Buying property in Costa Rica without adequate due diligence is the recipe for serious economic losses: registry problems, hidden litigation, illegal constructions, municipal debts, use restrictions. A professional appraisal is only part; this guide explains complete step-by-step due diligence for 2026 real estate transactions.
The 5 components of real estate due diligence
1. Registry due diligence
2. Municipal due diligence
3. Physical-technical due diligence (appraisal + inspection)
4. Legal-fiscal due diligence
5. Use / neighborhood due diligence
1. Registry due diligence
Verify at National Registry:
- Updated ownership certification (<3 months): confirms registered owner
- Liens (mortgages, pledges, seizures, annotations)
- Limitations (right of way, easements, homestead, family affectations)
- Transfer history: very frequent recent transfers or atypical values can be red flag
- Cadastral plan concordance with real folio: sometimes inconsistency blocks transfer
Cost: $20-$50 USD per property at National Registry.
2. Municipal due diligence
Verify at canton municipality:
- Current property tax declaration and up to date
- Municipal tax current (no arrears): arrears assumed by new owner
- Construction permits granted for existing buildings
- Land use and zoning: what use does the property allow?
- Public services (water, electricity, collection)
- Commercial permit if commercial property
- Current construction line / setbacks
Cost: many municipalities do not charge for the inquiry; others charge a small fee for the certification.
3. Physical-technical due diligence
Professional CFIA appraisal
Determines real market value and detects inconsistencies:
- Property value vs seller’s asking price
- Local market comparables
- Risk factors (seismic, floodable, volcanic zone)
- General structural state
Structural inspection
For used properties (especially >10 years):
- Foundations and structure (cracks, fissures, settlements)
- Roof and utilities (humidity, leaks)
- Electrical and hydraulic systems
- Terrain (drainage, stability)
Real measurement
Verify declared area matches real. Discrepancies >5% justify renegotiating or managing regularization.
Cost: from approx. ₡150,000 (USD 300), depending on size.
4. Legal-fiscal due diligence
Coordination with notary and attorney:
- Clean title confirmed by notary
- Solidarity Tax current if applicable
- Transfer tax correctly calculated
- Stamps and notarial fees projected
- Purchase structure: personal name, corporation, LLC, or trust, each with different tax implications
- Judicial action risk against seller (basic investigation)
Cost: notarial fees + legal advice $800-$3,000.
5. Use / neighborhood due diligence
- Consult neighbors about property and its history
- Visit at different times (morning, afternoon, evening, weekend)
- Investigate area security (cameras, guard, incidents)
- Nearby services (supermarkets, schools, hospitals)
- Future canton projects that may impact (roads, nearby construction)
- Noises and smells not detectable in single visit
Pre-purchase summary checklist
- Updated ownership certification
- Complete registry study
- Current cadastral plan
- Municipal tax current
- Solidarity Tax current (if applicable)
- Construction permits for buildings
- Professional CFIA appraisal
- Structural inspection (if applicable)
- Real measurement
- Verification of operational public services
- Consultation with neighbors
- Visits at different times
- Notarial and legal advice

Red flags detecting common scams
- Seller can’t show ownership certification in their name
- Seller’s excessive rush to close
- Price significantly below market without justification
- “In process” documentation or that “arrives next week”
- Impossibility to physically inspect
- International sale without valid CR power of attorney
- Expired or unapproved cadastral plan
- Multiple recent transfers in few months
- Liens that “clear with payment”
- Request for full payment before deed
Total due diligence budget
For standard $150,000 residential property:
| Concept | Cost |
|---|---|
| Records and certifications | $50-$100 |
| Professional CFIA appraisal | From approx. ₡150,000 (USD 300), per quote |
| Structural inspection | $300-$500 |
| Legal advice + notary | $1,500-$3,000 |
| Total DD | $1,850-$3,600 plus the appraisal |
Excluding the appraisal, this represents 1.2-2.4% of purchase price. Reasonable cost to protect a $150K investment.
FAQ
Should seller cover part of due diligence? Traditionally buyer assumes due diligence. Seller covers transfer tax (50% in some cases) and release of prior liens.
How long does complete DD take? 2-4 weeks for standard properties. 4-8 weeks for complex (commercial, large farms).
Can I do simplified DD to buy cheap? You can, but assume greater risk. Irreducible minimum: ownership certification + appraisal + notarial advice.
Does bank appraisal replace complete due diligence? No. Bank verifies only what’s needed for its guarantee. Due diligence protects buyer from all types of risk.
Conclusion
Professional due diligence in Costa Rica is an investment of roughly 1.2-2.4% of the purchase value, plus the appraisal, that can prevent much larger losses. Each component (registry, municipal, physical, legal, neighborhood) provides signals that together define if buying is worthwhile.
