The Deliverable
What’s in the $20 PDF.
20 pages. Five steps. Every formula written out. No fluff, no upsell.
The 5-step underwriting checklist — pull the data, purge the unbuyable, apply the deduction matrix, layer the macro overlay, score the anomaly.
The 49% foreign quota math — how the building register works, what to check on the title, and the FET certificate sequence.
The freehold vs leasehold decision tree — tenure tradeoffs, depreciation math, and the question that determines which one fits your hold horizon.
The fee stack: gross → net — CAM, sinking fund, withholding, agent fee, vacancy. Every deduction worked out on a real Bangkok unit.
The Chiang Mai 2026 case study — the verified-deed close, with the math attached. Net yield in the canonical case study.
Building-by-building filter criteria — sinking fund liability, foreign-quota status, ownership-deletion rules, SPA clauses your lawyer should sign off on.
The Numbers
The Thailand Rental Yield Math.
The brochure quotes gross. The bank account pays net. The fee stack is where the gap lives.
The PDF works out each deduction on one Bangkok unit and one Chiang Mai unit, side by side. The verified-deed Chiang Mai number lives in the canonical case study.
The Legal Trap
Foreign Freehold, the 49% Math.
The Rule
49% of any condominium can hold foreign-name title.
Sold out the foreign quota? The unit isn’t legally yours under direct foreign title — even if the price is right. Step 02 of the protocol shows you how to verify quota status before the offer.
The Document
The FET (Foreign Exchange Transaction) certificate.
Wire from abroad, in foreign currency, with the FET document for any amount above the threshold. Skip this and you risk failing the title-transfer step at the Land Office. The PDF walks the sequence.
The Decision
Freehold vs Leasehold.
Freehold
Foreign name on the title (within the 49% quota).
- +Direct legal title to the unit.
- +No expiry on the ownership right.
- +Resale market includes Thai + foreign buyers.
- −Quota can be exhausted in popular buildings.
Leasehold
A long-dated lease, not ownership.
- +Available when freehold quota is full.
- −Expiry date depreciates the asset.
- −Resale market is narrower.
- −Renewal clauses vary contract-by-contract.
The Framework
The five-step protocol.
1,000+ in. About 30 survive the math. 1 closes.
STEP 01
Pull the data
Three source tiers including Thai-language seller groups. Derive building medians, not single asks.
STEP 02
Purge the unbuyable
Leasehold, nominee traps, sold-out foreign quotas, sinking-fund liabilities, off-plan risk.
STEP 03
Apply the deduction matrix
Five deductions against verified rent comps. About thirty units survive.
STEP 04
Layer the macro overlay
Transit, aviation signals, zoning. City intelligence for Bangkok, Phuket, Chiang Mai, Pattaya, Hua Hin.
STEP 05
Score the anomaly
Rank survivors by distance from the building median. Open at the median. Walk if the seller refuses to move.

This is for you if…
- +You treat the purchase like any other underwriting decision.
- +Math first, document review second, walkout number computed before you fly.

If I list a building, it is because the math worked. If I walk, it is because the math did not.
// Three questions you’re already asking
Read this before you click.
Is this AI-generated?
No. Every number, every formula came out of 18 months of fieldwork on 1,000+ listings. The deed-walkout video is the actual close. AI cannot stand in a Chiang Mai land office.
What if I’m not in Chiang Mai?
The framework is city-agnostic. Step 04 has specific intelligence for Bangkok, Phuket, Chiang Mai, Pattaya, and Hua Hin. The deduction matrix and offer scripts apply anywhere.
What makes you qualified?
Independent researcher, not a licensed advisor. No broker commission, no affiliate links, not paid by any developer or building. The PDF is the only thing I sell.
What buyers are saying
“Wasn’t expecting much for the price, but the yield breakdown is surprisingly dense. Worth it just for the data extraction framework alone. Straight to the point, no BS.”
“Exactly what I was looking to get started in buying a condo. I feel confident now that I’m not starting from scratch. Stan told me I could reach out to him if I ever got stuck — quite reassuring.”
“I used to spend a lot of time driving around Chiang Mai, scrolling real estate websites and visiting agents. This document convinced me to go further with Brinkman Data Analytics. It will save me a lot of time.”
Five stars on Gumroad. The framework they bought is the $20 PDF.

How do I get the file?
Click any "Get The Protocol" button. The Gumroad checkout opens in-page. Pay with card. The PDF is delivered to the receipt email immediately. No login, no list signup.
Why $20? It looks too cheap to be real.
Founders pricing while the catalog is small. The $499 Custom Report is the full underwrite on your city. The Protocol is the framework — same math, no shortlist.
First-time property buyer — is this for me?
Yes. The framework starts from the listing. If you can read a spreadsheet, you can run it.
Does this work outside Thailand?
The math is universal. Thailand-specific items (49% foreign quota, FET certificate, Chanote title) are flagged. See the framework →
What about a custom report for my specific shortlist?
The Custom Investment Report at $499 is 5-day deep-dive on your city + budget. See a sample →
Is this legal advice?
No. Brinkman Data Analytics is an independent research service. Nothing here is financial, investment, tax, or legal advice. Engage a licensed local professional before any closing.
