Citi Smart Sukhumvit 18

Citi Smart Sukhumvit 18 is a high-rise condominium located at 366 Soi Sukhumvit 18, Khlong Toei, Bangkok 10110, in the prime Asok-Phrom Phong area. The project offers convenient access to BTS Asok, approximately 650 meters away, and MRT Sukhumvit, around 700 meters away. This location is well suited for both end-users and investors due to its strong connectivity to Sukhumvit Road, Asok Montri Road, and the expressway network.

Developed by City Resort Group, the project consists of 1 residential building with 21 floors and approximately 192 units. It was completed in 2008. Unit types include 1-bedroom, 2-bedroom, and penthouse layouts, with relatively spacious living areas compared with many condominiums in the same central district. Parking is available for residents based on the project's allocation.

Facilities include a swimming pool, fitness center, sauna, garden, lobby, passenger elevators, and common areas designed for daily living. The security system includes 24-hour security guards, key card access, CCTV, and controlled building entry, supporting a comfortable and secure residential environment.

In terms of management, the project is known for ongoing building and common area maintenance. Its central Sukhumvit location enhances both residential convenience and rental potential, with nearby amenities such as Terminal 21, Emporium, EmQuartier, Benjakitti Park, and multiple office buildings.

Citi Smart Sukhumvit 18 in 2026 sits in the established Asok-Phrom Phong rental pocket, supported by expat tenants and office demand. Access remains a key driver: BTS Asok is about 900 m away and MRT Sukhumvit about 1.0 km, helping prices stay resilient versus newer, higher-priced launches nearby.

• Resale price per unit (sample 1-bed 45 sq.m.): THB 7.2-8.2M
• Average resale price: THB 165,000-185,000 per sq.m.
• Average rent: THB 30,000-38,000 per month (1-bed 40-50 sq.m.)

Rental Yield calculation (quick): assume purchase at THB 7.8M and rent at THB 34,000 per month. Annual rent = 34,000 x 12 = THB 408,000. Gross yield = 408,000 ÷ 7,800,000 = 5.23% per year (before common fees, taxes, and vacancy).

Capital gain view: With new supply around Asok-Thonglor often priced higher per sq.m., this project can benefit from relative affordability and steady rental liquidity. A realistic capital appreciation range is 2-4% per year for well-maintained units, implying roughly THB 150,000-300,000 annual price upside on a THB 7-8M unit, provided market sentiment remains stable and the unit stays competitive in condition and furnishings.
