// What the screen rejected · Chiang Mai, March 2026
The brochure quotes gross. I model net. Here is what that did to one city.
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.
The screen exists to throw work away.
This is the engine, not a metaphor. I bought one that survived. Deed in my name. See the math →
