Walk through any major condo corridor in Bangkok right now, whether it's the cluster of towers along Rama 9 or the seemingly endless developments lining Sukhumvit past On Nut, and you'll notice something hard to miss. Building after building has banners screaming promotions. Lobbies have leasing desks practically begging you to come take a look. The reality is simple: Bangkok has more condos than it knows what to do with, and if you're a renter, this is genuinely one of the best moments in recent memory to lock in a great deal.

How Did Bangkok End Up With So Many Empty Condos?

The building boom really kicked off around 2017 and 2018. Developers were racing to snap up land near new BTS and MRT extensions, launching project after project along corridors like the Yellow Line and the Orange Line route through Lat Phrao and Ramkhamhaeng. The assumption was simple: build it, and Chinese investors plus local buyers will come.

Then COVID happened. International buyers vanished almost overnight. Local demand softened. But the projects that broke ground in 2018 and 2019 kept being delivered, because you can't exactly pause a 40 story tower mid-construction. The result? Tens of thousands of new units hitting the market in 2023 and 2024 with not nearly enough buyers or tenants to fill them.

Research from CBRE and Knight Frank Thailand has consistently pointed to vacancy rates above 20% in certain areas, particularly in the Rama 9 to Ratchada corridor and outer Sukhumvit zones past Bearing. One building I personally know well, Aspire Sukhumvit 48, had so many empty units at one point that the common area pool felt like your own private resort. That's the kind of oversupply we're talking about.

Where the Best Deals Are Hiding Right Now

Not every neighborhood is equally affected. The glut hits hardest in areas where developers over-built near new transit lines before ridership caught up. If you want maximum bang for your baht, these zones deserve your attention.

The Rama 9 and Ratchadaphisek area is ground zero. Buildings like Life Asoke Rama 9, Ideo Mobi Asoke, and The Line Asoke Ratchada are all competing fiercely for tenants. A one-bedroom unit that might have listed at 18,000 to 20,000 THB per month two years ago can now be found for 13,000 to 15,000 THB. That's a real drop.

Out along Sukhumvit past On Nut, the story is similar. Near Bang Chak and Punnawithi BTS stations, projects like Ideo Sukhumvit 93 and Whizdom Essence are offering first month free, waived common fees, and fully furnished units at 10,000 to 12,000 THB for a decent one-bedroom. Two years ago, those same units were going for 14,000 THB without negotiation.

Even in more central areas like Thong Lo and Ekkamai, landlords are getting more flexible. You probably won't find rock bottom prices, but you will find owners willing to throw in furniture upgrades, cover the building's internet package, or agree to shorter lease terms. A two-bedroom at Noble Reveal on Sukhumvit 63 recently rented for 32,000 THB, a price that would have been laughed at by the owner in 2019.

What This Actually Means at the Negotiating Table

Here's the part that matters for you as a renter. The power dynamic has flipped. Landlords used to hold all the cards in popular areas. Now? They're competing with dozens of identical units in the same building, and they know it.

I recently helped a friend look for a place near Phra Ram 9 MRT. We visited five buildings in a single afternoon. Three owners offered one month free rent on a 12 month lease without us even asking. One offered two months free if my friend signed that week. The desperation is real, and it works in your favor if you're willing to compare options and push back on pricing.

Practical tips that are working right now: always ask for at least one month free rent on any lease of 12 months or longer. Request that the owner cover common area fees, which typically run 1,500 to 3,000 THB per month. If the unit doesn't have a washing machine, ask for one to be installed. Owners would rather spend 8,000 THB on an appliance than lose a tenant to the building next door.

Will the Glut Last or Should You Act Now?

The honest answer is that oversupply in Bangkok is not going away overnight. New completions are still being delivered through 2025, particularly in the Lat Phrao, Ratchayothin, and outer Sukhumvit corridors. Developers have slowed new launches significantly, but the pipeline from previous years still has plenty of units coming.

That said, some correction is happening. Tourism recovery has brought back short term rental demand. Some buildings that were ghost towns in 2022 are slowly filling up as expat numbers climb back toward pre-COVID levels. Areas closest to BTS and MRT stations with proven ridership, think Asoke, Phrom Phong, and Sala Daeng, will tighten up first.

The sweet spot for renters is probably right now through mid 2025. After that, the most desirable buildings will start to fill, and landlords will regain some pricing power. The outer zone deals might persist longer, but the best centrally located bargains are already starting to get snapped up.

How to Make This Market Work for You

The single smartest thing you can do in a market like this is compare aggressively. Don't fall in love with the first unit you see. Visit at least three to five buildings. Get competing quotes. Tell landlords you're looking at other options in the same neighborhood, because you almost certainly are.

Know your walk score to the nearest BTS or MRT. A unit that's 50 meters from Punnawithi BTS is worth more than one that's 800 meters away, even if they're in the same price range. Factor in common fees, electricity rates (building rate versus MEA direct), and the actual age of appliances in the unit.

Bangkok's condo glut is a rare window where the market genuinely favors the person signing the lease. If you're searching for a condo right now, or your current lease is coming up for renewal, use this moment. Compare buildings, push on price, and don't settle for a mediocre deal when a great one is sitting three floors up or one soi over.
