Resale vs New-Build Condo in Thailand: Which Yields More in 2026
By THAI.ESTATE Editorial Team15 min read
Resale condos in Thailand currently deliver net rental yields of 3% to 5% for most foreign investors, while comparable new-build units typically show advertised gross yields of 6% to 8% that compress to 2.5% to 4% net once all costs are counted. The gap is smaller than sales materials suggest, and which option wins depends on your location, budget, and holding period.
As of Q1 2026, resale homes account for 67% of residential transaction volume in Thailand, per Bangkok Post reporting from July 2026. That shift is not a temporary trend. It reflects tighter mortgage approvals, genuine affordability pressure, and buyers choosing completed, income-producing assets over promises. For a foreign investor deciding where to put capital, this structural shift carries real yield and liquidity implications.
This guide works through the full cost chain, contrasts resale against new-build performance, and flags the risks that sales decks routinely omit.
Quick answer
- Resale condos in established tourist zones deliver indicative net yields of 3% to 5% as of 2026, with tenants already in place and no construction wait
- New-build condos advertise gross yields of 6% to 8%, but net figures after management fees, OTA commissions, vacancies, sinking-fund top-ups, and fit-out costs typically fall to 2.5% to 4%
- Resale units carry lower upfront uncertainty: price is known, building quality is visible, and rental history exists
- New-build off-plan carries developer risk, a completion gap of 2 to 4 years with zero income, and the risk of oversupply at handover
- Phuket's beach corridors show up to 70% foreign ownership in high-price zones, per Money and Banking Magazine, July 2026 - resale liquidity in those corridors depends heavily on finding another foreign buyer, since Thai nationals rarely purchase in fully foreign-saturated buildings
- Guaranteed-rental programs attached to new-build projects fix income at a capped rate (commonly 5% to 6% gross for 3 to 5 years) and defer, rather than eliminate, the yield question
Options and scenarios
Buying a resale condo for long-term rental
A resale unit in a mid-market condo building in Phuket or Chiang Mai comes with a visible track record. You can inspect the juristic person (the building's legal management body, equivalent to an owners' corporation) accounts, check the sinking fund balance (the reserve fund collected from owners to cover major repairs), and see actual occupancy data from existing tenants or operators.
For long-term monthly rentals, typical running costs on a resale unit as of 2026 include:
- Common-area (CAM) fees: THB 40 to THB 80 per square metre per month, depending on building grade
- Sinking fund top-ups: often THB 500 to THB 2,000 per year per unit, charged by a vote of owners
- Property management fee if you use an agent: 10% to 15% of monthly rent
- Repairs and cosmetic refreshes: market estimates suggest 1% to 2% of purchase price per year on units over 5 years old
- Vacancy: 1 to 2 months per year is realistic in secondary locations; less in central tourist zones
Working through an example: a resale condo bought at THB 4,000,000 in a Phuket mid-market building, renting at THB 25,000 per month on a 12-month lease.
- Gross annual rent: THB 300,000 (gross yield: 7.5%)
- Management fee (12%): THB 36,000
- CAM fees (60 sqm at THB 60): THB 43,200
- Repairs and maintenance estimate: THB 60,000
- Vacancy provision (1 month): THB 25,000
- Net annual income: approximately THB 135,800
- Net yield: approximately 3.4%
That is less than half the headline gross number. The math does not change much whether the building is old or new: the cost categories are the same.
Buying a new-build off-plan condo
New-build condos in Phuket are being launched at pace. Per Money and Banking Magazine reporting from July 2026, one major Thai developer alone plans to launch 30 new Phuket projects between 2026 and 2029, targeting international buyers in a market where beach-corridor buildings can already be 70% foreign-owned.
The attractions of buying off-plan are real: staged payment schedules (typically 10% to 20% on booking, installments during construction, balance at transfer), modern finishes, and full-building warranty periods. The risks are equally real:
- Construction risk: delays of 6 to 18 months beyond the promised completion date are common in Phuket
- Income gap: no rental income during the construction period, which typically runs 2 to 4 years
- Oversupply at handover: if many units complete simultaneously and all owners try to rent, vacancy rates spike and rents drop
- Fit-out cost: even 'fully furnished' units often require appliances, linen, and extras costing THB 150,000 to THB 400,000 before they are rent-ready
- Resale at handover: some buyers plan to flip at completion. With 67% of 2026 transaction volume already in the resale segment per Bangkok Post, and new supply accelerating, finding a buyer at the original purchase price plus margin is not guaranteed
Short-term vs long-term rental - the hotel licensing constraint
Many buyers of new condos in tourist zones plan to list on short-term rental platforms. This is where a critical legal distinction applies.
Under the Thai Hotel Act, a property offered for stays shorter than 30 days is classified as a hotel. Operating a short-term rental from a standard condominium unit without a hotel license is a violation of that Act. Penalties include fines and the risk of a formal complaint that forces the building to cease short-term letting entirely.
In practice, many buildings in Phuket and Koh Samui do operate informal short-term rental programs because the juristic person chooses not to enforce the restriction. This is legally fragile. A single complaint from a resident or competitor can end the arrangement. When evaluating any unit for short-stay income, you should ask specifically whether the building holds a hotel license or a valid exemption. If it does not, project your returns using monthly-lease income only, because that is the legally defensible scenario.
Buildings that do hold hotel licenses or that are structured as hotel-residential hybrids typically charge higher management fees (30% to 40% of gross revenue under a full hotel-management contract) and require you to join the rental pool, meaning you lose flexibility on owner-use periods.
Guaranteed-rental programs: what the numbers really mean
A common new-build sales tool is the guaranteed-rental program: the developer or an affiliated operator promises a fixed return (typically 5% to 6% gross per year) for a defined period (typically 3 to 5 years). This sounds like certainty. It is not.
The guarantee is funded one of two ways, and neither is as safe as it appears:
- Funded from the purchase price: the developer builds the guarantee cost into the sale price. You are effectively prepaying your own 'guaranteed' income. If the unit is priced 15% above market in exchange for a 5% annual guarantee over 3 years, you have broken even in nominal terms and lost real value.
- Funded from a reserve pool: the developer pools funds from all unit owners to pay guaranteed returns. If occupancy is weak, the pool depletes. After the guarantee period ends, you are left with the actual market yield, which in an oversupplied building may be 2% to 3% net or less.
The guarantee period also typically limits your personal use of the unit to 2 to 4 weeks per year and prohibits you from renting independently. Read the management agreement carefully before committing.
The resale liquidity question in Phuket
Phuket is the clearest case study for the foreign-ownership saturation problem. Per Money and Banking Magazine, July 2026, foreigners own approximately 70% of real estate in Phuket's high-price beach corridors. The Thai Condominium Act allows foreigners to hold a maximum of 49% of the total floor area of any condominium building in freehold title (chanote - a full title deed, the strongest land title in Thailand). In practice, this cap is frequently filled in new popular buildings.
When you buy into a building already near the 49% foreign quota, your exit is structurally limited to other foreign buyers. Thai nationals cannot take your unit under freehold title if the quota is full. This narrows your buyer pool and lengthens your typical selling period. In a resale transaction, this risk already exists and is visible. In a new-build sale, the quota position at completion may be worse than at the time you signed the contract.
High season vs low season: what occupancy really looks like
Sales materials for Phuket and Koh Samui condos frequently quote high-season occupancy rates. The honest picture is seasonal:
- Phuket high season (November to April): indicative short-stay occupancy in managed buildings ranges from 70% to 85%
- Phuket low season (May to October): occupancy falls to 30% to 50% in many areas; rain and reduced flights affect demand materially
- Koh Samui has a less predictable pattern because its rain season differs from the Andaman coast, but low-season dips to 25% to 45% are common per market estimates
Annualised occupancy in a well-managed building often averages 55% to 65%. A sales deck built on 80% occupancy assumptions overstates income by 25% or more before any cost deduction.

Risks and mistakes
Trusting the gross yield number
Gross yield (annual rent divided by purchase price, before any costs) is a marketing figure. It does not reflect what lands in your bank account. Always calculate net yield using the full cost chain: management fees, CAM fees, sinking fund, repairs, vacancy, OTA platform commissions (15% to 20% of booking value on short-stay platforms), and any hotel-management contract share. The difference between gross and net is typically 2 to 4 percentage points.
Ignoring the foreign ownership quota
Confirm the current foreign-quota position in writing before signing any contract, resale or new-build. A building at 47% foreign ownership leaves little room. A building where the developer controls unsold Thai-quota units can manipulate the mix. The quota applies to floor area, not unit count, so large foreign-owned penthouses can fill the quota faster than small units suggest.
Assuming short-stay income without checking the hotel license
Do not project short-stay platform income unless you have seen written evidence of a hotel license or a formal exemption. Operating without one puts your income and your investment at legal risk. If a developer or agent tells you that 'everyone does it and it is fine,' treat that as a warning sign, not reassurance.
Underestimating the construction-period income gap
If you buy off-plan at THB 6,000,000 with a 3-year build period, you lose approximately THB 540,000 to THB 900,000 in rental income that a comparable resale unit would have generated (at 3% to 5% net per year). That gap must be factored into your total return comparison. It often eliminates any price advantage the new-build appeared to offer.
Relying on a guaranteed rental without reading the management contract
The guarantee is only as strong as the counterparty behind it. Developers with thin capitalisation can fail to honour guarantees if the building underperforms. Before buying, request and read the full management agreement, check the developer's other completed projects and their actual rental history, and ask what happens when the guarantee period ends.
Buying in an oversupplied zone without checking pipeline supply
With 30 new Phuket projects planned by one developer alone through 2029, per Money and Banking Magazine, the supply pipeline matters. Research how many units are due to complete within 1 kilometre of your target property over the next 3 years. High pipeline supply in the same rental catchment will pressure rents and occupancy for all owners in that zone.
Misreading the 2026 resale market signal
The fact that resale homes account for 67% of Q1 2026 transaction volume, per Bangkok Post, is not automatically a signal to buy resale. It reflects affordability-led demand from domestic Thai buyers facing mortgage constraints. Foreign buyers operate under different purchase rules (cash or foreign-currency transfer, not mortgage-dependent) and different yield needs. The data point confirms that resale markets are active and liquid, not that every resale unit is a good investment.
FAQ
What net rental yield should a foreign buyer realistically expect from a Thai condo in 2026?
For most locations and unit types, a realistic net yield is 3% to 5% per year as of 2026, after all management costs, vacancies, fees, and repairs. Short-stay units in hotel-licensed buildings can reach the upper end of that range, but carry higher management costs and seasonal risk.
Is a resale condo or a new-build condo better for rental income?
Resale condos typically generate income from day one and carry visible risk (you can inspect the building, review accounts, and see rental history). New-build condos have a 2 to 4 year income gap and face uncertainty at handover. On a full holding-period basis including the income gap, resale often produces better total returns at equivalent price points, though quality new-build in undersupplied locations can justify the wait.
What does the Thai foreign ownership quota mean for resale transactions?
The Thai Condominium Act limits foreign freehold ownership (known as chanote title) to 49% of the total floor area of any condominium building. If that quota is full, you cannot purchase that unit in freehold as a foreigner. In resale transactions, the quota position is knowable today. In new-build, the position at completion may be less certain if developer-held units change hands.
Are guaranteed-rental programs from developers reliable?
Guaranteed-rental programs reduce short-term income uncertainty but do not eliminate risk. The guarantee cap (typically 5% to 6% gross) often reflects a price premium embedded in the unit cost. After the guarantee period (usually 3 to 5 years), you revert to market yield. If the building is in an oversupplied area, that market yield may be lower than the guarantee. Always read the full management contract, not just the headline guarantee rate.
Can I legally list my Thai condo on short-stay rental platforms?
Only if your building holds a hotel license or a valid legal structure for short-term stays. Operating short-stay rentals from a standard condominium without a hotel license violates the Thai Hotel Act. Penalties include fines. Many buildings in tourist zones operate informally, but that arrangement is legally fragile. Base your yield projections on monthly-lease income unless hotel-license status is confirmed in writing.
What costs reduce my gross rental yield to a net figure?
The main cost categories are: property management fees (10% to 15% for long-term, 30% to 40% for hotel-managed short-stay), common-area fees (THB 40 to THB 80 per sqm per month as of 2026 market estimates), sinking fund contributions, repairs and maintenance (1% to 2% of value per year on older units), vacancy provision, and OTA platform commissions (15% to 20% of booking value) for short-stay rentals. Together these typically subtract 2 to 4 percentage points from the gross figure.
How does Phuket's 70% foreign ownership affect my investment decision?
In Phuket beach corridors where foreign ownership reaches approximately 70% of high-price inventory, per Money and Banking Magazine July 2026, your future buyer pool is largely limited to other foreign nationals. Thai buyers cannot take freehold title in a building where the foreign quota is full. This lengthens your average resale timeline and may require a price discount to attract a foreign buyer quickly. Factor this into your exit strategy before committing.
What is the occupancy reality for Phuket condos in low season?
Indicative short-stay occupancy in managed Phuket buildings drops from 70% to 85% in high season (November to April) to 30% to 50% in low season (May to October). Annualised occupancy of 55% to 65% is a realistic planning assumption, not the 80% or higher figures used in some sales projections. Model your income at 60% annual occupancy as a base case.
What is a sinking fund and do I keep paying it after purchase?
A sinking fund is a reserve account held by the juristic person (the building's management body) to cover major future repairs - roof replacement, elevator overhaul, facade work. It is collected from unit owners either as a one-time payment at purchase or as ongoing annual levies voted by the owners' assembly. After purchase, you will likely face periodic top-up votes. Budget for this cost, especially in older resale buildings where major repairs may be approaching.
Does the 2026 shift toward resale transactions signal better liquidity for resale buyers?
Resale transactions at 67% of Q1 2026 volume, per Bangkok Post July 2026, confirm that the resale market is active. For foreign buyers, that activity is concentrated among Thai domestic buyers who are affordability-constrained and often using mortgage finance. Foreign buyers typically transact in cash via foreign-currency transfer. The liquidity signal is positive for the broader market, but your ability to resell will still depend on the specific building, foreign quota position, and local demand at the time of your exit.
