Short answer: Casas en Valladolid limits the personal and property information used during an inquiry or transaction, shares sensitive material only for a defined purpose, and avoids publishing an occupied property's exact location without a reason and authorization. These are operating practices under Mexico's current private-sector data law, not a promise that digital communication has zero risk.

What information a real estate inquiry may involve
A buyer, renter, seller or landlord may provide a name, phone number, email, budget, identity documents, title documents, tax information, property address or financial evidence. Not every inquiry needs every item.
We start with the minimum useful context. Identity, title and financial documents should be requested only when the transaction stage and verification purpose justify them.
Three practical protections
1. We limit early collection
A first WhatsApp conversation normally needs a name, goal, preferred area and practical budget. It should not require a full passport, deed or bank statement. More sensitive documents belong later in a defined verification process.
2. We control property-location exposure
Public listings can describe an area without exposing every detail of an occupied home. Exact access information, seller contact details and security-sensitive facts should be shared with appropriate context rather than posted indiscriminately.
3. We separate coordination from professional review
An advisor may coordinate documents with the seller, buyer and notary, but each recipient should receive information for a legitimate task. A notary, lawyer, appraiser or technical professional may need different material. “Everyone in the transaction” is not a valid reason to forward every file to everyone.
What Mexico's current privacy law requires
The official Federal Law on Protection of Personal Data Held by Private Parties is the primary legal source.
- Articles 14 to 16 address the privacy notice and the information it must contain.
- Article 18 requires administrative, technical and physical security measures.
- Article 19 addresses notice of a significant security breach.
- Article 20 requires confidentiality to continue after the relationship ends.
- Articles 21 to 24 provide access, rectification, cancellation and opposition rights, commonly called ARCO rights.
The law does not make email, messaging or cloud storage automatically safe. It requires purposeful handling, appropriate safeguards and a route for data-subject rights.
Safer ways to send documents
- Confirm who requested the document and why.
- Redact unrelated account numbers, signatures or identifiers when a full copy is unnecessary.
- Do not send sensitive files to a number or address copied from an unverified message.
- Ask whether the notary prefers a specific channel or format.
- Keep an original offline or in a controlled account.
- Report a mistaken recipient immediately rather than hoping the message is ignored.
How to make a privacy request
Identify the name and contact details used in the inquiry, describe the information or correction requested, and provide enough context to locate the record. Do not send additional sensitive documents until the recipient and request path are confirmed.
Contact Casas by WhatsApp about a privacy or transaction-data question and ask for the appropriate follow-up channel.
Verify the people handling a transaction
Privacy is only one part of trust. Verify the legal identity and role of each advisor, seller representative and professional. Yucatán's public INSEJUPY registry lists licensed real estate advisors. Casas en Valladolid publishes its proof through Dalila Yesenia de León Bañuelos, Type A, Folio A-00030.

FAQ
What are ARCO rights?
They are rights to access, rectify, cancel or oppose certain processing of personal data under the applicable law and procedure.
Should I send my passport in the first WhatsApp message?
Usually no. Start with the non-sensitive facts needed for the inquiry. Confirm the recipient, purpose and stage before sharing identity documents.
Why might an exact property location be withheld?
An occupied property's address can create privacy and security risks. Qualified viewers can receive appropriate access details after basic coordination.
Does Casas share documents with a notary?
When a transaction requires it and the parties have identified the notary and purpose, relevant documents may be coordinated. Not every document is relevant to every participant.
Is WhatsApp completely private?
No communication channel removes all risk. Verify the recipient, limit content and use the channel appropriate to the sensitivity of the document.
Can I ask to correct my contact information?
Yes. Provide enough context to identify the record and clearly state the correction requested.
Does deleting a chat delete every transaction record?
Not necessarily. Legal, contractual or operational retention duties may apply. A privacy request should be evaluated against the applicable purpose and law.
Does an INSEJUPY license guarantee privacy compliance?
No. It verifies real estate licensing status, while privacy duties arise from separate law and operating practices. Both should be checked as part of trust.
