The Key Rama 3

Gross rental yield at The Key Rama 3 is 4.97%, computed as (12 × median monthly rent) ÷ median sale price across our active listings. Versus the current Thai MRR of 7.10%, that is a -2.13pp spread. This is a pre-tax, pre-vacancy figure — net yield is typically 1.5–3pp lower.

The Key Rama 3 has a RealData Bubble Index of 106 — that is 6% above the median price-per-sqm of the Bang Kho Laem district, which we classify as at-market.

The Key Rama 3 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.

Latest WAQI air quality reading near The Key Rama 3 is 53 — 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).

The Key Rama 3 has a RealData Resale Liquidity Score of 66/100 — liquid — resale demand is healthy. 25% 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.

The Key Rama 3 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.

The Key Rama 3 scores 45/100 on RealData's Retiree Suitability Score — a fair fit for a retirement-visa buyer. There is 1 hospital/clinic within 1km, and the latest air quality reads 53 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.

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.
