New Build vs Resale Condo Thailand 2026: Which Is Better?

The short answer: new build or resale

Resale wins on price, on immediate income, and on removed completion risk. A well-maintained 5-10 year old condo typically trades at a 10-30% discount to the equivalent new-build launch in the same building or micro-location. New build wins on developer warranty, off-plan discount if bought early enough in the launch cycle (10-30% below completion price), choice of unit, and the ability to stage payments over the 24-36 month construction period.

For a yield-focused foreign buyer who wants income from day one and the cleanest due diligence path, resale is the lower-risk choice. For a buyer willing to underwrite 24-36 month construction risk for a 10-30% off-plan discount, a staged payment schedule, and a brand-new unit with 1-5 year warranty, new build (off-plan primary) is the stronger financial play. For a buyer who wants a new unit without construction risk, ready-to-move-in new build (completed primary stock) sits in the middle: premium to resale, discount to peak off-plan, zero wait.

This comparison is built on CBRE Thailand 2026, Cushman & Wakefield Q1 2026, Savills Thailand 2026, Knight Frank Thailand 2026, the Consumer Protection Board 2015 standard off-plan contract, Condominium Act B.E. 2522 Section 19, REIC 2025 foreign demand data, and GlobalPropertyGuide Q1 2026 yields.

The price differential explained

New-build Thai condos typically launch at a 10-30% discount to the projected completion price, close to current market at the midpoint of construction, and sell final units at or above market at handover. Resale condos in the same area and specification trade at a 10-30% discount to new-build equivalent on 5-10 year old stock, widening to 30-50% on 10-20 year old stock.

New-build off-plan discount

The off-plan discount exists because the buyer takes completion risk and provides interest-free construction financing via staged payment. A typical Thai off-plan schedule: reservation 100,000-300,000 THB; contract deposit 10-20% within 30-60 days; construction instalments 10-25% spread over 24-36 months; final payment 60-75% at transfer. First-wave buyers at “Friends and Family” or “VIP Launch” pricing achieve 20-30% discounts to completion price; mid-construction buyers 5-15%; handover buyers pay full market.

Resale discount to new build

A well-maintained 5-10 year old condo typically trades at a 10-30% discount to a new launch at the same specification, reflecting age depreciation, inherited sinking-fund and juristic-person position, seller motivation, and absent developer warranty. On 10-20 year old stock the discount widens to 30-50%; 25+ year buildings face structural maintenance concerns that can drag pricing further.

Building age	Typical discount vs equivalent new-build	8M THB new-build equivalent
0-2 years (just completed)	0-10%	7.2-8.0M THB
3-5 years	5-15%	6.8-7.6M THB
5-10 years	10-30%	5.6-7.2M THB
10-15 years	20-40%	4.8-6.4M THB
15-20 years	30-50%	4.0-5.6M THB
20+ years	40-60%+	3.2-4.8M THB

Foreign quota: new vs resale

On new-build launches, the 49% foreign saleable-area quota under Condominium Act Section 19 is fresh and tracked by the developer’s sales office. On resale, foreign quota is inherited: a unit sold by a foreign seller typically transfers within quota to a new foreign buyer; a unit sold by a Thai seller may or may not fit within the remaining foreign quota depending on current building status.

New-build launches designate the 49% foreign saleable-area pool at project registration; buyers see real-time quota status at the sales office. In high-demand cities (Pattaya, Phuket, Samui), quota often fills within 12-24 months of launch, leaving Thai-only inventory for later buyers. See the foreign quota 49% rule guide.

Condominium Act Section 19 requires the juristic person to maintain foreign ownership below 49% of saleable area at all times. On resale, foreign-to-foreign transfers retain the unit’s quota position; Thai-to-foreign transfers require the building to have quota available at transfer; foreign-to-Thai transfers open foreign quota by the square-metreage of the transferred unit. Before depositing on a resale unit, the buyer’s lawyer obtains a written foreign-quota confirmation from the juristic person as a standard 3-5 day process.

Warranty and delivery risk

New build carries a 1-year workmanship warranty and 5-year structural warranty from the developer, standard in Thai off-plan practice and codified by the OCPB 2015 standard contract. Resale carries no developer warranty; the buyer accepts the unit and building in their current condition.

Under the 2015 Office of the Consumer Protection Board standard condominium off-plan sales contract, the 1-year warranty covers workmanship defects (finishes, plumbing fittings, electrical, doors, windows, common-area installations) and the 5-year warranty covers structural elements (load-bearing, waterproofing, major MEP systems). The OCPB contract also mandates deposit protection, construction progress disclosure, buyer’s right to cancel with refund if delay exceeds the stipulated grace period (typically 365 days), and standardised liquidated-damages clauses.

A well-maintained 5-10 year old condo typically carries lower technical risk than an off-plan unit because the actual condition is observable, while an off-plan unit is a contractual promise of future condition. Weighing warranty against observable condition is the core new-vs-resale trade-off.

Yield comparison

Resale condos and new-build ready condos deliver similar current rental yields. Off-plan new-build yields are zero during construction but compound from completion; the off-plan capital gain over the build period effectively front-loads the return.

Strategy	New Build Off-Plan	New Build Ready	Resale 5-10 yr
Current rental yield (gross)	0% during build	5.0-7.0%	5.5-7.5%
Rental yield at completion	5.5-7.5%	5.0-7.0%	5.5-7.5%
Effective total return over 3 yr	10-30% price gain + compound yield post-completion	15-25%	18-28%
Net yield (after expenses)	3.8-5.2% post-completion	3.5-4.8%	3.8-5.2%
Vacancy risk	Low at completion (new product)	Moderate (unfamiliar building)	Low (established track record)

Sources: GlobalPropertyGuide Q1 2026, CBRE Thailand 2026, Savills Thailand 2026.

Why resale often wins on yield. Lower entry price against similar rent produces the yield premium. A 6M THB resale renting at 35,000 THB/month yields 7.0% gross; an 8M THB new-build equivalent renting at 38,000 THB/month yields 5.7% gross.

Why off-plan can win on total return. A 20% launch-to-completion gain on a 6M THB unit is 1.2M THB over 30 months, equivalent to 8% annualised before yield. Add 5 months of post-completion yield at 6% and total return over the three-year period compounds attractively. The caveat is delivery risk: a delayed or cancelled project absorbs the theoretical gain.

Due diligence focus

The due diligence focus differs by category. New build centres on developer and contract; resale centres on unit, building, and juristic person.

DD priority	New build off-plan	Resale
Primary focus	Developer financials and track record	Unit and building physical condition
Title	Developer holds freehold or long-lease before launch	Chanote / condo title search, quota confirmation
Contract	OCPB 2015 standard form with grace period	Standard SPA with seller; verify seller status
Permits	EIA approval, construction permit	Permits already issued, verify CO
Financial	Payment schedule, escrow/protection structure	Juristic person financials (3 yr), sinking fund
Physical	Specification schedule (materials, appliances, finishes)	Unit inspection + common-area inspection
Future risk	Delivery date and delay clauses	Major works pipeline (next 5 years)
Other	Developer liquidity, pipeline risk	Common-fee arrears, mortgage discharge

Pros and cons at a glance

New build off-plan

Pros: 10-30% discount to completion market; interest-free staged payment over 24-36 months; first choice of unit, view, floor; brand-new condition with warranty; transfer fees often subsidised by developer; potential launch-to-completion capital gain.

Cons: construction delivery risk (delay or default); no income during build; currency exposure over 24-36 months; cannot inspect finished product; developer financial stress cases (rare in tier-1, occasional in tier-3).

New build ready

Pros: zero delivery risk; brand-new condition with warranty; immediate occupancy and rental capability; transparent pricing against observable comps.

Cons: premium to off-plan entry pricing; remaining units often less desirable; limited negotiation leverage.

Resale

Pros: 10-30% discount to equivalent new-build pricing; observable unit and building condition; immediate rental income; established juristic-person track record; direct seller negotiation; known neighbour and building culture.

Cons: no developer warranty (accept-as-is); inherited sinking fund level, which may be deficient; potential major-works cost exposure within first 5 years; dated finishes and some mechanical wear; foreign quota must be confirmed before deposit on Thai-seller units; higher transaction cost (SBT 3.3% if seller held <5 years).

Who wins by buyer profile

Profile maps to the winning choice.

Yield-focused investor, immediate income required

Winner: Resale. Lower entry, observable condition, immediate rental income. Target 5-10 year old buildings in Jomtien, Pratumnak, Sukhumvit mid-Soi, or established Phuket areas.

Capital-gain investor with 30-month horizon

Winner: New build off-plan if early in launch. First-wave buyers in tier-1 Pattaya or Bangkok launches can clear 15-25% capital gain by handover. Select reputable developers (Sansiri, AP Thailand, SC Asset, Origin, Ananda, Raimon Land).

First-time foreign buyer, prioritising safety

Winner: Resale. Observable condition plus straightforward transfer reduces complexity. No 24-36 month wait.

Lifestyle buyer wanting brand-new with no wait

Winner: New build ready. Zero delivery risk, brand-new, available today. Accept modest premium over off-plan entry.

Retiree buying primary residence

Winner: Resale in most cases. Move in now, no wait, observable building quality, established neighbour community.

Tax and transaction cost comparison

New-build developer-led transactions often carry promotional absorption of transfer fees and stamp duty; resale transactions typically split costs buyer-seller by convention, producing higher out-of-pocket on the buy side for resale.

Cost item	New build (promotional)	Resale (typical split)
Transfer fee (2%)	Often absorbed by developer	Typically split 50/50
Stamp duty (0.5%)	Often absorbed	Paid by seller
Specific Business Tax (3.3%)	N/A (not applicable to original sale from developer)	Paid by seller if held <5 yr
Withholding tax	N/A (corporate WHT on developer)	Paid by seller
Foreign remittance documentation	Buyer responsibility	Buyer responsibility
Conveyancing legal fee	30-50k THB	30-60k THB (more complex DD)

See the condo transfer fees guide and the Thailand property taxes guide.

Frequently asked questions

Is it cheaper to buy off-plan in Thailand?

Typically yes. First-wave off-plan buyers achieve 10-30% discounts to completion market pricing. The discount narrows to 5-15% mid-construction and disappears at handover. It is the buyer’s compensation for taking 24-36 months of construction and delivery risk.

What warranty comes with a new-build Thai condo?

Thai off-plan condo contracts under the 2015 OCPB standard form provide 1-year workmanship warranty and 5-year structural warranty. Workmanship covers finishes, plumbing, electrical, doors, windows. Structural covers load-bearing elements, waterproofing, major MEP systems.

Does foreign quota carry over on resale?

A foreign-owned unit sold to a new foreign buyer retains its place in the 49% quota. A Thai-owned unit being sold to a foreign buyer requires the building to have foreign quota available at transfer. Always confirm foreign quota in writing with the condominium juristic person before depositing on a resale unit.

How much of a discount do 10-year old condos trade at vs new build?

Typically 20-40% below equivalent new-build launch pricing in the same area and spec class. A 10M THB new-build equivalent 2-bedroom in Jomtien compares to a 6-8M THB well-maintained 10-year old equivalent nearby. Exact discount depends on building maintenance, location, view, and foreign-quota availability.

What is the main risk of off-plan?

Construction delivery risk: the developer may delay beyond the grace period, default, or deliver lower specification than contracted. The OCPB 2015 standard contract gives buyers cancellation and refund rights, but recovery is slow if the developer is financially stressed. Mitigate by selecting tier-1 developers with 10+ year track records.

Do resale condos need more maintenance?

Older stock carries accumulated wear in the unit and common areas. Budget 3-8% of purchase price for initial unit refresh on 10+ year old stock, and verify the building sinking fund is adequately provisioned for upcoming major works. A strong juristic person with well-provisioned sinking fund is the single biggest indicator of ongoing maintenance cost risk.

Which has better resale liquidity when I exit?

Mid-market 5-10 year old buildings with strong management sell in 2-6 months. Off-plan resale before completion is thin; most buyers hold to completion. New-build ready resale in the first 2-3 years sells quickly if the building has reputation, slower in less differentiated stock.
