Khorna Verdict reasoning · refreshed monthly
Khorna Score A (78/100). DDproperty median asking is 18% 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.

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.

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.

Assignment / private resale before construction completes
Most Bangkok developers permit contract assignment before handover (with admin fee 1-2%). Bangkok prime in this corridor compounds at 8.5% per year. The math below shows what assigning the contract early looks like · gross gain net of assignment fee + SBT (3.3% if held under 5 years).

Sansiri / AP / Origin permit free contract assignment. Noble / Ananda apply admin fees (assumed 1.5% in this model). A handful restrict resale until specific construction milestones · we flag this in the Khorna Verdict reasoning where applicable. SBT applies if you assign before 5 years from contract date · we model this in.
How the phased pricing ladder works
This is not an accident. The phased release is a deliberate revenue strategy: the developer wants the project to be visibly “moving” in marketing materials (which sells faster) AND wants to capture the upside of phase-by-phase price increases (which compounds the project total revenue). Both goals align with the buyer-of-the-month pattern · early phase buyers get below-comp pricing, late phase buyers pay the full marketed price.
Phase 1 · Private viewing
Lowest pricing, best foreign-quota allocation, full SPA negotiation room. Closed sales · invitation-only or developer-direct. This is where Khorna's sourcing pipeline operates.
Phase 2-3 · Soft launch
3 to 7% uplift per phase from phase 1. Public marketing begins. Still some negotiation room · foreign quota half-filled. By the time English-language portals translate the project page, soft launch is usually closing.
Phase 4-6 · Hard launch
15 to 25% uplift cumulative from phase 1. Full marketing campaign. Foreign quota mostly committed. SPA take-it-or-leave-it. This is where most retail foreign buyers enter · paying the full ramped price for what's left of the foreign quota.
The strategic implication for an investor · being in phase 1 means buying at 80-85% of the price the same unit will list at by phase 4. You can hold to handover and capture the construction-period appreciation, OR assign the contract during phase 4-6 marketing peak when the pricing ladder is at its highest. Either way, phase-1 access is the alpha.
Why speed matters · the best units go first
Foreign-quota inventory is allocated unit-by-unit, not by category. The corner units, the high-floor units, the units with unobstructed views, the units with the best floor plans · all get reserved by the buyers who arrive first. By the time public marketing scales, the foreign-quota allocation that's left is the bottom-third of the building.
This isn't aggressive sales tactic · it's how the developer's allocation system works. The corner-line foreign-quota cap is typically 1-2 units per floor; if those go in phase 1, phase 4 buyers can't access them at any price. We track which specific unit numbers are still available in foreign quota for every project · the difference between “there's a 2-bed available” and “there's a 2-bed corner unit on floor 28 still in foreign quota” is what we work in.
