Bangkok Real-Estate Glossary

Plain-English definitions of every metric RealData publishes — and exactly how we calculate each one.

• Bubble Index

  RealData's Bubble Index scores a condo's asking price against the median price-per-sqm of its district: 100 is on par, above 100 is overpriced, below 100 is underpriced.

• Resale Liquidity Score

  RealData's Resale Liquidity Score (0–100) estimates how easily a unit in a building can be re-sold — higher means buyers are found faster and more of the supply clears.

• Retiree Suitability Score

  RealData's Retiree Suitability Score (0–100) rates how well a building's location suits a retiree, weighting nearby healthcare and clean air ahead of car-free transit and daily errands.

• Gross Rental Yield

  Gross rental yield is annual rental income as a percentage of purchase price, before costs — a quick gauge of income return on a Bangkok condo.

• Price per Square Metre

  Price per square metre normalises condo prices by unit size so buildings of different unit mixes can be compared like-for-like.

• Flood Risk Level (L1–L5)

  Flood Risk Level rates a location's flooding exposure on a five-step scale, L1 (lowest) to L5 (highest), based on Bangkok's district flood model.

• Developer Track Record

  A developer's track record is the scale and history of the projects they have built — a proxy for delivery experience and completion risk, especially on off-plan condos.

• Ground Stability (Land Subsidence, L1–L5)

  Ground Stability rates how much a location is sinking due to land subsidence, on a five-step scale from L1 (very low) to L5 (severe), because Bangkok sits on soft marine clay.

• Foreign Ownership Quota (49%)

  Thai law lets foreigners collectively own up to 49% of the total saleable floor area of any condominium; the other 51% must be Thai-owned.

• Freehold

  Freehold means owning a condo unit outright and indefinitely in your own name, registered at the Land Department.

• Leasehold

  Leasehold is a registered long-term lease of a property — up to 30 years per term — used by foreigners when freehold is unavailable or for land/villas.

• Livability Score

  The Livability Score summarises how convenient a building's location is — proximity to rail transit plus nearby hospitals, schools, and supermarkets.

• Super Value

  A Super Value badge flags a condo our model considers materially underpriced versus comparable buildings in its district.

• Days on Market (DOM)

  Days on Market is how long a listing has been advertised — a high DOM hints at overpricing or weak demand.

• MRR (Minimum Retail Rate)

  MRR is a benchmark lending rate published by Thai banks; it sets the baseline for most Thai mortgage pricing.

• Completion Year

  Completion Year is the year a condominium was finished and handed over — a proxy for building age, condition, and depreciation.
