Brochures lie. Spreadsheets don’t.

The brochure quotes a gross number. The report models the net one — after vacancy, management, CAM and tax. Here is what the screen did to the market.

3,331 listings screened on one standard 100%
2,285 survived to be graded
147
rated Very Good or better 4.4%

Collected from 2,921 sale-side records and 5,503 rental records across six platforms.
Gross rent − 15% vacancy − 12% management − CAM − Land & Building tax.

1,151 of the 2,285 graded were marked Avoid. 43 rated Excellent.

The screen exists to throw work away.

This is the engine, not a metaphor. I ran 3,331 Chiang Mai listings through this screen and bought one that survived — a 2.15M THB freehold, deed in my name. Run entirely by me: no juniors, no outsourcing, no referral fees. See the math →

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.”

Anonymous
★★★★★

“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.”

Paco S.
★★★★★

“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.”
