The Prime Suites

The Prime Suites is a condominium project located at 17 Khlong Tan, Khlong Toei, Bangkok 10110, in the Sukhumvit 24 area near Phrom Phong and Thonglor. The location is well known for its convenient city access and strong residential demand among both Thai residents and expatriates. The project was completed around 1994 and developed under The Prime Suites Condominium. It is a high-rise residential building with 1 building, 8 floors, and around 50 units, offering a relatively private living environment compared with larger condominiums in the same neighborhood.

The unit mix focuses on spacious layouts suitable for long-term living, including 1-bedroom, 2-bedroom, and 3-bedroom types. Units are generally larger than many newer developments in central Sukhumvit. Facilities include a swimming pool, fitness room, passenger lift, parking area, and common spaces for residents.

Security features include CCTV, security guards, and controlled building access. Property management is handled through the condominium juristic person responsible for common area maintenance and resident services. One of the key strengths of this project is its quiet atmosphere and large unit sizes, which remain attractive in the inner Sukhumvit market. The project is located about 1.7 km from BTS Phrom Phong and about 1.8 km from BTS Thong Lo, making it suitable for both owner-occupiers and rental investors targeting expatriate tenants.

The Prime Suites in Khlong Toei-Rama 4 remains a “mid-city, still attainable” resale option in 2026. Versus inner Sukhumvit benchmarks like Siri at Sukhumvit or Noble Ploenchit, its pricing per sq.m. is typically lower, which helps both entry cost and rental competitiveness.

• Resale price per unit: 1-bedroom 35 sq.m. averages THB 4.55M
• Price per sq.m.: average THB 130,000 (commonly THB 120,000-145,000)
• Average rent: 1-bedroom 35 sq.m. averages THB 18,000 per month (range THB 16,000-22,000)

Rental Yield (2026) quick math: (18,000 x 12) minus 1 vacant month = THB 198,000 net rent/year. Divide by purchase price THB 4,550,000 = about 4.35% p.a. This is a reasonable yield for a near-CBD location, supported by tenant demand from Rama 4-Asoke office clusters.

Capital Gain outlook: For Khlong Toei-Rama 4, price growth tends to be steady rather than explosive. A realistic expectation is 2-4% p.a. over the next 12-24 months, driven by genuine rental demand and new supply pushing the area’s price floor upward. Key risk: newer launches along Rama 4 (for example, Aspire Sukhumvit-Rama 4) may temporarily pressure achievable rents during promotional periods, so investors should underwrite conservatively.
