“Invert, always invert.” That nugget of wisdom comes from Carl Jacobi, by way of Charlie Munger, and it’s an idea so simple yet profound that it can steer your life—or in this case, your investments. Instead of teaching you how to succeed in the short-term rental (STR) game, I’m going to show you the surefire way to fail miserably. If you want to lose sleep, empty your bank account, and learn how to turn $100,000 into $1,000 faster than you can say “Airbnb,” read on.
This isn’t just a list. It’s a masterclass in failure. Let’s dive in.
1. Run the Most Optimistic Numbers Possible
Why plan for worst-case scenarios when you can ignore them entirely? Assume your property will be booked 100% of the time at premium rates. Forget about seasonality—your beach house in Maine will definitely be fully booked in February, right? If reality doesn’t align with your spreadsheet, that’s not your fault; it’s reality’s fault.
What you should do instead: Build three projections—best case, worst case, and base case. And for the love of cash flow, assume some months will be slower.
2. Work with an Agent Who Knows Absolutely Nothing About STRs
STRs are complicated: zoning laws, permitting requirements, HOA restrictions. Who needs an agent who knows about any of that? If they start offering advice like, “This area has a moratorium on short-term rentals,” run. You want someone who shows up to the deal with Google Maps open and asks, “Wait, which one’s the ocean again?”
What you should do instead: Hire an agent who’s fluent in STRs. They should know local regulations, optimal areas, and even what amenities get you 5-star reviews.
3. Don’t Factor in Expenses (Other Than the Mortgage)
Expenses are for nerds. Just look at the monthly mortgage payment and call it a day. Ignore cleaning fees, maintenance, property taxes, HOA dues, or utilities. When those bills start rolling in, just pretend they’re junk mail.
What you should do instead: Be granular. Estimate everything: insurance, taxes, cleaning fees, even replacement costs for all those wine glasses guests will break.
4. Ignore Local Laws (or Better Yet, Break Them)
STR regulations are just suggestions, right? Operating illegally adds that extra layer of excitement to your portfolio. The fines? Think of them as “spontaneous property taxes.”
What you should do instead: Research STR laws before you buy. Better yet, hire an attorney or consultant who can walk you through compliance. Avoiding fines is way more fun than paying them.
5. Have No Plan for Management
Whether you’re self-managing or hiring a property manager, wing it. Wait until the day after closing to Google “how to manage an Airbnb.” Sure, that means you might miss out on bookings—or accidentally double-book the same weekend. Chaos is part of the adventure.
What you should do instead: If you’re self-managing, research automation tools, guest communication best practices, and pricing strategies. If you’re hiring a manager, vet them before you buy.
6. Buy with Your Heart, Not Your Brain
Picture this: You walk into a home, and the smell of cookies wafts through the air. You’re in love. Never mind that it’s $100,000 over budget and five miles from the nearest attraction. Buy it. The mortgage is only 30 years long—plenty of time to figure things out.
What you should do instead: Treat your STR like a business decision. Run the numbers, check the comps, and only pull the trigger if it pencils out.
7. Make Zero Improvements
Why spend money on upgrades when you can keep that 1994 decor? Those fluorescent lights and beige walls have “charm.” If your nightly rate tanks, blame the guests for lacking taste.
What you should do instead: Invest in upgrades that increase your property’s appeal—think modern design, smart amenities, and little extras like a stocked coffee bar or a fire pit.
8. Underestimate Time Commitment
Managing an STR is passive income, right? Wrong. But for the purpose of failing miserably, tell yourself it’s “set it and forget it.” Answering guest messages at 2 a.m. builds character. So does rushing to replace a broken water heater mid-checkout.
What you should do instead: Treat it like a business. Outsource tasks where possible and plan for surprises.
9. Overleverage Yourself
When in doubt, max it out. Stretch every penny you have across as many properties as you can. Forget about cash reserves or emergency funds. What’s the worst that could happen?
What you should do instead: Keep reserves for unexpected repairs, slow seasons, or—heaven forbid—an economic downturn.
10. Skip the Market Research
Why analyze the market when you can just assume people will love your property? Blind optimism is faster than due diligence. Bonus points if you buy in a town with no tourism industry.
What you should do instead: Study occupancy rates, average nightly rates, and demand drivers in your market. Make sure there’s actual, repeatable demand.
Final Thoughts
Here’s the thing: If you want to lose money in STRs, follow this guide to the letter. But if you’d rather make money, do the opposite. Plan for the worst, hire experts, and treat your STR like a business, not a fantasy.
Failing is easy, but success? That takes work. And the reward? Freedom, cash flow, and maybe even the occasional margarita by your own STR’s pool. Cheers to doing it the right way.
