Khorna Verdict reasoning · refreshed monthly
Khorna Score A+ (81/100). DDproperty median asking is 28% above our access price · this is a rare situation (typically off-market, distressed, or pre-launch quota). We commit to negotiating within 5% of our seed price · or we adjust the verdict.

vs portfolio · top tier
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.

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.
