Parking spaces account for approximately 40% of total units.

The Base Park East Sukhumvit 77 in 2026 shows a stable resale market supported by the On Nut-Phra Khanong rental base. Demand is driven by office workers and expats seeking practical units near lifestyle nodes along Sukhumvit, with access anchored by BTS On Nut (approx. 1.3 km). Upside is moderated by strong competing supply in nearby Sukhumvit 50-89, so pricing tends to move gradually rather than spike.

• Resale price per unit (1-bed 30-32 sq.m.): about THB 3.35-3.95M
• Resale price per sq.m.: about THB 112,000-128,000
• Average rent (1-bed): about THB 14,000-17,000 per month

Rental Yield calculation (quick): 31 sq.m. unit priced at THB 3.60M, rented at THB 16,000 per month. Annual rent = 16,000 x 12 = THB 192,000. Yield = 192,000 ÷ 3,600,000 = 5.33% per year (before common fees and taxes).

Capital Gain view: For mid-market condos in the On Nut area, a realistic appreciation assumption is 2-4% per year under normal conditions, equivalent to roughly THB 70,000-140,000 annually on a THB 3.5M asset. Execution matters: renovated, fully-furnished units typically shorten vacancy and protect achievable rent, which is key when supply competition is high.
