Sukhumvit Condo Prices Per Sqm 2026: Full Buyer Guide
By THAI.ESTATE Editorial Team13 min read
Sukhumvit is Bangkok's most active condo market for foreign buyers. As of 2026, market estimates place resale condo prices along Sukhumvit at 80,000 to 250,000 THB per square metre, depending on the sub-district (known locally as 'soi'), building age, and proximity to a BTS Skytrain station. New launches in prime lower Sukhumvit corridors (Sois 1-31 on the Asok-Phrom Phong stretch) sit at the upper end of that range, while older buildings further out along upper Sukhumvit (Sois 71-107) can trade well below 100,000 THB per sqm.
This guide breaks down prices by zone, explains what drives the premium, and tells you honestly who should and who should not buy here.
Quick answer
- Lower Sukhumvit (Sois 1-33, Asok to Phrom Phong): 130,000 - 250,000 THB per sqm for new or recently completed condos, as of 2026 market estimates
- Mid Sukhumvit (Sois 39-63, Thong Lo to Ekkamai): 110,000 - 200,000 THB per sqm; a lifestyle premium applies in Thong Lo
- Upper Sukhumvit (Sois 71-107, On Nut to Bearing/Samrong): 70,000 - 130,000 THB per sqm; best yield-to-price ratio in the corridor
- Foreign buyers can legally hold a freehold condo title (chanote - a full ownership land certificate issued to the unit owner) under the Condominium Act, provided foreign ownership in the building does not exceed 49% of total floor area
- Rental yields across Sukhumvit run at roughly 4% to 6% gross per year (market estimates, 2026), with short-stay-permitted buildings at the higher end
- Transfer fee is 2% of the registered value, split by negotiation; withholding tax and specific business tax apply on resale
- BTS station proximity adds a measurable premium: units within 300 metres of a station typically command 10% to 20% more than equivalent units 800 metres away
Options and scenarios
Lower Sukhumvit (Asok, Nana, Phrom Phong) - who is this for?
This zone covers roughly Sukhumvit Sois 1 to 33, anchored by the Asok BTS/MRT interchange and the Phrom Phong BTS stop. It is Bangkok's most internationally recognisable address.
Price range (2026 estimates): 130,000 - 250,000 THB per sqm for new builds; 100,000 - 180,000 THB per sqm for resale stock built after 2010.
A 35 sqm studio in a new building near Asok will cost roughly 4.5 million to 7 million THB. A 60 sqm one-bedroom near Phrom Phong will range from 7 million to 14 million THB, depending on floor and view.
The tenant base here is corporate expatriates, embassy staff, and short-stay visitors. Occupancy in well-managed buildings stays above 80% for most of the year, though the 49% foreign quota fills fast in new launches, so check the current foreign quota availability before committing.
Who should buy here: buyers who want liquidity, a deep tenant pool, and a Bangkok address that is easy to resell. Also buyers who plan to use the unit personally and value walkability to the BTS, EmQuartier, and Emporium malls.
Who should not buy here: buyers with a budget under 4 million THB (units at that price point in this zone are rare and often very small), buyers seeking high gross yields (the premium purchase price compresses yields), and buyers who want a quiet, low-density neighbourhood.
Mid Sukhumvit (Thong Lo, Ekkamai) - who is this for?
Thong Lo (Soi 55) and Ekkamai (Soi 63) have a distinct character: upscale restaurants, Japanese supermarkets, and a younger, design-conscious resident mix that includes Bangkok's urban Thai middle class and long-stay Japanese expats.
Price range (2026 estimates): 110,000 - 200,000 THB per sqm for new or post-2015 buildings. Thong Lo carries a lifestyle premium of roughly 10% to 15% over Ekkamai for comparable stock.
A 50 sqm one-bedroom in Thong Lo will typically run 6 million to 9 million THB. Ekkamai offers similar sizes from 5 million to 7.5 million THB.
The rental market here skews toward long-stay tenants: remote workers, Japanese families, and Thai professionals. Short-term rental rules in Bangkok (minimum 30-night stays in most condo juristic persons - the building management entity) mean you cannot run Airbnb-style lettings legally in most buildings here. Gross yields in the 4% to 5.5% range are typical.
Who should buy here: buyers who want a liveable, walkable area with good food, a BTS connection, and a stable long-term tenant base. Also buyers who plan to live in Bangkok part of the year.
Who should not buy here: buyers whose entire return model depends on short-term rental income (the juristic person rules make this difficult), and buyers expecting Phrom Phong-level capital appreciation on a Ekkamai budget.
Upper Sukhumvit (On Nut, Phra Khanong, Bearing, Samrong) - who is this for?
Upper Sukhumvit from On Nut (Soi 77) outward to Samrong has changed substantially since the BTS extended this far. It is now a practical, affordable zone popular with Thai middle-class buyers, young professionals, and budget-conscious expats.
Price range (2026 estimates): 70,000 - 130,000 THB per sqm. New launches near On Nut BTS sit at 100,000 - 130,000 THB per sqm. Older buildings (pre-2010) trade at 70,000 - 90,000 THB per sqm.
A 35 sqm studio near On Nut BTS can be found from 2.8 million to 4.5 million THB. A 60 sqm one-bedroom runs 4 million to 7 million THB.
Gross rental yields here are the highest on the Sukhumvit corridor: 5% to 6.5% is achievable (market estimates, 2026) because purchase prices are lower while rents have risen as tenants price out of Phrom Phong. The tenant base is mixed: Thai renters, young expats, digital nomads, and hospital staff from nearby Sukhumvit Hospital.
Who should buy here: yield-focused buyers, first-time Bangkok investors with a budget of 3 million to 6 million THB, and buyers who want BTS access without paying lower-Sukhumvit prices.
Who should not buy here: buyers who prioritise resale liquidity to international buyers (the upper Sukhumvit resale market is thinner internationally), and buyers who want a premium address for short-term personal use when visiting Bangkok.

Risks and mistakes
The 49% foreign quota trap
Under the Condominium Act, no more than 49% of a building's total floor area can be held by non-Thai nationals. In popular lower Sukhumvit buildings this quota fills during pre-sales. If a developer or agent tells you a quota slot is 'reserved' for you, verify this in writing with the building's juristic person or the Land Department before signing anything. Buying a unit when the foreign quota is full means you cannot register ownership under your name as a foreigner.
Off-plan currency and delivery risk
Many Sukhumvit condos are sold off-plan, with completion 2 to 4 years after signing. You pay in instalments during construction. If the developer delays or the project is cancelled, recovering funds is a legal process in Thailand, not an automatic refund. Check the developer's track record of completed projects before committing. Use a qualified Thai property lawyer (not the developer's in-house counsel) to review the sales and purchase agreement.
Oversupply in specific pockets
The On Nut to Phra Khanong corridor saw a wave of new supply between 2019 and 2024. Vacancy rates in some buildings in this zone remain above 20% as of market estimates for early 2026. Do not assume rental income from day one of ownership in a new building. Budget for at least 3 to 6 months of vacancy while the building fills.
Short-term rental rules
Bangkok does not permit short-stay rentals (under 30 nights) in residential condominiums under the Hotel Act. The building's juristic person can and does enforce this. Projects marketed as 'investment condos with rental management' often rely on this grey area. If your yield calculation requires short-stay income, the legal risk is material.
Transfer costs and taxes
Buyers frequently underestimate transaction costs. For a resale unit, total costs can reach 3% to 7% of the purchase price when you include the 2% transfer fee (split by negotiation), specific business tax (3.3% on the registered value, paid by the seller within 5 years of their purchase but sometimes passed to the buyer by contract), withholding tax, and stamp duty. Get a full cost schedule from your lawyer before signing.
Currency risk
If you earn in euros, pounds, or US dollars, a strengthening Thai baht reduces your effective yield when converting rental income back to your home currency. This is a real risk over a 5 to 10 year hold period.
Construction noise corridors
Sukhumvit is an active construction zone in 2026. Several large mixed-use projects are under construction along Sois 16, 38, and the On Nut area. If you are buying for personal use or renting to noise-sensitive tenants, visit the immediate surroundings of any building at different times of day before committing.
FAQ
How much does a condo cost per sqm in Sukhumvit in 2026?
As of 2026, market estimates put Sukhumvit condo prices at 80,000 to 250,000 THB per square metre. The range depends on the zone (lower, mid, or upper Sukhumvit), whether the unit is new or resale, and how close the building is to a BTS station. Lower Sukhumvit near Asok and Phrom Phong commands the highest prices.
Can a foreigner own a Sukhumvit condo freehold?
Yes. Under the Thai Condominium Act, a foreign national can hold a freehold condominium title (chanote) provided the total foreign-owned floor area in the building does not exceed 49%. You need to bring funds into Thailand from abroad and obtain a Foreign Exchange Transaction (FET) certificate - a document from your Thai bank confirming the inward transfer - to register the purchase at the Land Department.
What is the Foreign Exchange Transaction certificate and why does it matter?
A Foreign Exchange Transaction (FET) certificate is a document your Thai bank issues when you transfer foreign currency into Thailand and convert it to Thai baht. The Land Department requires this document to register a condo in a foreign buyer's name. Without it, you cannot complete the purchase under the foreign quota. Keep the original; you will also need it when you eventually sell.
What gross rental yields can I expect in Sukhumvit in 2026?
Market estimates for 2026 suggest gross yields of 3.5% to 5% in lower Sukhumvit, 4% to 5.5% in mid Sukhumvit (Thong Lo, Ekkamai), and 5% to 6.5% in upper Sukhumvit (On Nut, Phra Khanong). Net yields after maintenance fees, property management fees (typically 8% to 12% of rent), and vacancies will be lower. Treat published yield figures from developers as gross, pre-cost numbers.
Is Thong Lo or Phrom Phong better for investment?
They serve different buyer profiles. Phrom Phong offers stronger resale liquidity to international buyers and a deep corporate expat tenant base but lower gross yields because purchase prices are high. Thong Lo offers a lifestyle premium, a stable long-stay tenant base, and slightly better yields, but the resale pool is narrower. If capital growth and exit speed matter more, Phrom Phong is the safer choice. If you plan to hold for income over 7 to 10 years, Thong Lo is a reasonable option.
What are the transaction costs when buying a Sukhumvit condo?
Budget for 3% to 7% of the purchase price in total transaction costs. Key line items: 2% transfer fee (shared by negotiation between buyer and seller), 3.3% specific business tax on the registered value if the seller has owned the unit for under 5 years (sometimes passed to the buyer by contract), stamp duty (0.5%, only applies if specific business tax does not), and withholding tax (paid by the seller but affects net proceeds). Your lawyer should give you a full cost schedule before you sign.
Are there sinking fund and maintenance fees I should factor in?
Yes. A sinking fund (a one-time reserve payment for major building repairs) is charged at purchase, typically 400 to 800 THB per sqm in Bangkok condos. Monthly common area maintenance fees (CAM fees) run from 40 to 100 THB per sqm per month depending on building quality and facilities. For a 50 sqm unit, that means 2,000 to 5,000 THB per month in ongoing fees before any other costs.
Is On Nut a good area to buy a condo in 2026?
On Nut is a practical choice for yield-focused buyers. BTS access is good, the local infrastructure is developed, and purchase prices are significantly lower than Phrom Phong or Thong Lo. The trade-off is that the resale market is thinner for international buyers, and some buildings in the area carry above-average vacancy because of recent oversupply. Inspect specific building occupancy rates before buying, and do not rely on developer yield projections.
What happens if the foreign quota in my building is already full?
You cannot register the unit in your name as a foreign national under the Condominium Act. Some buyers in this situation purchase through a Thai company structure, but this carries legal complexity and ongoing compliance costs. A Thai spouse holding the title is another route, but it has its own legal and personal risks. Both structures require independent legal advice. The simplest answer is to choose a building where foreign quota is available.
How do I verify the foreign quota availability before I buy?
Request a written statement from the building's juristic person (the legally registered management entity for the condominium) showing the current total floor area, the foreign-owned floor area, and the remaining available quota. The Land Department can also confirm this. Do not rely on verbal assurances from the developer's sales team. Make quota verification a condition before you pay any reservation deposit.
