1. Buying concession land thinking it's titled beachfront
The first 200 meters from the high-tide line is the Maritime Terrestrial Zone (ZMT). The first 50m is public; the next 150m is concession — a municipal lease, not fee-simple ownership. Foreign ownership of a concession is capped unless you've met residency rules.
Marketing says "beachfront." The registry says concession. Read /guides/costa-rica-maritime-zone-concession-explained before you wire a deposit on sand-adjacent dirt.
2. Skipping due diligence on title, water, and permits
No independent attorney, no folio real lien check, no matching plano catastrado, no carta de agua from the ASADA — these are how deals blow up after closing.
Run the full checklist in /guides/costa-rica-due-diligence-checklist. Water is the silent deal-killer in coastal Guanacaste: no legal supply, no build, no STR.
3. Believing broker gross revenue on the listing PDF
Peak-season gross from a villa two kilometers closer to the beach is not your inland comp. Gross is not net — strip platform fees, management, utilities, HOA, and 13% IVA before you compare to ask price.
See Costa Rica Airbnb investment: real numbers and rank listings against nearby Airbnbs on the map.
4. Ignoring STR registration and tax from day one
Opening Airbnb without ICT lodging registration, a NITE, and IVA filing is a liability that compounds — and shows up at sale.
Budget the flat-or-profit income-tax choice and monthly IVA from your first booking. Details: /guides/costa-rica-str-tax-registration-2026 and /guides/costa-rica-property-taxes-for-foreigners.
5. Wrong micro-location inside the right town
Playas del Coco, Flamingo, and Tamarindo are not uniform markets. A home a five-minute drive inland can earn 30–50% less than a walk-to-beach twin — same town name, different product.
Pin-level location beats brochure adjectives. Use town hubs and the listing map; compare within a few hundred meters, not across the whole bay.
6. HOA / condo rules that ban or cap STR
Gated communities and condos can restrict nightly rentals, cap keys, or require hotel-style licenses you cannot get. Read HOA minutes and rental clauses before offer — not after your manager promises "everyone does it."
See /guides/condo-vs-villa-airbnb-guanacaste for when condo economics win anyway.
7. No exit plan or liquidity reality check
Buyers fall in love with yield and forget days-on-market on luxury inventory. The Gold Coast is a strong rental corridor — not every price tier resells in 90 days.
Model capital-gains exposure and closing costs on exit: /guides/costa-rica-property-exit-capital-gains. Thin liquidity at the top end is normal, not a personal failure.

What is the biggest mistake foreigners make in Costa Rica real estate?
Skipping independent due diligence — especially confirming fee-simple title vs maritime concession, legal water (ASADA letter), and liens on the folio real. The second is trusting gross STR revenue from the wrong comps.
Is Guanacaste safe for foreign property buyers?
Yes, with proper checks. The system works when you use an independent attorney, verify registry and survey, confirm water, and model net yield from nearby rentals — not when you rush a deposit to hit dry season.
Do I need a Costa Rican corporation to buy?
No — foreigners can hold fee-simple title personally. Many still use an S.R.L. for liability and rental administration; it adds annual entity tax and accounting cost. See /guides/can-a-foreigner-buy-property-in-costa-rica.
How do I avoid overpaying for STR potential?
Rank the ask against trailing revenue from successful nearby Airbnbs on the same geo tier (walk vs inland). If comps are thin, treat any yield estimate as rough only — not a steal.
Can any home be an Airbnb in Guanacaste?
No. Zoning, HOA rules, water, ICT registration, and parking/access all gate STR use. Confirm all five before you buy for income.
Should I buy beachfront or ocean view?
Beachfront and true walk-to-beach command premiums but carry concession risk near the ZMT. Ocean view inland can yield well at lower basis — if view and pool recipe match comps. See /guides/beachfront-vs-ocean-view-returns-guanacaste.
