Est. gross rental yield: 5–6.5% per yearGrowth outlook: HighSuits: Rental investor · Own-stay buyer

The Base Wongsawang offers solid transit connectivity via MRT Wongsawang and exposure to Bang Sue's high-growth transit-hub story, backed by Sansiri's reliable delivery record. Investors should weigh the 2027 completion timeline and dense unit count against attractive entry pricing and rental-friendly small unit sizes.

Strengths

Located next to MRT Wongsawang (Purple Line), with easy access to the emerging Bang Sue Grand Station transit hub
Sansiri is a proven, SET-listed developer with a strong delivery track record
Small, affordable unit sizes (25-46 sqm) are well-suited to rental demand and first-time buyers
Located in a high-growth district benefiting from major government transport infrastructure investment

Watch out for

Still under construction with completion not until 2027, carrying moderate delivery-timeline risk
High density (684 units, 40 floors) means significant competing rental/resale supply within the same project
Small unit sizes limit appeal to larger households and may cap long-term capital appreciation
