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 data is unavailable here, so the score uses the other factors only.

CAM × 12 (excl. tax)

CAM fee covers the building's shared maintenance (lobby, pool, cleaning). It directly reduces net rental yield — a high CAM relative to rent is a hidden killer. This building permits foreign-quota purchases. Confirm individual unit quota at the sales office before signing.

listings on FazWaz

Thai law caps foreign ownership at 49% per condominium. We count how many currently-listed units carry a "Foreign Quota" vs "Thai Quota" tag on FazWaz. High share = easy foreign entry; low share = act fast or consider leasehold. Sold quota is not visible — confirm individual unit eligibility at the sales office before signing.

Ground stability

is the land sinking?
L2/5
Low subsidence

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 Siamese Exclusive Sukhumvit 31 overpriced compared to the rest of Watthana?▾

Siamese Exclusive Sukhumvit 31 has a RealData Bubble Index of 121 — that is 21% above the median price-per-sqm of the Watthana district, which we classify as at-market.

Can foreigners buy a unit at Siamese Exclusive Sukhumvit 31?▾

Across the for-sale inventory we currently observe at Siamese Exclusive Sukhumvit 31, 25% of the units are flagged "Foreign Quota" — meaning legally eligible for a non-Thai buyer. A higher share = more foreign-eligible inventory still available. Thai law caps foreign ownership at 49% of a building's total floor area, so foreign-quota units sell out faster than Thai-quota units in popular buildings.

What is the monsoon flood risk at Siamese Exclusive Sukhumvit 31?▾

Siamese Exclusive Sukhumvit 31 sits in a district with a RealData Flood Risk Level of 2/5 — occasional puddling. 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.

Is the ground sinking at Siamese Exclusive Sukhumvit 31?▾

Siamese Exclusive Sukhumvit 31 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 Siamese Exclusive Sukhumvit 31 a good place to retire?▾

Siamese Exclusive Sukhumvit 31 scores 90/100 on RealData's Retiree Suitability Score — an excellent fit for a retirement-visa buyer. There are 17 hospital/clinics within 1km. 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.
