Yet landlords in those same neighborhoods are fielding more rental inquiries than they did two years ago, and quality units are filling within days of listing. Supply is climbing and demand is holding firm, which sounds like a contradiction until you look at who is actually renting, and why.

The Numbers Behind the Building Boom

Thailand's Real Estate Information Center reported that over 60,000 new condo units were launched across Greater Bangkok in 2023 and 2024 combined. Developers like Ananda, SC Asset, and AP Thailand have been racing to capture demand from both local buyers and foreign investors, particularly from China, Taiwan, and increasingly the Middle East.

Much of the new supply concentrates in specific corridors. The eastern Sukhumvit stretch between BTS Ekkamai and BTS Udom Suk has seen a cluster of launches in the 3 to 5 million baht range. The Ratchadaphisek corridor near MRT Thailand Cultural Centre is filling up with mid-rise projects, and Bang Na now hosts multiple high-rise developments targeting the Eastern Economic Corridor crowd.

But higher supply does not automatically mean lower rents or weaker demand. The situation is more nuanced, and the data on who is actually renting explains most of it.

Why Rental Demand Is Not Softening

Bangkok has seen a sustained influx of digital nomads, regional expats, and remote workers over the past three years. The Long-Term Resident visa introduced in 2022, along with its ongoing refinements, has made it easier for skilled foreigners to stay legally for extended periods. Many of them rent rather than buy, especially while they are still testing the city before committing to something longer.

Take Thong Lo, specifically the sois running between BTS Thong Lo and BTS Ekkamai. A well-furnished 35 sqm studio that rented for 18,000 baht per month in 2021 now commands 22,000 to 25,000 baht, and quality units still fill within days of listing. The renter profile has shifted: fewer long-stay tourists stretching a visa, more professionals earning Singapore or European salaries and working remotely from a Bangkok base.

Thai professionals are also choosing to rent longer. Rising property prices have pushed homeownership further out of reach for younger Bangkok residents, so renting a well-located condo near the BTS or MRT has become the practical long-term choice for a growing share of the city's workforce.

New Supply Is Not Always Competing With Existing Rentals

One detail that gets missed in the headline numbers is that new condo launches and the active rental market are not perfectly overlapping categories. A significant portion of newly launched units are sold to owner-occupiers who move in and never put their place on the rental market at all.

Another portion goes to Thai investors who hold units for capital appreciation and delay renting for months, sometimes longer. The Nue District Rama 9 project near MRT Phra Ram 9 is a clear example. It launched in late 2023 with strong takeup from Thai buyer-investors, yet as of early 2025 a meaningful share of transferred units remain empty or used only occasionally for weekend stays.

That unit count appears in completion statistics but adds no pressure to the active rental supply. The pipeline is genuinely large, but the portion actually competing for tenants in any given month is considerably smaller than the raw numbers suggest.

Location Still Separates High-Occupancy Units from Vacant Ones

Even with overall demand staying strong, not every unit rents at the same speed. Bangkok's rental market rewards location specificity in a way that surprises people who are new to the city.

A condo two minutes on foot from BTS Phra Khanong can rent for 20,000 baht per month and stay occupied almost continuously. A similar unit in a newer building 800 meters from the same station, requiring a motorbike taxi or a walk down Soi 77 in the midday heat, might sit empty for weeks at that same price before the landlord adjusts down to 17,000 baht.

The gap is not about build quality or amenities. It is about last-mile friction for a tenant who commutes every day. Areas like Ari near BTS Ari, Phrom Phong near BTS Phrom Phong, and the stretch around MRT Samrong consistently command premium occupancy because transit access and walkable daily life come together in the same spot.

What This Means If You Are Renting Out a Unit

If you own or are considering purchasing a condo to rent in Bangkok, the rising supply picture actually clarifies your strategy. Tenants have more choices at every price point now, which means quality and presentation matter more than they did a few years ago.

A furnished 45 sqm one-bedroom near BTS Chit Lom, priced at 28,000 baht per month with accurate photos, fast responses from the landlord, and flexible lease terms, will consistently outperform a comparable unit listed at 25,000 baht with poor photos and slow replies. Presentation, responsiveness, and trust are where the competitive edge now lives for Bangkok landlords.

Tenants, especially expats and remote workers, are doing most of their shortlisting online before they even board a flight. The first impression happens on a listing page, not at the building lobby. That single shift changes everything about how a unit needs to be marketed.

Bangkok's condo market is genuinely compelling right now. Supply is rising, but demand is absorbing it better than many analysts predicted. The city keeps drawing in new residents across multiple categories, from tech workers and startup founders to retirees and regional expats, and the variety of new inventory gives renters real choices across more neighborhoods than before.
