Bounce house / party rental
Run a local party rental business (bounce houses, tables, tents) monetized via per-event bookings.
The idea, in plain language
Run a local party-rental business (bounce houses, tables, tents, outdoor movie screens, cornhole, mini-golf, even commercial kitchen equipment and chicken coops) monetised per event. Koerner dominates the idea with Castles of Dallas ($1,600 buy-in, claimed first-month payback, two inflatables to 40+ units), Backyard Movie Theater, Event Kitchens Charleston ($337k/year renting to caterers), Brandon Doyle's five offline hustles, a temporary-fence rental sold for $600K, and Tim's $2,600/week RC-construction-trailer events business. MFM adds city/corporate tour businesses (~$1M/year), the Museum-of-Ice-Cream experiential format, Nick Gray's $100-party method and Rent the Chicken. Customers are families, schools, weddings, HOAs and caterers; startup cost ranges from $1,600 (used inflatables) to $10-11K (RC trailer) to warehouse-hacking scale; cited revenues are $337k/year, $2,600/week, '$10K in a year/month/week/day', and ~$1M/year for city tours.
Where the sources agree
- Used-equipment sourcing on Facebook Marketplace is the entry playbook - the Castles of Dallas bounce house story, Brandon Doyle's liquidation rugs, and other Koerner episodes all start with cheap used gear bought direct.
- Pick one tight vertical (party inflatables, movie nights, caterer kitchens, RC trailers) and dominate it - Koerner repeatedly pushes niche focus over breadth.
- Add-ons and second revenue streams beat the headline product - LED dance floors, manufacturing repairs, tent/table rentals, premium indoor upgrades all lift average booking value.
- Validate with a small first booking (HOA, friend party, county fair) before scaling inventory.
Where they differ
- Koerner owns the operator playbook (Castles of Dallas, Derek's movie theater, Event Kitchens, Brandon Doyle, Tim's RC trailer, fence rental, dumpster rental), while MFM pitches it as an idea list (city tours, Museum of Ice Cream, Rent the Chicken, $100 party) without operator breakdowns.
- Capital intensity ranges widely: $1,600 used inflatables (Castles), $10-11K RC trailer (Tim), $337k/year catering-equipment operation (Event Kitchens), $600K exit on a temporary-fence rental, ~$1M/year city tours - the videos disagree on whether this is a side hustle or a full-time operation.
- Revenue framing differs - Koerner quotes operator revenue ($337k/year, $2,600/week, '$10K a year/month/week/day'), MFM quotes category revenue (NYC tours at $1M/year) without unit economics.
- Customer mix spans B2B (caterers for Event Kitchens, contractors for dumpsters, corporate events for tours) and B2C (parents, schools, HOAs) - the videos do not converge on the better segment.
