// Case Studies
Three real delivered $499 reports plus the one verified deed I bought myself. Every number is the actual research output — only the net yields and listing URLs are withheld.
// The report · Chiang Mai
11.2% gross on the entry leaders. The acquisition came from this scan — #3, Galae Thong Tower.
// The report · Phuket
Beach vs inland split. 13.74% gross on the leaders — the higher-current-yield leg of a Thailand portfolio.
// The report · Bangkok
52,000+ condos filtered. Thonglor/Ari CAGR play — the resale-liquidity leg, not the yield leg.

Stan Brinkman
Dutch, BBA Amsterdam. Built the engine. Underwrote his own deed.
“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.”
