For sale 1 bed condo in Watthana, Bangkok

A premium city residence at HQ by Sansiri, this stylish 1-bedroom corner unit offers 43.55 sqm on the 22nd floor in the heart of Thonglor-Sukhumvit, one of Bangkok’s most desirable lifestyle and rental locations. With open city and skyline views, the unit delivers a bright, elevated atmosphere above the city.
The property is sold with a tenant in place until January 2027, generating THB 30,000 per month in rental income and offering a current ROI of 4.56%. This makes it an excellent opportunity for investors seeking immediate rental returns in one of Bangkok’s strongest rental markets.
