How to Tell If a Developer Is Reliable: The Real Checklist

How to Tell If a Developer Is Reliable: The Real Checklist

Whether a developer is reliable doesn't depend on how many renderings they show or how many projects they announce. It depends on how many they delivered, on what timeline, and whether those properties are already registered in the buyer's name. That's the question that separates a real portfolio from a catalog of promises — and it's the one you'll be able to answer with the checklist below.

How do I verify their track record?

Verifying a developer's track record means tracking projects already delivered, not projects in progress or on paper. Ask for the complete list of previous developments — not just the two or three that appear in their sales materials — and for each one ask three things: promised delivery date, actual delivery date, and whether buyers already have their deed in hand.

A serious developer has no problem sharing this, because it's verifiable data: you can contact buyers from previous projects, check if there are public complaints or ongoing legal proceedings, and confirm in the Public Registry of Property whether the units from those projects have already changed ownership. If the developer dodges the question, changes the subject, or only offers curated testimonials, you already have information.

The comparison that really matters is between the promised timeline and the delivered timeline, project by project. An isolated delay can be explained by market or weather conditions. A pattern of delays across the entire portfolio is a mechanism, not an accident: it says how that company plans, finances, and prioritizes its projects — and that mechanism is going to repeat in the project they're selling you today.

For you, this changes the question you ask in the sales office: not "how many projects do they have?", but "how many did they deliver on the date they promised, with a deed, in recent years?".

What permits should they have?

A development must have the current permits and licenses authorizing construction and land use before they sell you a unit, and your job is to ask to see those documents, not just hear that they exist. Among what's normally required for a project are authorization of land use compatible with what's being built, a construction license issued by the corresponding municipal authority, and, when the project is in a coastal zone or with relevant environmental impact, an environmental impact statement before the federal authority in charge.

Don't assume a developer complies with this because they say so in a brochure or because the mechanism of transferring that responsibility is on the seller. Ask for the documents, with file number and validity date, and — if you have doubts about which exact procedure applies to the zone and type of project you're evaluating — confirm directly with the Quintana Roo municipal or state authority what permits are mandatory for that specific land use. The names of procedures and the agencies that issue them can vary by municipality, so don't take a generic list as good without checking it with the local authority.

The practical consequence: if the developer can't show you current permits with a verifiable file number, you're not buying an authorized project, you're buying a promise that it will be someday.

What protects my money?

What protects your money during the presale is the legal structure under which the project is managed — and there the guarantee escrow is a common figure in real estate developments, although its exact scope (what it covers and what it doesn't) varies depending on how it's set up in each particular project. Don't assume what's protected without reading the specific escrow contract for the unit you're buying.

What you can and should ask for is: the name of the escrow institution, the complete escrow contract (not a commercial summary), and a written explanation of what happens to your contributions if the project stalls or the developer fails to deliver. An independent legal advisor — not the developer's lawyer — should review that document before you sign.

Along with that, ask for the property registration history of previous projects from the same developer: how many units sold already have a definitive deed in the buyer's name, and how much time after physical delivery was that deed formalized. A developer can deliver keys on time and still take years to register — and until you have a deed, your right to the property rests on a contract, not a title.

To dive deeper into how the entire purchase process is structured, from reservation to signing, it's worth reviewing the buying guide, which explains the stages that precede this point.

What do I check on site?

What you check on site is whether the physical progress of the work matches the progress the developer reports in their sales materials — and the discrepancy between the two is one of the most reliable warning signs that exist. Visit the site in person, don't rely solely on photos or videos sent by the sales team, and compare what you see against the schedule presented to you at the time of signing.

On paper, ask for the escrow or legal vehicle account statement managing the project's resources, progress reports signed by the supervisor or contractor, and any modifications to the original permits — a change in land use or unauthorized expansion during construction is a serious alert. If the developer doesn't have these documents organized and accessible, or delivers them reluctantly, it's a repeating pattern: the same opacity you see before buying is what you'll face after, when you need to solve a problem.

The consequence is simple: if physical progress lags months behind what the sales materials say, and the developer doesn't acknowledge it openly, you won't have a way to anticipate a delay until it's too late to reschedule your own move or financial closing.

What warning signs should concern me?

The clearest red flags are pressure to close quickly, opacity in documentation, and prices that don't fit the market logic in that area. None of these alone is definitive proof of a problem, but when they appear together, the pattern matters more than any isolated signal.

Closing pressure — discounts that "only apply if you sign today", inventory that "is running out" without showing you actual sales progress — pushes you to decide fast instead of decide well. A reliable developer can stand behind a reasonable offer without artificial urgency, because their business doesn't depend on you not comparing.

Documentary opacity is the second signal: if it's hard for you to get the complete escrow contract, permits with file numbers, or the property registration history from previous projects — and instead they offer summaries, video testimonials, or verbal promises — the problem isn't that they don't have the information, it's that they don't want you to review it carefully.

And prices out of market, both suspiciously low or suspiciously high without location or specification justification, deserve the same question: why? A low price might mean the project needs urgent cash flow — which says something about its financial health — and a high one without apparent reason might be charging a brand premium that the actual track record doesn't yet support.

This isn't suitable for someone looking to decide in a single visit: evaluating a developer with this level of detail takes time, asking for documents, and sometimes waiting for answers. If your decision timeline doesn't allow for that process, the risk you assume grows in direct proportion to how short your review is.

Frequently Asked Questions

What is a guarantee escrow and why does it matter? It's a legal figure used in some developments to manage buyer resources during presale, but its specific scope — what it protects and what it doesn't — depends on how it's set up in each project. It matters because you can't assume generic protection: you have to read the particular contract and, if in doubt, consult it with an independent real estate lawyer before signing.

How long does it take to evaluate a developer before buying? There's no fixed timeline, because it depends on how accessible the documentation is and how quickly they respond to your requests for permits, contracts, and property registration history. What you can anticipate is that a serious verification process takes more than a single visit or phone call — and if the developer pushes you to decide before completing it, that itself is a signal to consider.

Can I trust testimonials from other buyers that the developer shows me? Testimonials that the developer themselves selects and presents have an obvious bias: nobody showcases the unsatisfied buyer. It's more useful to independently seek out buyers from previous projects from the same developer, without going through the sales team filter, and ask them directly about delivery timelines and property registration process.
