Don Diego purchase guide
A practical path for understanding buyer profiles, documentation, and next steps at Don Diego. The final judgment always belongs to your notary and advisers according to your case.

Key stages in the Don Diego purchase process
Your transaction at Don Diego is tied to a specific product in the master plan: typology, delivery status, location within the community, and use of common areas and amenities, all reflected in the sales pack and, later, in your agreements. The counterparty is the developer or a party you verify as authorized; your counsel will align what is offered in marketing with the governing contracts and the documentation supporting the sale at this project.
Don Diego may set initial terms and, if applicable, a reservation. Any payment for a hold should be governed in writing: refunds, time limits, and the path to a promesa or definitive private contract. You should not transfer funds before your attorney has reviewed the terms in the context of this development.
Before full execution, you may see letters of intent or similar drafts. They can frame price, currency, and schedule, and sometimes conditions or exclusivity. Your counsel must confirm whether they create binding obligations, conditions precedent, or firm deadlines, so the language stays consistent with what you later sign with the Don Diego team.
This is where price, payment schedule, delivery obligations, penalties, and termination rights are set out. For construction or presale, construction milestones and “delivery standard” need to be explicit. The signed agreement, not side conversations, governs the commercial relationship for your home at Don Diego.
Your team will review title, encumbrances, tax certificates, and the master-development and HOA-style rules that apply to your unit, using information from the developer and independent searches as appropriate. If you are buying while work is in progress, permits, security instruments, and delivery criteria for your home in the development are part of that file.
Transfer or the agreed structure is usually formalized in a public deed. The notary will carry out the fiscal and formal steps and collect applicable taxes and fees. Ask for a line-by-line statement well before signing and align it with what Don Diego and your private counsel told you to expect.
After the deed, the record that protects your interest should be put in place in the public registry, and you should receive the evidence you need. If a fideicomiso, company, or other vehicle is used, your adviser explains how you evidence and exercise your rights in practice for the home you are acquiring in the project.
After closing, you will complete service transfers as far as the law and vendors allow, register with the administration and rules that govern Don Diego as a large planned community, and take receipt of the home. Insurance should follow how you will actually use the property in San Miguel: primary home, second home, or—where permitted—rental.
Ongoing items may include property tax (predial) and, if a vehicle was used, corporate upkeep. A purchase in Guanajuato does not replace any reporting or tax duties you have elsewhere. Use the regional notes that follow to brief your non-Mexico advisers, based on the purchase you are completing at Don Diego.
How a purchase is structured at Don Diego (San Miguel de Allende)
At Don Diego, as in most substantial residential transactions in Mexico, closing is usually built around a public deed before a Mexican notary public: that office formalizes the instrument, calculates and collects many of the taxes and fees tied to the closing, and, where applicable, coordinates registration. It does not replace independent counsel for negotiating or reviewing the developer’s contract on your side.
Don Diego is located in San Miguel de Allende, Guanajuato—generally outside the coastal or border “restricted” band that often requires a fideicomiso. Title in your name or through an entity you control is often available depending on the specific lot or unit. Your notary and legal team confirm the structure for the property you are actually buying, not a generic “Mexico” rule of thumb.
In line with law and good AML practice, the project will require identification, proof of address, and a documented source of funds. Those steps are part of a development of this scale, not a checklist disconnected from the Don Diego process.
A quick peek “back home” (US, Canada, Europe & Latin America)
If you still pay taxes or hold bank accounts somewhere else, these topics come up a lot. They’re not a complete list—just a starting point to discuss with a qualified adviser where you file.
United States
Many U.S. filers want to know how Mexico fits with reporting and tax rules at home. The details are personal and the rules change—your CPA is the one to trust.
- Owning a home in Mexico can interact with U.S. reporting in ways that don’t show up the same as a U.S. house; forms like 8938 or other disclosures are sometimes in play. Don’t equate a deed with a bank account for reporting—get advice that matches your actual facts.
- If you open or control foreign bank or brokerage accounts, you may have FinCEN (FBAR) and other filings to think about separately from the property.
- Estate plans that work in the U.S. don’t always move neatly across a border. Ask whether wills, trusts, and beneficiaries need a coordinated update.
- If you rent the home out, both Mexican and U.S. tax ideas may apply to income, deductions, and (where relevant) treaty positions.
