Khorna Score · proprietary 100-point ranking
Last refreshed · May 2026 · methodology
vs portfolio · top tier
Six components, weighted by what drives outcomes.
Yield + appreciation are 50% of the score (weighted to what foreign investors actually underwrite). The remaining 50% is liquidity, demand, walkability, and developer quality · the data that distinguishes a good unit from a great one. Same methodology across the entire portfolio · A+ means the same thing in Mandarin Oriental Residences as in Tela Thonglor. Read the full methodology →

Same methodology, every unit
We don't tilt scores to favour units we want to sell. The formula is public · weights are public · raw data is auditable on /how-we-score.
Conflict policy
Higher-commission projects don't score higher. We surface conflicts in the underwriting deck if relevant. Score is not influenced by our payout.

FX rate: 1 THB = 0.0307 THB · refreshed 2026-04-30. Tax assumes 10% effective for Thai-domiciled foreign rental income · treaty crediting against home-country tax often reduces this further.

Bangkok prime delivers 2.4x the net yield of Singapore / Paris / London prime and at roughly a fifth of the entry price. The yield gap is structural · Bangkok is still being priced as a yesterday-Asia city, not the safe-haven capital it has become. See our analysis.
