How Occupancy Rate Assumptions Destroy Airbnb Pro Formas

Most real estate blogs will tell you a Las Terrenas condo can pull $40,000-$50,000 a year on Airbnb. They're wrong, and the mistake almost always traces back to a single cell in a spreadsheet: the occupancy rate assumption. Change that one number from 70% to a realistic 46%, and a pro forma that looked like a slam-dunk investment turns into a property that merely covers its costs.

This isn't a hypothetical. It's the exact exercise worth running before anyone commits six figures to a pre-construction unit on the strength of a developer's income projection.

01What's a Realistic Airbnb Occupancy Rate in the Dominican Republic?

For a standard two-bedroom condo in Las Terrenas, realistic annual occupancy runs 44-48% on a market-average basis, with a conservative floor near 35% and an optimistic ceiling around 56% for well-managed, well-reviewed listings in strong locations. That's the range behind Evalúa's market model as of May 2026 — not the 65-75% figures that show up in developer sales decks, which describe peak-season performance stretched across the whole year.

The gap between those two numbers is where most pro formas quietly fail.

02Why Developers and Agents Default to High Occupancy Numbers

A higher occupancy assumption makes any property look like a better investment, and nobody auditing the pitch deck is checking it against real booking calendars. Developers selling pre-construction units have every incentive to present the most flattering case: a bigger projected income number justifies a bigger price tag and makes the CONFOTUR tax savings look even more compelling by comparison. An agent earning commission on the sale isn't the one who has to live with the actual bookings 18 months later.

The honest version of occupancy in a tourism market like Las Terrenas looks more like a bell curve than a flat line. December through March fills up — Dominican and European high season overlaps, and well-run listings can hit 70-80% occupancy those months. May, September, and October are a different story: 20-30% occupancy isn't unusual, and some weeks sit empty entirely. Average the good months against the bad, and you land in the mid-40s, not the high-60s.

This seasonality problem is one reason an Airbnb income calculator that uses a single flat annual rate can still mislead you — it's the averaging, not the headline number, that has to be right. Run your own numbers through Evalúa's calculator with a realistic range rather than a single optimistic figure, and you'll see the swing between scenarios immediately.

03Rebuilding the Pro Forma: A Worked Example

Take a $320,000 two-bedroom condo in central Las Terrenas, roughly 95 m² — close to the zone's core-area median of about $2,225/m² for condos (n=230, Evalúa listings, October 2026). A typical developer pro forma for this unit might claim $45,000 in annual gross Airbnb revenue, built on a 70% occupancy assumption at an average daily rate of about $176. Here's what happens when you rebuild it with the Las Terrenas market average instead.

*Carrying costs assume HOA at $300/month ($3,600), insurance at $1,200, IPI on value above the ~$182,000 threshold (1% × $138,000 = $1,380), 1% maintenance ($3,200), plus roughly half of annual utilities during vacant periods — about $9,900 combined for this property.

The developer's version shows $24,750 in annual net cash flow — an eye-catching 7.7% cash-on-cash return before financing. The rebuilt version shows roughly $4,730 — about 1.5%. Same unit, same ADR, same costs. The only thing that changed is the occupancy assumption, and it cut projected profit by more than 80%.

Neither number is "the" true return — actual performance depends heavily on the specific unit, its reviews, its management, and how aggressively it's priced. But the realistic range is the one a buyer should underwrite against, because it's the one a bad booking season actually delivers.

04What Occupancy Rate Mistakes Cost You Beyond Year One

An inflated occupancy assumption doesn't just overstate year-one income — it compounds into every downstream decision in the purchase. Buyers who budget against a 70% occupancy figure tend to stretch further on purchase price, finance more aggressively, and skip a cash reserve for the slow months, because the spreadsheet told them the property would carry itself.

When actual bookings land at 40-50% instead, the shortfall usually surfaces at the worst possible time — during the April-to-October stretch when a property manager is calling about a special assessment or a roof leak, and the owner discovers the "passive income" property is actually running a deficit. That's the scenario this site's guide on property management costs in the DR walks through in more detail: a 20% management fee on an inflated revenue number looks trivial; on the real number, it's the difference between a property that pays for itself and one that doesn't.

05How to Stress-Test an Occupancy Assumption Before You Buy

Ask for month-by-month occupancy data, not an annual average, and run three scenarios — conservative, base, and optimistic — rather than trusting a single number. A seller or agent who can't produce monthly booking history for a comparable listing is asking you to trust a guess.

Three checks worth doing before you believe any projected number:

1. Ask for the seasonality curve, not the annual figure. A real host or property manager can show you occupancy by month for an existing unit in the same building or sector. If nobody can produce that, the annual number is fabricated.
2. Cross-check against Evalúa's published range. The 35-45-56% conservative/base/optimistic band for Las Terrenas is a reasonable sanity check for any standard condo pitch — a number well outside that range needs a specific explanation (direct beachfront, unusually large unit, exceptional review history).
3. Model your own numbers before you model theirs. Run the property through the Evalúa Property Analyzer and the Rental Income Calculator with your own assumptions, then compare that to what the seller handed you. The gap tells you how much of the pitch is marketing.

If you're comparing markets rather than just one listing, the occupancy assumption matters just as much outside Las Terrenas — see how Sosúa and Cabarete stack up on realistic yield rather than headline income claims. And because there's no MLS equivalent in the DR to cross-check asking prices or performance data independently, the burden of verification sits entirely with the buyer — a problem covered in more depth in this site's guide to verifying a property's price without an MLS.

The Central Bank of the Dominican Republic's tourism data is a useful macro check too: the country logged 11.7 million visitors in 2025, a real and growing number, but national tourist arrivals and a single condo's booking calendar are not the same thing — arrivals data tells you the market exists, not that your unit will capture its share of it.

06Does CONFOTUR Change the Occupancy Math?

No — CONFOTUR reduces your tax bill, not your vacancy risk. The 15-year property tax and rental income tax exemptions (running from completion of construction, under Ley 158-01 Art. 7 as amended by Ley 195-13) make the net number better at any occupancy rate, but they don't change how many nights your unit actually books. A property with a bad occupancy assumption and a CONFOTUR exemption is still a property with a bad occupancy assumption — just one that keeps slightly more of a disappointing number. Run the CONFOTUR Savings Calculator against your realistic occupancy scenario, not the inflated one, to see the exemption's true value.

It's also worth remembering that CONFOTUR benefits attach to the first buyer from the developer and generally do not transfer to a resale buyer — a separate risk from occupancy, but one that compounds if you're underwriting a future exit based on an inherited exemption that may not exist.

07Common Mistakes to Avoid

1. Trusting a single annual occupancy percentage without a monthly breakdown. A flat 65% figure hides a seasonal reality where three months carry the other nine. Always ask how the number is built, not just what it is.
2. Using peak-season ADR with annual-average occupancy. Pairing a December rate with a 70% occupancy rate double-counts the strong months. Match your rate and occupancy assumptions to the same period.
3. Ignoring the gap between gross and net. A 20% property management fee and a 3% platform fee take nearly a quarter of gross revenue before carrying costs even enter the picture. Model net cash flow, not headline income.
4. Skipping a cash reserve for shoulder-season months. Properties with 20-30% occupancy in off-peak months still owe HOA, insurance, and IPI every single month. Budget at least two to three months of carrying costs as a buffer.
5. Assuming last year's occupancy predicts next year's. New supply enters Las Terrenas every season, and a listing's ranking depends partly on reviews and pricing strategy — covered in this site's guide to building a 5-star review history. A strong first year doesn't guarantee a strong third year without active management.
6. Treating the pro forma as the deal, not a starting hypothesis. Even a well-built pro forma is a forecast, not a guarantee — the Dominican short-term rental market is lightly regulated and highly dependent on individual listing quality, management, and marketing.

08Frequently Asked Questions

What is a realistic Airbnb occupancy rate in Las Terrenas?

A realistic base-case occupancy rate for a standard condo in Las Terrenas is roughly 46-48% annually, based on Evalúa's market model as of May 2026. Conservative estimates run closer to 35%, and well-managed, highly-reviewed listings in strong locations can reach 56%, but treating any of these as a flat monthly rate ignores real seasonal swings.

Why do developer pro formas use higher occupancy numbers than actual market data?

Higher occupancy assumptions make a projected income number — and therefore the investment case — look stronger, and the person building the pro forma usually isn't the one managing the property afterward. A 70% occupancy assumption often reflects peak-season performance applied across the full year rather than a realistic annual average.

How much does occupancy rate affect net cash flow on a Las Terrenas condo?

Significantly — on a $320,000 condo, moving from a 70% to a 46% occupancy assumption can cut projected net cash flow by more than 80%, from roughly $24,750 to around $4,730 a year in the worked example above. The same ADR and the same costs produce very different outcomes depending on which occupancy figure you trust.

Does property management fee structure change with occupancy?

The percentage stays the same — typically 15-25%, with 20% as the common midpoint — but the dollar amount scales directly with actual bookings. Lower real-world occupancy means a lower absolute management fee, but it also means lower net income overall, so the percentage itself doesn't offset the shortfall.

Can I verify a seller's occupancy claims before buying?

Ask for month-by-month booking history from the actual unit or a directly comparable one in the same building, not just an annual summary. If no granular data is available, treat the claimed occupancy rate as unverified and underwrite against Evalúa's published market-average range instead.

Does CONFOTUR status improve occupancy rates?

No. CONFOTUR is a tax exemption program under Ley 158-01 covering property tax and rental income tax for 15 years from project completion — it has no bearing on how many nights a unit actually books. Don't let a strong tax story substitute for a realistic occupancy assumption.

09The Bottom Line

The occupancy rate is the single highest-leverage number in any Airbnb pro forma, and it's also the easiest one to inflate without getting caught — until the first full year of actual bookings comes in. Before buying on the strength of a projected income figure, rebuild the pro forma yourself using Las Terrenas market averages, not the seller's assumptions, and stress-test it against a conservative scenario, not just the base case.

The market itself is real: the Dominican Republic drew a record 11.7 million visitors in 2025, according to Central Bank data, and national gross rental yields average around 8.5% per Global Property Guide's Q1 2026 figures. But a healthy market average and a single unit's realistic cash flow are two different numbers, and conflating them is how buyers end up disappointed in month fourteen. Run your own numbers through the Evalúa Property Analyzer before you sign anything, and treat any projection you can't independently verify with the DR's tourism ministry or your own market research as a starting point for negotiation — not a guarantee.
