figure revenues, especially in densely populated or high-demand areas.
Home Inspection
Home inspectors play a crucial role in real estate transactions, helping buyers and sellers understand the condition of a property before a sale. The demand for certified inspectors remains high as homebuyers seek to avoid costly surprises after purchase.
Becoming a home inspector requires training, certification, and attention to detail, but it is a rewarding and lucrative career.
Each inspection can command fees ranging from a few hundred to over a thousand dollars, depending on the property size and market. Successful inspectors often build relationships with real estate agents, leading to steady referral business. With consistent work and excellent service, home inspection businesses can easily generate six figures annually.
Bookkeeping
Bookkeeping services are in high demand among small and medium-sized businesses that need professional help managing their finances but cannot afford full-time accountants. Bookkeepers handle tasks such as tracking income and expenses, reconciling accounts, and preparing financial statements. This service is critical year-round and can be offered remotely, giving bookkeepers flexibility and low operating costs.
With multiple clients, a skilled bookkeeper can generate six-figure incomes by providing timely, accurate services that help businesses maintain financial health.
Advances in cloud-based accounting software have made bookkeeping more efficient, increasing profitability and scalability for entrepreneurs.
Snow Removal
Snow removal is a seasonal but essential service in colder regions where heavy snowfall can disrupt daily life and business operations. Residential homeowners, commercial property owners, and municipalities all need reliable snow clearing for driveways, sidewalks, and parking lots. The business requires investment in equipment like plows, shovels, and salt spreaders, but contracts often yield high returns during the winter months.
Snow removal operators build recurring client relationships through seasonal contracts, ensuring predictable income. Though the work is physically demanding and weather-dependent, the high demand and ability to charge premium rates allow this “boring” business to quietly generate six figures each year.
