Every few weeks somebody forwards me a screenshot. An Airbnb listing near Nosara going for $450 a night, with a note attached: “so this pays for itself in like three years, right?” I love the optimism. Then I do the thing nobody wants me to do. I multiply that nightly rate by the nights it’s actually booked, knock out the stretch of the year the town is half-empty, subtract fees, management, taxes and the maintenance the salt air demands, and hand back a number that’s a lot more grounded.
Vacation rental income in Guanacaste is real. My clients earn it, the buyers I’ve helped earn it, and it can be a genuinely good investment. But the honest version is seasonal, taxed, and lumpier than the brochures let on. Here’s how it actually works.
The seasonality nobody puts in the pitch
Guanacaste runs on two seasons, and your income runs on them too. High season is the dry, sunny stretch from about mid-December through April. Christmas, New Year and Semana Santa (Easter week) are the crown jewels, when a good property commands premium rates and books out weeks deep. That’s when you make your money.
Then comes the green season. May through November brings the rain, and September and October are the quietest months on this coast. Plenty of restaurants in Sámara and Nosara just lock the doors and take the month off. Rates soften, occupancy sags, and the property that felt like a money printer in January can sit dark through October.
This isn’t an argument against buying. It’s an argument against annualizing your best month. The owners who do well budget for the slow stretch and treat the high-season haul for what it is: most of the year’s income showing up in a handful of months.
Gross vs net: where the money actually goes
Gross yield is the number people quote at cocktail parties. Net yield is the number that actually lands in your account, and the gap between the two is wider than newcomers expect. Between what a guest pays and what you keep, you hand over a real slice to:
- Platform fees (Airbnb, VRBO, the booking sites).
- Property management, typically around 15–25% of rental revenue here, and worth it for a remote owner (more on that below).
- Cleaning, laundry, restocking and guest supplies between every single stay.
- Utilities, internet, pool and garden service, HOA fees if you’re in a community.
- Maintenance, the salt-and-humidity tax. On the coast everything corrodes and molds faster. Air conditioners, appliances, hinges, wood, roofs. You repair and replace more often than you ever would back home.
- Taxes, which brings us to the part people love to skip.
I won’t hand you a fake “you’ll net X%” figure, because it swings hard by location, property and how well the place is run. What I’ll tell you straight is that gross yields vary a lot, net comes in meaningfully below gross, and you should run your numbers on the net.
ICT registration and the 13% VAT (this is not optional)
Costa Rica has tightened up on short-term rentals, and you need to operate legally. As the rules stand now, non-traditional lodging like Airbnb-style rentals must register with the ICT (the Costa Rican Tourism Board), and short-term rentals owe the country’s 13% VAT (IVA). You’re also filing income tax on the earnings.
Plain terms: budget for the 13% VAT on top of everything else, get registered, and keep clean books. The days of quietly renting under the radar are closing fast. I’m not your accountant, so please confirm the current requirements with a Costa Rican CPA (contador) and a tax attorney. But go in planning to do this by the book. It’s a lot cheaper than the alternative.
What actually makes a rental earn well here
The properties that outperform aren’t always the fanciest. They tend to share a few honest advantages:
- Location you can walk from, or hop to the beach and town in a couple of minutes. Sámara, Carrillo, Nosara and Tamarindo each pull a slightly different guest, and proximity sells.
- A pool, AC that actually works, fast internet, and real photos that match what guests find when they walk in.
- Great reviews and fast replies. The algorithm and the guests both reward it.
- A manager on the ground to handle the 9pm “the AC stopped” message so you’re not fielding it from another country.
Frequently asked questions
What occupancy rate should I expect in Guanacaste?
It varies widely by town, property and management, and it leans hard on high season. Rather than chase one headline number, model it month by month: strong December through April, thin September and October, and see whether the annual total still works for you. Honest monthly math beats any blanket occupancy figure.
Do I really have to charge 13% VAT and register with the ICT?
Under current rules, yes. Short-term tourism rentals are meant to be registered and to charge the 13% IVA, with income tax on top, and enforcement has been climbing. Treat it as a real cost and a real obligation, and confirm today’s specifics with a local tax professional before you list.
Is a vacation rental a better investment than a long-term rental?
Different animals. Vacation rentals can gross more but cost more to run and swing with the seasons. Long-term rentals earn less per month but stay steady, cost less to manage, and go easier on the property. The right answer depends on your appetite for variability and hands-on work.
The honest bottom line
A Guanacaste vacation rental can absolutely earn its keep. I wouldn’t keep steering clients into them if it couldn’t. But the real return lives in the net, not the nightly rate: seasonal income, real taxes, and constant upkeep against the salt and humidity. Buy on numbers you’ve stress-tested for October, not just January, and you’ll be a happy owner.
