Off-plan vs resale: buying a new condo in Thailand

What ‘off-plan’ actually means

Off-plan (or pre-construction) means buying from the developer before the building is finished — sometimes years ahead, often off a show suite and a floor plan rather than the actual unit. You usually pay a booking fee, then a contract deposit, then a schedule of instalments through construction, with the balance due at completion and transfer. A resale unit is the opposite: a completed condo you can walk through, with a real view, finished common areas and an existing building management you can assess. The whole off-plan vs resale question comes down to trading certainty for early entry — and how much risk you’re paid to take.

The case for off-plan

There are real reasons buyers go early:

• Launch pricing — the earliest buyers often pay the lowest price in the project’s life.
• Staged payment plans — you spread the cost over the construction period rather than paying in full up front.
• The newest buildings and layouts, and first pick of units, views and floors.
• Potential capital growth between launch and completion — if the market and the project both perform.

That early entry is much of the appeal — but every one of these upsides is conditional on the building actually being delivered as promised. Model the all-in numbers with the purchase-cost calculator before you’re seduced by a launch-day discount.

The real risks of off-plan

You’re paying for something that doesn’t physically exist yet, and that’s the whole risk:

• Completion risk — construction can run late or, with a weaker developer, stall entirely.
• Spec risk — the finished unit can differ from the show suite in finish, size or layout, and facilities can be scaled back.
• Developer risk — in a downturn, an over-stretched developer can hit financial trouble mid-build.
• Market risk — values and rents at completion may not match the launch-day projection.
• Liquidity risk — exiting before transfer can be hard and costly.

None of this makes off-plan a bad idea — strong developers deliver excellent buildings every year. It means the developer’s track record and the contract terms decide everything, and a glossy projection is never a guarantee.

The case for resale

A finished unit removes the guesswork, which is why income-focused buyers often prefer it:

• What you see is what you get — the exact unit, the real view, the finished facilities and the actual building management.
• Income now — you can often move in or rent it out immediately, rather than waiting years.
• Provable performance — you can assess the building’s real rental history and condition before committing, and sanity-check the yield against reality.
• Confirmable quota — you can verify the unit’s foreign-freehold status before you buy (see below).

The trade-off is that you typically pay the going market price rather than a launch discount, and the building isn’t brand new. For many investors that certainty is worth it. Compare the long-run maths with the rent-vs-buy and cap-rate tools.

The foreign-quota trap at handover

This one specifically catches off-plan buyers. Thai law caps foreign ownership of a condo building at 49% of the saleable floor area, allocated unit by unit. With a resale unit you can confirm it sits within the foreign (freehold) quota before you commit. With off-plan, foreign demand in a popular project can fill the 49% before your unit transfers — so a foreigner who paid instalments for years can reach handover to find no freehold quota left for that unit, leaving leasehold or other workarounds instead of the freehold they expected.

The protection is simple: get written confirmation of your place in the foreign freehold quota as part of the off-plan contract, and verify it again before transfer. Our foreign-ownership guide explains the quota and the FET (money-from-abroad) rule in full.

How to vet a developer

If you go off-plan, the developer is the investment. Do the due diligence:

• Track record — did past projects finish on time and to the promised quality, and how have they held value and been managed since?
• Financial standing — the company’s credibility and ability to fund the build to completion.
• Permits & approvals — that the project has its proper permits, including environmental clearance where required.
• Contract protections — what the contract gives you on delays, defaults and your deposit.
• Independent legal review — a licensed lawyer who is yours, not the developer’s, reads the contract before you sign.

The same disciplined due diligence applies to a resale purchase — our buying-process guide walks the full transaction. Browse current projects on new developments.

Match it to your strategy

The right answer follows your goal, not the marketing:

• Chasing capital growth, comfortable with risk, long horizon? Off-plan from a proven developer can fit — you’re betting on delivery and appreciation.
• Want predictable income now? Resale tends to win — immediate, provable yield with the unit and the quota confirmed.
• Risk-averse or first time in the market? The certainty of resale is usually the safer first move.
