New-Foundation-2563Garage Space Renter $125 per month (for 4+ years)

Someone on Reddit asked for the most “set it and forget it” income idea.

One response…

I have a two car garage. I only use one side of it. I rent out the other side to a guy who parks his sports car in there for $125 a month.

He has come to drive it twice in 4 years and I’ve made 5k+ on it now. Obviously I’ve gotten lucky with who it is and them never coming but it’s extremely passive.

That’s $125/month for doing absolutely nothing

And this isn’t unusual – sports car owners, classic car collectors, and seasonal vehicle owners all need covered storage.

Sites like Neighbor.com make this easy to set up. It’s the biggest peer-to-peer storage marketplace in the US, and a single garage bay typically lists for $100 to $200/month

Don’t have a garage?

Try this

Post on Nextdoor or knock on doors offering to manage other people’s unused garage space. You handle the listing, vet renters, and split the revenue 50/50.

Ten garages at $150/month each = $750/month for yourself. Basically Airbnb co-hosting for garages

Jessica DanteLondon Travel YouTuber ~$400K yearly from travel guides (est.)

Jessica Dante quit her corporate social media job, tried blogging, then noticed her London videos were crushing everything else on YouTube.

I was like, I’m not actually reading any blogs. I’m watching a ton of YouTube content every day.

So she switched to video. One early upload – “10 important things to know before you visit London” – cleared 1M views

She narrowed the whole channel to just London. Counterintuitive, since travel creators usually chase variety.

But London pulls in millions of trip-planning tourists a year, the content’s evergreen, and she never has to go far to film.

She calls these viewers a “drive-by” audience…

They’re the ones that are actively planning a trip… they’re more likely to buy our travel guides, convert with brand partners, and click affiliate links.

Jessica’s business today: 364K YouTube subs, 6M monthly social reach, an 85K email list, and a shop full of $45–$150 London travel guides.

15,000 guides sold since 2023.

At an $80 average price, looks like ~$400K/year from those alone.

Pick a popular destination city – eg. New York, Nashville, Mexico City – produce helpful videos for tourists, and have travel guides ready for them to buy

PostExpensive2418AI Music Channel Operator $1,000 monthly across 5 channels

PostExpensive2418 shares his setup…

Each channel brings in around $195–$200 per month. It’s not a massive income, but considering the low effort involved and the fact that it’s relatively consistent, it’s been surprisingly worth it.

That’s ~$1,000/month.

He runs 5 “artists” – 2 instrumental, 2 nightcore, and 1 covers channel. AI-generated tracks get distributed to Spotify via DistroKid + uploaded to YouTube as faceless music videos

The workflow

I usually take 1–2 days to prepare all the songs (around 60–80 tracks). I edit everything (which takes the longest, about a week for all the material) and schedule automatic uploads of at least 3–5 videos per day. I do this for all my channels.

Total tool stack: Suno, DistroKid, CapCut, Canva. Roughly $10-15/month all-in.

Pattern recognition from his uploads…

Covers of Hot 100 songs pull the most reachInstrumental beats earn the most per minute of effortNightcore “hits a good niche”

Took him ~6 months of consistent uploading before anything clicked – one track randomly went viral on TikTok and pulled everything else into motion.

Pick a niche, give it a few months, see what sticks

Yandi LatinoTikTok Shop Affiliate $1.16M March 2026 TikTok Shop sales

You don’t need to go viral to print money on TikTok Shop.

Yandi Latino came in 5th in the March 2026 creator rankings, generating $1.16M in revenue with just 12.3K followers

With the lowest follower count in the top five, the account generates revenue on par with creators carrying three to fifteen times as many followers, driven by a comparatively small number of high-conversion transactions.

He did it on 3.86K items sold – about $300 average per item, mostly via live streams.

And he’s not the only small fish printing money

7 of the top 10 have under 55K followers6 of the 10 were first-time entries this monthMost of these accounts only opened in late 2024 or early 2025

Shark vacuums – an affordable Dyson alternative – are the secret weapon, featured by 5 of the top 10 creators.

At ~13% commission, Yandi personally cleared around $150K last month.

Five US states just legalized cash-pay stem cell therapy

Wyoming, Utah, Florida, Connecticut and Texas all gave doctors the green light, and a wave of cash-pay regenerative clinics has followed.

Tim Stoddart breaks down the opportunity…

We are witnessing the ‘Cannabis-ization’ of stem cells: states are bypassing federal bottlenecks to create ‘Medical Sanctuary Zones.’

Patients used to fly to Panama and drop $20-50K out of pocket for these treatments. Now they’re getting them stateside.

The clinic economics…

A high-end regenerative clinic can generate between $150,000 and $400,000 per month in revenue. Because these are largely ‘cash-pay’ procedures, margins often exceed 60%.

Tim sees 4 plays for non-doctors who want to ride the wave…

A marketing agency for clinicsA concierge platform charging referral fees per bookingA GMP-certified processing lab (the “shovels” play)Supplements that “prime the niche” pre-procedure

For solopreneurs, the most achievable is probably a state-specific directory – think “Best Stem Cell Clinics in Florida” – ranking for buyer-intent keywords and charging clinics per qualified lead

Kip RolandLive Selling Reseller $12,000 monthly profit

Kip Roland’s Amazon business got suspended at the worst possible time…

I was literally in the hospital. My wife had just had the baby and Amazon is calling me about my account.

So he bought a load of kitchen appliances – under $5/unit, Macy’s customer returns – and went live on Whatnot with zero followers.

It was a total leap of faith. I was like, we’re probably not going to sell anything.

He sold 150 items in under two hours

Ten months later? $450,000 in revenue, ~$100K profit. He now averages $680 profit per 4-hour stream – roughly $170/hr.

The trick is sourcing high perceived value items cheap. He buys returns from major retailers at up to 90% off through B-Stock…

Buy with math, sell with emotion. There’s no better example than live selling.

He’s not alone

Shannon Jean made $557K profit flipping luxury handbags from Costco liquidation auctions solo.

Another reseller, Joe Earl, bought 600 pressure washers in 10 months – never used one before – now heading for six figures.

You could start this weekend with stuff you already own

GianiATM Route Operator $35,000 monthly revenue

Giani used to be a full-time police officer.

Then he noticed people at his local gas station always using the ATM for lottery cash. He asked the owner who owned it…

some dude that comes in a pickup truck.

So Giani got his own machine. Then another. Then another

Today he runs 83 ATMs across multiple states, earning $35,000/month in surcharge fees. All managed from his phone

He notes the advantages of owning ATMs vs vending machines…

My inventory is cash and all I’m literally doing is recycling. I don’t have to go to Costco, BJ’s, pick out whatever flavor people want. I don’t have to deal with health inspectors.

A machine costs about $2,800. Internet box is $10/month. And the cash you load? It cycles back to your account when customers withdraw.

His barber shop location nets $340/month after expenses. His best spot – an ATV rental place – pulls in $3,000 to $5,000/month.

Bad location? No problem…

ATM is a movable asset. You could just move it from location to location till you find a good one.

He also hires “loaders” for remote machines – they use their own cash and earn $1 per transaction. One convenience store 2,000 miles away nets him $740/month – completely hands-off

Your local barber shop or nail salon probably doesn’t have an ATM yet

JoshPostcard Ad Broker $40,000 year one revenue

Josh, a 25-year-old in Utah, sells ad spots on shared postcards to local businesses – one plumber, one landscaper, one bakery, etc.

He ships the cards to 1000s of local homes via USPS’s Every Door Direct Mail tool – no mailing list needed.

Unit economics on a 10K-home card

$2,500 postage (25¢/home)$2,300 printing$9,000 to $10,000 in ad sales (16 spots, $350 to $1,000 each)$4,000 to $5,000 profit per card

He fills the spots by posting weekly in local Facebook business groups…

I probably close 95% of my deals over messenger or text.

His first-ever sale was a plumber paying $1,100 for a premium spot after just 5 DMs.

Year one: ~$40K revenue. Started under $100, no website, no LLC for the first two cards, no employees.

You could start this for free if you really wanted to.

Worth a swing in any US town with a post office and a Facebook group

Kim GreeneProtection Dog Breeder & Trainer $2,970,000 total income (2024)

Kim Greene breeds and trains protection dogs for wealthy families.

Every dog costs $175,000

She explains…

This is not a product that’s for everybody. It just isn’t. In fact, usually I’m trying to talk people out of it to see how much they really want it.

Each dog goes through 2 years of training – protection, obedience, socialization, ~20 commands – then gets hand-delivered to the buyer’s home

Kim started the business in Kenya back in 2005. She’d been living in Nairobi, got pregnant, and didn’t want a firearm or bodyguard for safety – so she got a Dutch Shepherd instead.

She now runs a 170-acre ranch in Montana with ~13 trainers on staff.

In 2024, the business brought in $2.97 million in revenue

You don’t need to become an expert dog trainer to take advantage here.

Lots of dog trainers already have the skills required but struggle with the marketing side – that’s where you could help

Puzzleheaded_Ad_4478Vending Machine Operator $1,450 monthly profit

Puzzleheaded_Ad_4478 shared 20 hard lessons from running a vending machine business on the side…

Right now, I’m making about $1,450 a month (in profits) on average, with 3 machines and a good system in place to make it passive.

That’s about $483/month per machine. But the “passive” part comes with a big asterisk.

Vending is NOT fully passive income.

I’d call it semi passive, like 70% passive.

From time to time, you clean, fix bill acceptors, deal with jammed candy, haul heavy change, drive between locations, and get calls at 7PM because a machine ate someone’s dollar…

A few of the sharpest tips

Always pair snacks with drinks. People want a drink with their chips.Card readers are mandatory. Without one, you’ll make half what you could.Avoid Costco-brand snacks. No one pays premium for a brand they buy in bulk.Stick to a minimum location size. Small offices take the same drive time for way less revenue.

A combo snack-and-drink machine runs $2,500 to $5,000, plus a few hundred for a card reader and initial stock.

Starter move: one used machine in a 20+ person workplace (gym, factory, auto shop), with a small commission to the owner
