We compute this from how much of this building's for-sale supply actually clears the market and how fast — tracking every listing from the day it appears to the day it disappears. A higher score means units here tend to find buyers; a low score warns that your exit could be slow. This is an availability signal, not a guarantee of sale price.
Retiree suitability
good place to retire?A retirement-focused read on the location: weighted toward nearby healthcare and clean air, then car-free transit and daily errands. Thailand's retirement (O-A/O-X) visa buyers weigh these very differently from young investors — this score reflects their priorities.

Air quality
5 months agoSource: WAQI station Bangkok. AQI is a 0–500 composite scale (US EPA). Values above 100 are unhealthy for sensitive groups; above 150 for everyone.
Ground stability
is the land sinking?Outer ring, largely stabilised since groundwater pumping was regulated. District-level estimate from published InSAR and groundwater-monitoring studies — a relative long-term signal, not a per-building survey. Land subsidence amplifies the same areas' monsoon-flood risk over a 10–20 year horizon.

Frequently asked questions
Is Ratanakosin Island overpriced compared to the rest of Bangkok Noi?▾
Ratanakosin Island has a RealData Bubble Index of 68 — that is 32% below the median price-per-sqm of the Bangkok Noi district, which we classify as underpriced.
What is the monsoon flood risk at Ratanakosin Island?▾
Ratanakosin Island sits in a district with a RealData Flood Risk Level of 3/5 — neighborhood-level common. Risk is district-level, drawn from Bangkok Metropolitan Administration Drainage Department records, JICA reports, and the 2011 great-flood inundation map. Individual buildings may still flood ground-level parking even in lower-risk districts.
How is the air quality at Ratanakosin Island?▾
Latest WAQI air quality reading near Ratanakosin Island is 41 — Good. This is the index value from the closest World Air Quality Index station; PM2.5 levels in Bangkok swing seasonally and can spike during burn season (Feb–April).
Is Ratanakosin Island easy to resell?▾
Ratanakosin Island has a RealData Resale Liquidity Score of 28/100 — slow — your exit could take a while. 0% of the for-sale supply we tracked here cleared the market. We compute this by tracking every listing from the day it appears to the day it leaves the market, so it reflects how much supply actually clears and how fast — not just the asking price. It is an availability signal, not a guarantee of sale price.
Is the ground sinking at Ratanakosin Island?▾
Ratanakosin Island sits in a district with a RealData Ground Stability (land-subsidence) level of 2/5 — low (largely stabilised). Bangkok rests on soft marine clay and sank as fast as ~120mm/year in the 1980s from groundwater over-extraction; regulation has since cut inner-city rates to near zero, but the eastern belt and coastal south keep sinking. This is a district-level estimate from published InSAR and groundwater-monitoring studies, and it compounds the same areas' monsoon-flood risk over a 10–20 year horizon — not a per-building survey.
Is Ratanakosin Island a good place to retire?▾
Ratanakosin Island scores 63/100 on RealData's Retiree Suitability Score — a good fit for a retirement-visa buyer. There is 1 hospital/clinic within 1km, and the latest air quality reads 41 AQI. The score weights nearby healthcare and clean air most heavily, then car-free transit access and daily errands — the priorities that matter to retirees rather than young investors.
How does RealData verify the numbers on this page?▾
Every figure is computed from live listing data we re-crawl across hipflat, dotproperty, ddproperty, and fazwaz (daily for Bangkok, weekly for the full Thailand sweep). District medians come from the same dataset, the mortgage benchmark is Bank of Thailand BTWS_STAT, and flood / livability layers are pinned to government and OpenStreetMap sources. We accept no payment from developers and no building can buy its way up a ranking — advertising on this page is sold by a third-party network that never sees the data.
