The Residences At Mandarin Oriental in Khlong Ton Sai, Khlong San is a prime riverfront luxury condominium where pricing is largely supported by scarcity of true Chao Phraya views and upper-tier rental demand. In 2026, the market tone favors long-hold leasing rather than short-term flipping, with accessibility to Sathorn-Silom and the ICONSIAM lifestyle zone acting as key demand anchors.

• 2026 resale pricing: a typical 2-bedroom around 120 sq.m. averages THB 62,000,000, or roughly THB 520,000 per sq.m. (commonly seen range THB 480,000-600,000 per sq.m. depending on floor, view, and fit-out).
• Average rent in 2026: about THB 230,000 per month (range THB 200,000-280,000 per month for comparable 2-bedroom units).
• Rental Yield (quick math): (230,000 x 12) - 62,000,000 = 2,760,000 - 62,000,000 = 4.45% per year (gross, before common fees, taxes, and vacancy).

Capital gain outlook: using a conservative 3-5% annual appreciation from a 2026 base, resale values could reach THB 69-72 million within 3 years (about 7-16% capital gain). Upside drivers include limited riverfront supply and international tenant-buyer interest, while key risks are macro cycles and higher holding costs. This profile suits investors prioritizing asset quality and stable cashflow over rapid resale.
