Buying apartments and condominiums in Bangkok: a buyer's decision guide

Start with the legal asset, not the listing

In Bangkok, an advertisement for an “apartment” may describe a unit in a registered condominium, a unit offered for rent in a single-owner apartment building, or an interest sold through a lease or contractual structure. These are not interchangeable purchases. A registered condominium may permit separately registered ownership of a specific unit together with an interest in common property; renting an apartment does not create that title. Obtain the proposed instrument and condominium registration details before treating “freehold,” “ownership,” or “99-year arrangement” as a proven legal right. This guide concerns a buyer selecting and verifying a particular unit and its shared building, not available inventory or investment-return forecasts.

Define the intended use first: full-time home, occasional base, or longer-term letting. Set a maximum all-in acquisition budget in Thai baht (THB), a tolerable recurring-cost ceiling, essential bedroom and working space, acceptable commute at actual travel hours, and non-negotiable access or noise requirements. Request a floor plan with usable and registered areas clearly identified, not just a marketing area. Ask who may occupy the unit, whether pets or alterations are permitted, and whether parking, storage and furniture are included by right, by allocation, by licence, or merely as a current practice. A promised amenity is not the same as an enforceable unit-specific entitlement.

Compare the building as carefully as the unit

Shortlist units with the same use case, not merely the same asking price. Inspect daylight and heat exposure, water pressure, ventilation, lift capacity, escape routes, structural or moisture defects, acoustic separation, accessibility and mobile/internet coverage. Visit at a second time of day. Check access to BTS/MRT or the actual route, rather than a brochure's straight-line distance. In Bangkok, street access during heavy rain, drainage history, neighbouring construction and traffic noise can matter more than a distant skyline view. Commission independent technical inspection where the age, condition or risk justifies it; photographs and a seller's assurances are not substitutes.

Record each candidate's registered unit area, price per comparable square metre, verified sale terms and what is excluded. A larger advertised “gross” area cannot be compared directly with a smaller registered private area. Confirm the developer or seller's authority, expected completion status for off-plan units and the actual inspectable condition for resale units. Avoid interpreting showroom finishes or amenities as guaranteed specifications unless incorporated into the binding documents. Price history, live availability and achievable rent require separate current evidence; none is established by this guide.

Foreign-buyer eligibility and the 49% test

For a foreign purchaser seeking condominium freehold, Thailand's Condominium Act framework generally limits the aggregate area of foreign-owned condominium units to 49% of the total area of units in the registered building; it is not a quota of 49% of apartments by count. The condominium juristic person should provide a current foreign-quota certificate for Land Department registration. Buyer eligibility and source-of-funds evidence also matter. A foreign purchaser must establish the relevant statutory eligibility route; nationality alone does not make any unit transferrable. Ask a Thai property lawyer to verify the actual quota and route against the unit and buyer before money becomes non-refundable. A unit currently owned by a Thai seller does not automatically become eligible for foreign freehold if the building's foreign-area quota is already exhausted; request written evidence of available capacity. [S1] [S2]

Foreign condominium ownership should not be confused with ownership of the underlying land. Land acquisition by foreigners is subject to separate restrictions and exceptional statutory routes, not a routine benefit of buying an apartment. Do not assume that a Thai nominee shareholder, an informal corporate wrapper, a lease marketed as perpetual, or a promise of automatic renewal lawfully recreates unrestricted freehold. For a resale condominium, inspect the unit title and land-office record for registered owner, mortgages, attachments and other encumbrances; for an off-plan purchase, verify project registration, land/project documents, milestones and contractual protections before paying. [S3] [S4]

Rights inside the unit and liabilities outside it

Ask for the registered unit plan, condominium regulations and a written schedule of any parking or storage entitlement. Identify walls, balconies, shafts, windows, external façade, structural parts and shared equipment: the advertised 'private' use of an area may not give permission to alter or exclusively own it. Check restrictions on renovation, façade work, pets, guests, letting, noise and moving furniture. The right answer is the actual registered/contractual documentation and applicable building rules, not assumptions taken from condominium practice elsewhere. A sought-after rental strategy is unsuitable if the relevant permissions cannot be established. If short stays are part of the plan, check applicable hotel or licensing requirements as well as condominium letting rules; an online booking listing is not proof of permission.

Review at least the most recent available audited or approved accounts, current budget, maintenance-fee schedule, sinking or reserve-fund position, owner arrears, insurance scope, manager's authority, meeting minutes, litigation and proposed capital projects. Ask the juristic person whether lifts, fire systems, waterproofing, façade or pool plant need major spending and whether special contributions have been approved or discussed. Calculate the cost per month and per unit-area on comparable inclusions, then add metered utilities, insurance, property-related taxes where applicable and a realistic reserve for unit repairs. Cheap fees can signal underfunding, while expensive fees may fund genuine services; neither number proves quality by itself.

An absence of common-expense debt is important at transfer, but a debt-free certificate does not prove a well-funded building or absence of future work. The Land Department explains that, for condominium transfers, Section 29 requires an up-to-date confirmation from the condominium juristic person that relevant Section 18 expenses are paid; authority of the certificate signatory also matters. Confirm timing and issuance with the actual land office and juristic person. Retain separate documentary evidence of parking, sinking-fund obligations and any outstanding special assessments. [S5]

Calculate the transaction cost and preserve the payment trail

For a foreign buyer using the inward-remittance eligibility route, arrange the funds with the receiving Thai bank before transfer. Government guidance describes transferring foreign currency into Thailand with the condominium purchase purpose, project, unit and buyer name recorded, and obtaining the required foreign exchange transaction evidence or bank certificate. It describes a USD 50,000 (or equivalent) threshold for a Foreign Currency Transaction Form, with bank certification for smaller amounts; certain other statutory routes, including qualifying permanent-resident situations, have different evidence. Confirm the applicable rule, documentation format, beneficiary account and bank processing before sending any deposit. Preserve SWIFT/payment records and account for the exchange-rate reference, conversion spread, intermediary fees and receiving-bank charges. For this remittance-based route, have the bank and Thai counsel confirm that the qualifying funds evidenced cover the entire unit price, not merely the deposit. [S6]

A useful acquisition worksheet has separate lines for agreed THB price, deposit, transfer registration, any mortgage fees, potentially applicable withholding tax, specific business tax or stamp duty, legal and technical checks, bank/FX costs, common-fee adjustment, sinking-fund contributions and handover costs. The standard condominium/real-property registration transfer fee is generally 2% of the official appraised value, but reductions and eligibility rules can change; allocation between seller and buyer is contractual and should be written down. A temporary reduction of the registration fee has been reported for qualifying Thai individual buyers of lower-priced homes; it is not a blanket reduction for foreign buyers, so confirm any current concession with the Land Department. Confirm live eligibility with the land office before a fee quote. A corresponding temporary relief on mortgage registration has also been reported; confirm current rates with the Land Department. [S7] [S8]

Do not treat the advertised price as the total price. As a purely illustrative comparison, THB 12,000,000 plus THB 100,000 in annual building and unit running costs has a different affordability profile from THB 11,500,000 plus THB 180,000 annually. These invented figures are not Bangkok market data and do not predict resale value. Over five years, the difference in the stated recurring costs alone is THB 400,000, before escalation, repairs, financing and opportunity cost; the more expensive unit upfront may still be preferable, depending on physical quality and use. Obtain itemised actual quotations and check whether all amounts use the same currency date and exchange-rate basis. On these stated assumptions, price plus five years of running costs totals THB 12,500,000 for the first unit and THB 12,400,000 for the second—a difference of just THB 100,000 before all other costs.

Move from a shortlist to a controlled transfer

1. Before reservation: obtain the exact title/contract, buyer and seller identities and authority, registered area, foreign-quota evidence if applicable, construction status, rules, fee schedule and requested inspection access. Reject pressure to pay merely for access to basic documents.
2. Before the deposit becomes non-refundable: arrange an independent Thai-law title and contract review, unit/building inspection, management-record review and funding-bank check. Write objective conditions covering clean title, eligibility, quota, clear debt status, approved financing if needed, material defects and a realistic document-delivery timetable.
3. Before signing: identify the seller's exact performance obligations, handover state and inventory, deposit holder and refund triggers, late completion or seller default remedies, taxes/fees allocation, dispute forum and language of the operative contract. Do not infer that paying remotely means ownership can be registered remotely.
4. At closing: have the appointed professionals verify original documents, title and charges again, fresh quota and debt-free certificates where needed, funds evidence, and the Land Department's registration requirements. Release the balance against the agreed transfer mechanics and retain the registered title, receipts, rules, keys and inventory. Power-of-attorney arrangements require approval of their form and identity formalities; never assume a scanned signature is sufficient. [S4] [S5]

The proceed, renegotiate or stop test

Proceed to a controlled offer only if the intended use is compatible with the documented rights, the buyer and unit can legally transfer, building liabilities are understood, the physical condition is acceptable and the full cost remains within budget. Renegotiate price, timetable, repairs or contractual conditions when risk is measurable and curable. Stop if no qualifying title or foreign quota can be shown, a material encumbrance cannot be cleared, remittance evidence cannot be obtained on the required route, management refuses critical financial records, or the intended use relies on an unproven right. A prestigious postcode is not a cure for any of these defects.

Keep a one-page decision file for each candidate: address and unit reference; rights and land-office verification status; comparable area and total THB cost; monthly common and variable charges; planned works and reserve position; permitted use; physical inspection results; documents still missing; and a responsible person/date for each open item. Sources below establish general Thai rules, not the status of any specific Bangkok unit. The foreign quota, tax incentives, approvals, condominium records and financing terms must be checked again for the actual transaction as of its date.
