How many condos under ฿20M in Koh Samui does RealData currently measure?

43 buildings match the filter, drawn from active sale and rent listings across hipflat, dotproperty, ddproperty, and fazwaz.

What is the median gross rental yield among these condos?

Median yield in this slice is 9.60%, a +2.50pp spread against the current Thai MRR of 7.10%.

What is the median sale price in this slice?

Median sale price is ฿10,750,000. Median monthly rent is ฿80,000. Both figures come from active listings on the four portals we track.

Why are some popular Koh Samui condos missing?

A building has to clear two bars to enter this ranking: (1) at least 2 active sale and 2 active rent listings on the same building, so the yield is not a fluke; (2) avg sale price ≥ ฿500,000 and yield ≤ 25%, which filters obvious price-parse outliers. Coverage widens with every weekly ingest cycle.

How do I shortlist one of these?

Each building name links to its full RealData report — yield, foreign-quota inventory, flood risk, days-on-market, cost-of-ownership panel. The bottom of this page has a free expert-opinion request that goes to one vetted independent broker who knows Koh Samui.

Gross yield = (12 × median monthly rent) ÷ median sale price. Pre-tax, pre-vacancy. Net yield is typically 1.5–3pp lower after CAM, sinking fund, withholding, and vacancy. FQ % is the foreign-quota inventory share — the % of currently for-sale units a developer has flagged eligible for non-Thai ownership.
