Khlong Sam Wa, Sai Mai, and Bang Khae, located on the outskirts, are the most populated districts in Bangkok, with comparatively low rental prices. In contrast, rather expensive areas around Wireless Road, upper and lower Sukhumvit, Sathorn, and Silom are particularly sought after by high-income residents and working expatriates. Bangkok’s housing prices Local buyers are facing difficulties as a result of Bangkok's increasing interest rates, which have reduced house affordability, as well as a lack of confidence in the economy.
