Bangkok Condo Due Diligence Checklist
A structured checklist for foreign buyers reviewing a Bangkok condo before reservation, contract signing, funds transfer, and completion.
Due diligence before commitment
Due diligence should start before the buyer is emotionally committed to a unit. For foreign buyers, the checklist has four layers: legal ownership, financial terms, building quality, and investment fundamentals. A unit should pass all four before the buyer treats it as a serious purchase candidate.
| Area | Checks | Why it matters |
|---|---|---|
| Legal and title | Title deed, seller authority, encumbrances, transfer route, power of attorney, contract terms. | Prevents ownership and completion problems. |
| Foreign buyer eligibility | Foreign quota, bank remittance evidence, buyer identity documents. | Determines whether transfer can be registered properly. |
| Building management | Juristic office quality, common fee arrears, sinking fund, maintenance, facilities, insurance. | Affects rent, resale, and ownership experience. |
| Physical condition | Leaks, electrical, air-conditioning, appliances, furniture, balcony, windows, noise, view risk. | Reduces unexpected repair and tenant-readiness cost. |
| Investment evidence | Comparable sales, comparable rents, vacancy, tenant pool, competing supply, exit demand. | Separates genuine investment cases from weak marketing claims. |
Documents to request
Title and seller documents
Confirm ownership, authority to sell, and any mortgage or encumbrance position.
Juristic confirmation
Request foreign quota and common fee information where applicable.
Cost allocation
Agree transfer fee, taxes, outstanding fees, furniture, repair items, and handover date.
Rent evidence
Ask for comparable rent, tenancy history where available, and realistic furnishing assumptions.
Inspection priorities
Inspect water leakage, bathroom drainage, air-conditioning age, electrical sockets, flooring, windows, built-in furniture, kitchen appliances, balcony safety, view obstruction risk, noise, lift waiting time, parking, lobby condition, and facility maintenance. For rental investments, also inspect the unit as a future tenant would: commute, lobby, security, building smell, lift quality, parcel handling, and street-level convenience.
Red flags
Red flags include unclear quota, rushed deposit pressure, unwillingness to provide documents, old renovation hiding defects, many similar units for rent in the same building, poor juristic responsiveness, unrealistic rent claims, unresolved common fee arrears, and pricing far above comparable completed stock.
Use this checklist with the foreign quota guide, buying process guide, and rental yield guide.
FAQ
What should I check before paying a Bangkok condo deposit?
Check foreign quota, seller authority, title route, transfer costs, key contract terms, and whether the deposit is refundable under stated conditions.
Do I need a physical inspection?
Yes, especially for resale units. Photos rarely show leakage, noise, maintenance, and common-area issues fully.
Who should verify legal documents?
Use a qualified lawyer or transfer professional familiar with Thai condominium transactions and foreign-buyer requirements.
