This is the operational checklist — not a discussion of why due diligence matters, but the 15 specific verifications to complete before signing on Mexican property as a foreign buyer in 2026. Each item below specifies what to demand from the seller, where to verify independently, and what failure looks like. Designed to be printed and worked through systematically.
Work this list in order. If any item fails, pause until resolved or walk away. Compressing due diligence to "save time" is the single highest-correlated factor in foreign-buyer post-purchase problems.
Phase 1 — Title & legal status (Days 1-7)
1. Current escritura pública verified at Registro Público
Demand from seller: Copy of current escritura pública.
Verify independently: Your attorney pulls a current Registry certificate confirming the seller is the registered owner.
Failure looks like: No escritura, only "private agreement"; or seller name doesn't match Registry name. → Walk away.
2. Title chain (antecedentes registrales) for past 20 years
Demand from seller: Authorization for attorney to pull chain.
Verify independently: Pull from Registro Público de la Propiedad. Each transfer must be properly recorded with no breaks.
Failure looks like: Gaps in chain, inheritances never properly registered, disputes recorded against title. → Resolve before signing or walk away.
3. Property is "propiedad privada regularizada" — NOT ejido
Demand from seller: Statement in writing.
Verify independently: Cross-check property location against state ejido boundary maps; if anywhere near ejido boundary, demand specific verification from Registro Agrario Nacional (RAN).
Failure looks like: Property is ejido land; "regularization in process" is presented as equivalent (it is not). → Walk away.
4. Lien and encumbrance certifications
Demand from seller: Current lien certifications.
Verify independently: Pull from Registro Público. Should show no mortgages, no liens, no easements adverse to use, no recorded disputes.
Failure looks like: Outstanding mortgage (must be paid at closing from proceeds); recorded lawsuit (must be resolved); easement that restricts use. → Address before closing.
5. Property tax (predial) — current and 5-year history
Demand from seller: Current predial paid receipts plus 5-year history.
Verify independently: Cross-check with municipal predial office.
Failure looks like: Unpaid periods; receipts for amounts inconsistent with assessed value. → Settle from purchase proceeds or deduct from price.
Phase 2 — Restricted zone & fideicomiso (Days 5-14)
6. Restricted zone determination — verified with GPS coordinates
Demand from seller: Property GPS coordinates and statement on restricted-zone status.
Verify independently: Cross-reference coordinates against official restricted zone boundaries (50 km from coast or 100 km from border, measured straight-line). For ambiguous cases, demand SRE pre-clearance.
Failure looks like: Seller says "outside restricted zone" but property is within 50 km of coastline measured properly. → Adjust to fideicomiso structure (don't proceed without).
7. Fideicomiso bank selection & pre-approval (if restricted zone)
Demand from seller: Whether existing fideicomiso transfers or new is required.
Verify independently: Identify fideicomiso bank (BBVA, Santander, Scotiabank, HSBC are common). Get setup cost, annual fees, and required documents in writing. Initiate setup process — takes 4-10 weeks.
Failure looks like: Bank refuses for reasons related to property (e.g., property is too rural, has title irregularities). → Investigate why.
8. SRE permit application (if restricted zone)
Demand from seller: Property details for permit.
Verify independently: Submit to Secretaría de Relaciones Exteriores. Approval typically 3-6 weeks.
Failure looks like: SRE rejection for property-specific reasons. → Don't close until resolved.
Phase 3 — Physical & structural (Days 7-14)
9. Independent appraisal by your-chosen valuador
Demand from seller: Property access for appraisal.
Verify independently: Engage qualified valuador you choose (not seller's). Cost: $400-$1,000 USD typical. Cross-check against 3-5 verifiable comparable sales in past 12 months.
Failure looks like: Appraisal >10% below asking price; or no truly comparable sales exist (thin market). → Renegotiate or reconsider.
10. Boundary verification & plano topográfico
Demand from seller: Current plano topográfico (survey).
Verify independently: Physically walk boundaries with surveyor. Verify against escritura description and neighboring properties. For larger lots, current survey may be needed ($500-$2,000 USD).
Failure looks like: Physical occupation exceeds escritura boundaries (encroachment) or neighbors dispute boundary. → Resolve before signing.
11. Structural condition & mechanical systems
Demand from seller: Property access for inspector.
Verify independently: Mexican home inspection is less standardized than US — but qualified inspectors exist in major cities ($300-$800 USD). At minimum verify: structural integrity, roof condition, electrical compliance, plumbing condition, foundation, HVAC.
Failure looks like: Major deferred maintenance, structural issues, code violations. → Use as negotiation lever or walk away.
Phase 4 — Utilities & service infrastructure (Days 10-18)
12. Water access verified with utility
Demand from seller: Current water bill, water permit status.
Verify independently: Confirm with municipal water utility (OOMSAPAS / SIMAPAS / SEDAPAL depending on city). For new construction or major remodel, verify water concession can be obtained. Critical in BCS, parts of Yucatán, and any rural area.
Failure looks like: Property has no formal water permit; uses neighbor's well; or water concession denied for proposed use. → Address before signing.
13. Electricity, gas, internet certifications
Demand from seller: Current utility bills.
Verify independently: Confirm CFE service is current (no outstanding electrical bill transfers to new owner). Verify gas connection legal status. Verify fiber/cable internet availability if important to you.
Failure looks like: Outstanding CFE debt of $1,000+; gas connection not legally registered. → Settle from purchase or address.
Phase 5 — Condo / HOA specific (Days 10-18)
14. Condo régimen documents and HOA financial health
Demand from seller: Régimen de condominio document; current and 3-year history of HOA financials; current and 3-year history of asamblea minutes; list of pending special assessments.
Verify independently: Read the documents. Confirm HOA maintenance reserve ≥ 6 months operating expenses. Confirm no pending lawsuits affecting building. Confirm no special assessments in past 24 months or pending.
Failure looks like: Empty reserves; recent or pending special assessments >$5K USD; ongoing lawsuits about building. → Walk away (very high-risk).
Phase 6 — Closing & final verification (Days 14-21)
15. Notario pre-closing verification
Demand from seller: Agreed notario selection (you choose, not seller).
Verify independently: Within 24 hours of closing, notario performs Registry pre-search confirming no other party has registered a prior transfer of this property. Notario reviews all certifications, payments, identities. Title insurance (Stewart Title or First American, $1,500-$5,000 USD) recommended for properties over $300K USD.
Failure looks like: Notario can't verify cleanly; another party has registered something; new lien appears. → Don't close.

Total time and cost — for budgeting
- Time: 21-45 days from full engagement to clean-to-close.
- Total due diligence cost: $3,000-$8,000 USD for $300K-$1M property; scale upward proportionally.
- Compared to typical loss when due diligence is skipped: $15,000-$500,000 USD per the patterns documented in our common mistakes and scams to avoid guides.
What to do with this checklist
Print it. Work through it sequentially. Note dates of each verification completion. Keep all certifications and receipts in a single folder (physical or digital) for the entire ownership period — they prove your due diligence if any future dispute arises.
If you're working with a Mexican attorney (recommended for any transaction above $100K USD), give them this checklist. A competent attorney will already perform these verifications; the checklist documents that they did. An attorney who finds the checklist unfamiliar is the wrong attorney.
FAQ
How long does proper due diligence on Mexican property take?
For a clean transaction with a cooperative seller: 14-21 days from request to all verifications complete. For a property with complications (older title chain, condo with disputes, restricted zone): 30-45 days. Foreign buyers who try to compress due diligence into 5-7 days are the population most likely to encounter post-purchase problems.
What's the single most important document to verify?
The current escritura pública with prior registration entries (antecedentes registrales) from the Registro Público de la Propiedad of the state. This confirms the property is private property (not ejido), that the seller is the registered owner, and that the title chain is intact. Without this, no other verification matters.
Do I need a Mexican attorney even if the notario is doing the closing?
Yes, for any foreign buyer in any transaction above ~$100K USD. The notario is technically a public officer for both parties and the state — but in practice, the notario is closest to the seller (who chose them or whose broker typically chose them). Your independent attorney represents only you, catches what the notario might miss, and provides written opinion on title, contract terms, and risk factors.
What predial certifications do I actually need?
Current paid predial certificate (showing all property tax paid through current quarter) plus historical predial certifications going back 5 years (showing no gaps or unpaid periods). Any unpaid predial transfers to the new owner at closing — so it must either be settled by seller or deducted from purchase price.
What's the cost of complete due diligence on a typical foreign-buyer transaction?
$3,000-$8,000 USD for a property in $300K-$1M USD range. Breakdown: Independent attorney $2,000-$5,000; independent appraisal $400-$1,000; title insurance optional $1,500-$5,000; gestoría for permits/certifications $500-$1,500. For properties above $1M, scale costs upward proportionally.
