// The free sample
These are two of the 89 rows, exactly as delivered. What is blocked out is what you are paying for.
// Row A
Ratchada / Rama 9
// Row B
On Nut / Bang Chak
Two buildings, two catchments. Between them, all twelve columns the file carries, without either row handing over the answer. In the file, all twelve are filled on all 89 buildings.
1 June 2026 pull
// What this is
Brochures and listing pages rank on what is easiest to show. None of them rank on what the unit nets.
The fix is boring. One standard on every building, then publish what survived it and what did not.

Built from 907 rent-validated units across 89 Bangkok buildings, cross-checked against 5,644 separate rental listings. A building enters the file at three or more validated units, then is cut again on rent confidence. Figures are the 1 June 2026 pull.
// Before you buy
13 buildings met the unit bar and were still dropped.
Nine had rent evidence from a single source. Four carried a rent flag. They are not in the file, because publishing them would mean publishing a number I cannot stand behind.
Two catchments are missing entirely.
Silom / Sathorn and Chatuchak / Lat Phrao produced no bucket that survived rent validation in this pull. They are not in the file. If those two areas are your search, this guide is not for you.
The dataset clips at ฿12,000,000.
This is not a luxury-tier product and does not pretend to be one. Nothing above that ceiling entered the pull.
It is a snapshot, not a feed.
Every figure is the 1 June 2026 pull. Listings turn over. The file tells you how these buildings priced and rented at that date, and makes no claim about any other date.
A yield is only as good as the rent under it, and a rent taken from one listing is an asking price, not evidence.
Rent here is a cross-source consensus. Asking rents are collected per platform, filtered, then combined per building. A building needs agreement from at least two independent sources to publish. Where two sources disagree by more than 15%, the lower figure is taken, not the average.
Single-source rows are excluded entirely. That is the difference between this file and a portal export: a portal shows you what one advertiser typed. This shows you what survived being checked against somebody else.
Every building carries its confidence tier in the file, so you can see which rows are multi-verified and which are mildly divergent. Nothing is presented as more certain than it is.
Is this a shortlist, or the whole file?
Both, and the file is the point. There is a ranking, but the ranking is only the conclusion. What you are paying for is the 89 buildings underneath it with every column filled, so you can sort it yourself and disagree with me.
Do you sell property?
No. No commission, no introductions, no referral fees, no listings. I am paid for the analysis and nothing else, which is why a building can appear in this file with numbers that argue against buying it.
Can you confirm the foreign-quota slot for me?
No, and be careful with anyone who says they can from a desk. The file reports an observed marker — that foreign-quota availability was visible for that building at the time of the pull. Actual slot availability changes and must be confirmed with the building’s juristic office at the point of purchase. 88 of the 89 carry the marker.

// What buyers say — about the $20 Protocol, not this guide
“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.”

The Bangkok guide is new and has no reviews of its own yet. That one is for the Protocol, and it stays labelled that way until this file earns its own.
