The Key Rama 3

The Key Rama 3 is located at 348 Bang Khlo, Bang Kho Laem, Bangkok 10120, on Rama 3 Road near Thanon Tok junction and within convenient reach of Sathorn - Silom business district. The location suits both residential living and rental investment thanks to easy access to the city.

This condominium is a High Rise project developed by Land and Houses Public Company Limited and completed around 2013. The project consists of 1 building with 38 floors and approximately 484 residential units. Parking is available for around 60% of total units. Unit types include 1-bedroom, 2-bedroom, and duplex layouts, with sizes starting from about 30 - 90 square meters depending on the room type.

Facilities include a swimming pool, fitness center, garden, multipurpose room, lobby, and passenger lifts. The security system includes 24-hour security guards, CCTV, and key card access control.

In terms of management, the common area and building systems are maintained to the standard typically seen in large condominium developments by the developer. This makes the project appealing for buyers seeking a Rama 3 condo with some river views, good road connectivity, and access to nearby shopping centers, international schools, and office buildings. A notable nearby project is Star View Rama 3.

The Key Rama 3 in 2026 sits in the “value-for-money” segment of the Rama 3 corridor, benefiting from tenant demand linked to Sathorn-Silom offices and riverside lifestyle zones. Pricing is generally less stretched than premium riverfront projects (e.g., Star View Rama 3), which supports a cashflow-first rental strategy.

• Average resale price per unit: THB 2.65M (1-bedroom, 33 sq.m.)
• Average price per sq.m.: ~THB 80,000 (2,650,000 - 33)
• Average rent: THB 12,000 per month (1-bedroom 32-35 sq.m.)

Rental Yield (shown): Annual rent = 12,000 x 12 = THB 144,000. Gross yield = 144,000 - 2,650,000 = 5.43% per year (before common fees, taxes, and vacancy).

Capital Gain outlook: For mid-market condos along Rama 3, a realistic appreciation pace is typically gradual. Assuming 2-4% per year over 2026-2028, that implies a price increase of roughly THB 53k-106k per year per unit. Total return becomes more attractive when buying below the project’s average and securing stable tenants from Sathorn, Charoen Krung, and nearby business clusters.
