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.

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.

Source: WAQI station National Housing Authority Dindaeng, Bangkok, Thailand (การเคหะชุมชนดินแดง). 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?
L1/5
Very low subsidence

Consolidated inner core with long-regulated groundwater — effectively flat today. 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.

Different portals can list the same condo at meaningfully different prices — agents pad listings, sellers pull old stock, prices drift. When portals disagree by more than ~10%, the lower number is usually the more recent / motivated seller.

Frequently asked questions

What is the gross rental yield at The Address Siam?▾

Gross rental yield at The Address Siam is 5.06%, computed as (12 × median monthly rent) ÷ median sale price across our active listings. Versus the current Thai MRR of 7.10%, that is a -2.04pp spread. This is a pre-tax, pre-vacancy figure — net yield is typically 1.5–3pp lower.

Is The Address Siam overpriced compared to the rest of Pathum Wan?▾

The Address Siam has a RealData Bubble Index of 185 — that is 85% above the median price-per-sqm of the Pathum Wan district, which we classify as bubble suspect.

What is the monsoon flood risk at The Address Siam?▾

The Address Siam sits in a district with a RealData Flood Risk Level of 1/5 — very low. 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 The Address Siam?▾

Latest WAQI air quality reading near The Address Siam is 55 — Moderate. 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 The Address Siam easy to resell?▾

The Address Siam has a RealData Resale Liquidity Score of 71/100 — liquid — resale demand is healthy. 34% of the for-sale supply we tracked here cleared the market. Listings that sold did so in about 0 days. 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 The Address Siam?▾

The Address Siam sits in a district with a RealData Ground Stability (land-subsidence) level of 1/5 — very low (consolidated inner core, effectively flat today). 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 The Address Siam a good place to retire?▾

The Address Siam scores 88/100 on RealData's Retiree Suitability Score — an excellent fit for a retirement-visa buyer. There are 9 hospital/clinics within 1km, and the latest air quality reads 55 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.
