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

The Base Ratchada 19 offers a solid mid-town rental play from a reputable developer, with strong MRT proximity and small units well suited to the area's tenant pool, though pricing is at market rate and the district faces meaningful condo supply competition.

Strengths

Walkable (~5 min) to MRT Ratchadaphisek, reinforcing rental demand
Small, investor-friendly 23-35 sqm 1BR units suit young professionals and tenants near nearby office clusters (Thai Airways HQ, TMBThanachart HQ)
Sansiri is a proven, SET-listed developer with strong delivery track record
Construction already 50% complete, reducing delivery risk ahead of 2026 handover

Watch out for

All-1BR unit mix limits diversification and appeal to families or larger-space buyers
Ratchada has substantial existing condo supply, creating competition for tenants and resale
Low-rise 8-floor building with 614 units means high density per footprint, which could pressure facility usage and resale differentiation
