GPTS BUILT TO KILL BAD DEALS, NOT TO SELL YOU A DREAM.

REGULAR CHATGPT IS A GENERAL BRAIN. GOOD AT TALKING. NEUTRAL AT EVERYTHING.

WHAT'S DIFFERENT FROM "NORMAL" CHATGPT?

NOT JUST CHATGPT. A TRAINED ENGINE.

CHATGPT IS A GENERAL BRAIN. IT ANSWERS BASED ON ITS TRAINING + WHAT YOU TYPE IN THE MOMENT.

FEUDO® GPTs ARE CUSTOM BRAINS:

WE LOCK IN THE RULES

How it should think like FEUDO®, what to question and what to ignore.

WE ANCHOR IT TO OUR OWN STACK

Documents, studies and real cases from the Mexican market.

WE LET IT USE THE WEB WHEN NEEDED

So it can pull fresh filtered context instead of guessing.

RESULT: IT DOESN'T "IMPROVISE A VIBE". IT APPLIES METHOD.

And the same engine you chat with here can also power other apps, sites or automations, doing the heavy thinking while you just see the decisions.

FEUDO® CAPITAL GROWTH ESTIMATOR GPT

Stress-test capital appreciation and equity growth before you fall in love with the listing.

WHAT IT DOES:

Helps you estimate realistic capital appreciation and equity growth for properties in Mexico, based on holding period, entry price, market patterns and risk. It’s built to kill “guaranteed capital gain” fantasies before you wire a single peso.

BEST FOR:

Comparing long-term capital growth between Tulum, Playa del Carmen, Cancun and CDMX.

Stress-testing “15–20% annual appreciation” claims from developers and brokers.

Estimating equity growth if you finance vs pay cash for a property in Mexico.

Understanding how presale pricing, delivery delays and market cycles impact your returns.

Checking if your capital is better in one property, two smaller ones, or parked in cash for now.

HOW TO USE:

Bring real numbers: price, currency, location, expected appreciation, holding period and any promise you were sold. The GPT will push back on aggressive assumptions and show you conservative, realistic and “walk away” scenarios.

TRY PROMPTS LIKE:

“Estimate realistic capital appreciation for a $250,000 USD presale condo in Tulum over 10 years vs buying a $220,000 USD resale condo in Playa del Carmen.”

“A developer in Cancun is promising 18% annual appreciation. Here are the details. Stress-test this claim and show me conservative scenarios.”

“Given these numbers [paste them], is it smarter to hold one condo in Tulum or two smaller units in Playa del Carmen for long-term capital growth?”

“Compare potential equity growth if I finance 70% of a property in Mexico vs buying cash, assuming different interest rates and exit timelines.”

“List the main risks that could kill appreciation for a Riviera Maya investment and how they affect my exit.”

FEUDO® PROPERTY FILTER GPT

Built to say “no” to 90% of listings in Mexico, so you can focus on the 10% that actually make sense.

WHAT IT DOES:

Helps you filter and rank properties in Mexico using FEUDO’s method: context first, numbers second, hype last. It looks at location, absorption, pricing, rental potential, developer risk and your real-life goals to decide what to discard fast.

BEST FOR:

Narrowing down a long list of listings from portals before talking to any agent.

Choosing between multiple presale and resale options in Tulum, Playa del Carmen or Cancun.

Filtering properties that don’t match your budget, risk tolerance, holding period or rental goals.

Spotting deals that look good on Instagram but are weak in real life.

Creating a short list of 3–5 properties that deserve deeper due diligence.

HOW TO USE:

Bring options, not ideas: links, prices, locations, sizes, fees, rental expectations and your plan (use, hold, flip, rent). The GPT will sort, rank and discard based on FEUDO’s filtering logic, not on who has the nicest render.

TRY PROMPTS LIKE:

“Here are 8 listings I’m considering in Tulum and Playa del Carmen. Filter them using FEUDO’s criteria and tell me which 2–3 deserve more analysis.”

“Compare this $180,000 USD studio in Tulum vs a $210,000 USD 1BR in Playa del Carmen for vacation rental income in the next 5 years.”

“Given my budget of $250,000 USD and plan to hold 10+ years, rank these properties in Riviera Maya from strongest to weakest.”

“Filter these options with the goal of using the property 2 months a year and renting it the rest of the time.”

“Tell me which of these listings I should discard immediately and why, based on location, pricing and red flags.”

FEUDO® LEGAL BRIEFING GPT

Read your contracts like an investor with criteria, not like a tourist signing a reservation form.

WHAT IT DOES:

Helps you review contracts, presale agreements and legal documents related to real estate in Mexico. It flags unclear clauses, risky terms and missing protections, without pretending to replace a licensed attorney.

BEST FOR:

Scanning presale contracts in Mexico for red flags before sending them to your lawyer.

Understanding what your rights and obligations look like across different payment schemes.

Flagging vague delivery timelines, penalty clauses and “force majeure” language in Riviera Maya projects.

Comparing two contracts for the same project or developer to see what changed.

Preparing better questions for your Mexican real estate attorney.

HOW TO USE:

Paste the contract or key sections. Add context: type of property, location, payment plan and what the developer or broker promised you. The GPT’s role is to highlight risks, vague language and blind spots you should clarify with a lawyer.

TRY PROMPTS LIKE:

“Here is my presale contract for a condo in Tulum. Highlight clauses that are risky or unclear for me as a foreign buyer.”

“Compare these two versions of a reservation agreement for a property in Playa del Carmen and tell me what changed in favor of the developer.”

“This contract has no clear delivery date. Explain why that’s a problem and what I should ask the developer to add.”

“Review this financing annex for a property in Mexico and flag any clauses that could allow the developer to change price or terms.”

“Give me 15 questions I should ask my lawyer about this Riviera Maya presale contract before I sign.”

FEUDO® VACATION RENTAL STRATEGY GPT

Turn “this looks good on Airbnb” into a real strategy with numbers, seasonality and risk baked in.

WHAT IT DOES:

Helps you build and stress-test a vacation rental strategy for properties in Mexico: pricing, occupancy, seasonality, costs, management and realistic net income. It’s here to challenge your “high season forever” assumptions.

BEST FOR:

Designing a vacation rental strategy for a new property in Tulum, Playa del Carmen or Cancun.

Estimating realistic occupancy and nightly rates for Riviera Maya based on your target guest and seasonality.

Understanding the impact of management fees, cleaning, capex and platforms on your net income.

Comparing buying a unit optimized for vacation rental vs long-term rental in Mexico.

Testing “guaranteed rental income” offers against realistic scenarios.

HOW TO USE:

Share your property details, location, expected nightly rate, occupancy assumptions, costs and who is managing it (you vs a company). The GPT will stress-test your expectations and help you build conservative, base and optimistic scenarios.

TRY PROMPTS LIKE:

“Help me design a vacation rental strategy for a 2BR condo in Tulum with a $230,000 USD purchase price and these monthly costs [paste list].”

“Given this location in Playa del Carmen and these sample Airbnb listings, what is a realistic nightly rate and occupancy for year 1–3?”

“Compare the net income if I self-manage vs hire a property management company charging 25% in Riviera Maya.”

“Stress-test this ‘guaranteed rental income’ proposal for a condo in Cancun and show me the risk if occupancy drops.”

“Given my budget and risk profile, should I aim for vacation rental or long-term rental in this area of Mexico?”

FEUDO® GPT DISCLAIMER

These tools are here to help you think, not to replace work you still have to do in the real world.

THESE GPTS CANNOT:

FIND OR SELL PROPERTIES FOR YOU.

They don’t scrape portals, chase agents or source off-market deals.

ACT AS YOUR LAWYER, BROKER, ACCOUNTANT OR NOTARY.

They can brief you and flag risks, but they do not give formal legal, tax or investment advice.

GUARANTEE ROI, APPRECIATION, OCCUPANCY OR "ZERO RISK".

Any numbers they show are scenarios, not promises.

SEE THE PROPERTY IN REAL LIFE.

They can’t inspect construction quality, noise, neighbors or how far the beach “really” is.

ACCESS YOUR ACCOUNTS OR SIGN ANYTHING FOR YOU.

No contracts, no payments, no bank access, no talking to third parties on your behalf.

FIX BAD INFORMATION.

If you hide numbers, skip details or lie to yourself, the output will be just as wrong.

REPLACE DUE DILIGENCE

They can structure your questions and stress-test the deal, but you still need real professionals and your own judgment.

USE THESE GPTs AS A FILTER AND A BRIEFING ENGINE. NOT AS AN EXCUSE TO STOP THINKING OR TO OUTSOURCE RESPONSIBILITY.
