🇨🇷 Tai — Costa Rica
1. Airbnb and Booking Must Now Report to Costa Rica's Tax Authority
Starting March 2026, platforms like Airbnb and Booking.com are required to report all vacation rental activity to Costa Rica's Ministry of Finance (Hacienda). Hosts must be registered as taxpayers, issue electronic invoices, and charge 13% VAT to guests. Additionally, a new 12.75% tax on gross rental income will be automatically withheld by the platforms.
Sources:
Why it matters:
- Agencies advising property owners with vacation rentals should update their value proposition — tax compliance is now a differentiating service.
- Owners who fail to register with Hacienda face fines of 2% of the prior year's gross income.
2. 📉 Guanacaste: 31% Correction Opens a Buyer's Window
After the pandemic boom that drove prices up 400% between 2020 and 2023, Guanacaste's market saw a 31% year-over-year correction. Average prices sit at $1,530/m², with luxury properties staying on market for an average of 340 days. Communities like Tamarindo, Potrero, and Playa Flamingo are holding value best.

Why it matters:

- 8-12 months of inventory supply suggests a market that rewards patient, well-advised buyers.
3. 🏗️ GAM: Apartment Prices Surge 20% Year-Over-Year in San José
Apartments in San José now average $2,701/m², a 20% year-over-year increase that makes the capital one of the fastest-appreciating markets. Escazú, Santa Ana, and La Sabana lead demand, driven by both local and foreign buyers. The average apartment in the Greater Metropolitan Area (GAM) is priced around 90 million colones (~$180,000).
Sources:
Why it matters:
- For agencies in the GAM, the apartment segment offers the highest activity and commission potential.
- The price gap between apartments ($2,040/m²) and houses ($1,270/m²) continues to widen.
4. 🏠 Buy or Rent in 2026? The Numbers Speak
El Financiero published a detailed analysis comparing buying versus renting in Costa Rica. For a 120 m² home valued at $150,000, with a mortgage at 8% over 30 years, the monthly payment comes to roughly $1,101 — very close to the average GAM rent of $1,200. Mortgage rates in Costa Rica range from 7.25% to 9.25% depending on the bank and term.
Sources:
Why it matters:
- Agencies that can present clear comparative data will be better positioned to advise clients torn between buying and renting.
- With variable rates, the timing of a deal can significantly impact the client's monthly payment.

1. 💰 US Mortgage Rates Drop Below 6% for the First Time in 3.5 Years
The average 30-year fixed mortgage rate in the US fell to 5.90% in early March 2026, the lowest level since September 2022. The Fed held rates at its first 2026 meeting (target range 3.50-3.75%), but markets anticipate three more cuts to reach 3.25-3.50% by year-end.
Sources:
Why it matters:
- Lower US rates increase purchasing power for North American buyers looking at Costa Rica properties.
- Refinance volume grew 15% year-over-year, freeing up capital that may flow into international real estate investments.
2. 📊 Housing Prices Rise in 86% of Global Markets
According to JLL, nominal housing prices grew 2.4% year-over-year across 55 monitored markets, with 86% showing positive trends. However, real growth adjusted for inflation remains near zero (-0.1%), suggesting appreciation barely offsets purchasing power erosion.
Sources:
Why it matters:
- Positive nominal growth maintains sector appeal, but real returns depend on markets with appreciation above local inflation.
- Costa Rica, with 4-8% annual appreciation projections in well-located areas, positions favorably.
3. 📈 Real Estate Capital Markets Gain Momentum in 2026
The commercial real estate investment environment strengthened notably in H2 2025, and momentum is expected to continue into 2026. Debt markets remain very active and transaction volumes are expanding, supported by low or falling interest rates, contained inflation, and increased fiscal spending.
