Due Diligence Checklist: Buying Property in Mexico

Most real estate mistakes in Mexico happen not because the laws are complex, but because buyers skipped verification steps that would have caught the problem before signing. This checklist gives you a systematic framework for due diligence on a Mexico property purchase, with the specific items your notary and attorney should be checking — and what you should verify independently.

---

Phase 1: Title and Legal Status

These are the most critical checks. A property with title problems is not worth buying at any price until the problems are resolved.

Title Verification (Notary Performs)

• Current registration: Property is registered at the Registro Público de la Propiedad in the seller’s name
• Chain of title: Ownership history reviewed going back 10–20 years (notary looks for gaps, irregular transfers, inheritance issues)
• Certificate of no liens (certificado de libertad de gravamen): Confirms no mortgages, liens, or encumbrances
• Seller identification: Seller’s legal name matches the registration exactly (important for inheritance situations where name changes occurred)
• Power of attorney verification: If someone is selling on behalf of the owner, verify the POA is current, notarized, and properly executed
• Trust verification (fideicomiso): If property is held in a bank trust, verify the beneficiary is the seller and the trust is current

Legal Issues to Investigate

• Property not subject to expropriation proceedings
• No pending lawsuits (juicios) involving the property
• Ejidal status: Property is private land, not ejidal or communal land (check Registro Agrario Nacional for any property with rural or semi-rural adjacency)
• ZOFEMAT/coastal federal zone: For coastal property, verify exact boundary of the federal maritime land zone and that the property is not within it
• HOA/condo fees current: Request constancia de no adeudo from the development
• Predial (property tax) current: Request constancia de no adeudo from the municipal treasury (tesorería municipal)
• Water bill current

Phase 2: Permits and Zoning

• Building permit (licencia de construcción): Original construction permit exists for the structures on the property. Missing permits are common in older properties and must be regularized before sale (or negotiated)
• Completion certificate (constancia de terminación de obra): Confirms construction was inspected and approved
• Zoning compliance: Property use matches current zoning (residential, commercial, mixed). Especially important if you plan to operate a business or STR from the property
• Pool permit: If there’s a pool, verify it was permitted (many aren’t — this is usually fixable but adds cost)
• Extensions and additions: Any structure added after original construction should have a permit. Unpermitted additions are common and affect insurable value

Phase 3: Property Condition (Buyer Performs)

Your notary doesn’t inspect the physical property — that’s your job.

Structure

• Roof condition: Look for water damage, missing tiles, stains on interior ceilings (especially important in Mérida where summer rains are heavy)
• Foundation: Signs of settling — diagonal cracks in walls, doors/windows that don’t close properly
• Walls: Cracks (structural vs. cosmetic), moisture damage, salt efflorescence (indicates chronic moisture)
• Plumbing: Test all faucets, showers, toilets. Check water pressure. Ask about pipe material (PVC is fine; galvanized steel corrodes in Mexico’s climate)
• Electrical: Panel condition, whether wiring has been updated, ground fault protection
• Drainage: In Mérida, flooding in low-lying areas is a real concern during summer rains. Ask neighbors if the street floods

Systems

• Air conditioning: Test every unit. In Mérida, A/C is non-negotiable — verify age and condition. Budget $15,000–$30,000 MXN per unit for replacement
• Water cistern (aljibe): Mérida has periodic water pressure issues — most homes have a cistern. Verify it’s functional and clean
• Water heater: Age and condition
• Gas system: If the property uses gas (LP or natural gas), verify condition of tanks and lines

Exterior

• Roof drainage: Clogged drains can cause catastrophic damage in a single heavy rain
• Trees: Large trees near the structure (especially near Mérida’s colonial or older properties) may have roots affecting the foundation
• Boundary walls: Verify condition and that walls match property boundaries

Phase 4: Financial Verification

• Price is within market range: Research comparable sales in the area. Significantly below market is a red flag, not a deal — it often signals a title problem or an owner in distress (which can mean complications)
• ISAI and closing cost estimate: Get a written estimate from the notary before committing so you know the full out-of-pocket cost
• HOA fee verification: Get the current monthly fee in writing from the association, not just from the developer or agent
• Utility costs: Ask the seller for 12 months of CFE (electricity) bills. Mérida electricity bills are climate-dependent and can surprise buyers

---

Phase 5: Pre-Sale (New Construction) Specific Checks

If buying a pre-sale property, additional checks apply:

• Developer registration: Verify the developer is registered with PROFECO (consumer protection) and has a valid contrato de adhesión (standard contract template approved by PROFECO for new development sales)
• Trust or escrow for deposits: In Mexico, it’s best practice for deposits on pre-sale units to be held in a trust (fideicomiso) or escrow account, not in the developer’s operating account. Ask explicitly
• Developer track record: Research completed projects. Visit a completed development by the same developer — talk to residents if possible
• Delivery guarantee: What happens if the developer delays or doesn’t deliver? The contract should specify penalties
• Permit status at sale: At minimum, the developer should have the licencia de construcción approved before taking your deposit
• Title to the land: Verify the developer has clean title to the land where they’re building

Red Flags That Should Stop a Transaction

Never proceed without resolution on:

• Title not registered in seller’s name (or recently transferred for suspicious reasons)
• Liens or mortgages the seller claims are “about to be released”
• Unpermitted construction that the seller says “is easy to regularize” (get it in writing before signing)
• Seller or agent who resists your right to use an independent attorney or different notary
• Title that has passed through multiple hands in a short time at rising prices (possible fraud chain)
• Property adjacent to or overlapping federal maritime zone or ejidal land with unclear legal status
• Seller who needs you to sign “now” or the deal is gone — urgency pressure in real estate is almost always a manipulation tactic

This checklist covers typical due diligence for residential real estate in Mérida and Yucatán. Different property types (commercial, coastal, rural, pre-sale) require additional specific checks. Always work with a licensed notary and, for significant purchases, an independent real estate attorney.
