Off-Plan or Resale Condo in Bangkok: What Should You Compare?

← Bangkok Info & Advice

An off-plan condo and a resale condo involve different trade-offs. One is a commitment based partly on plans and a contract; the other lets you inspect an existing property. Neither option is automatically the better purchase.

Understand what you can inspect

With resale, view the exact unit, its outlook and the condition of the building. For off-plan, distinguish the showroom from the specification promised in your contract. Ask which materials, appliances, ceiling heights, parking arrangements and facilities are contractually included, and what the developer can change.

Compare the payment timeline

List every reservation, contract, instalment and completion payment. Check what happens if a payment is late, financing is declined or you cannot complete. For resale, confirm how deposits and any outstanding mortgage will be handled. Have an independent adviser review the proposed arrangements before you pay.

Assess completion risk

For an off-plan purchase, ask about the project’s approvals, construction progress and the contractual completion period. Have your lawyer explain delay provisions, cancellation rights and any remedies. Marketing forecasts are not guarantees. Consider the cost of alternative accommodation if your intended move-in date slips.

Look at the operating building

For resale, ask management about repairs, maintenance funding, common-area arrears and planned assessments. Inspect lifts, parking, corridors and shared facilities. An attractive unit can sit inside a building with significant maintenance needs. A newer building also needs scrutiny; age alone is not a reliable quality measure.

Compare like for like

Use usable area, floor, orientation, furnishings, condition and location when comparing prices. Add the cost of fitting out an off-plan unit or renovating a resale unit, plus the appropriate transaction costs. Ask for a written inclusions schedule so that a promotional package does not hide a gap in the essentials.

Choose according to your timetable

If you need a home soon, an existing completed unit may be easier to evaluate against that requirement. If you can wait, consider whether an off-plan purchase still suits you under a delayed completion scenario. Avoid assuming you can assign the contract or resell at a profit before transfer.
