Investing in Thai property attracts a great many buyers every year, drawn by the sunshine and the attractive opportunities of the local market. Between the authentic charm of older stock and the modern comfort of new build, making an informed choice is not always straightforward. Property prices, differences in service charges and purchase costs, the particularities of property taxation and rental yield potential: there are plenty of criteria to examine carefully before entering this fast-changing market. Which type of property should you favour in 2025 to get the best terms? Here is a full analysis to guide your decision.
Comparing prices between new build and older property in Thailand
In Thailand, the price gap between new build and older property can be marked depending on the region or city you target. The price per square metre varies noticeably, influenced by location, the general condition of the property and its appeal to tourists. Many buyers hesitate between a modern condo built to international standards and an older apartment offering more space but also more issues to manage.
In major cities such as Bangkok, Phuket or Chiang Mai, new projects appeal for their security, their recent facilities and their potential for rapid appreciation. Conversely, in some smaller seaside resorts, older property retains all its appeal thanks to a lower initial acquisition cost. It is therefore essential to compare the advantages of each option precisely, according to the area targeted and the type of project envisaged.
What are the average prices per square metre?
The price per square metre reveals notable gaps between new and older stock. In 2025, a new-build villa in a sought-after Bangkok district is often listed at around THB 120,000/m², while an older apartment in a conventional building ranges between THB 80,000 and THB 100,000/m². In Phuket or Samui the gap is sometimes even wider: a new condo near the beach frequently exceeds THB 140,000/m², whereas older stock hovers around THB 90,000/m².
Older property therefore lets you target more generous floor areas for the same budget, even if renovation costs can quickly erode that initial advantage. Here is a simplified summary table:
| City/region | Price/m² – new build (THB) | Price/m² – older (THB) |
|---|---|---|
| Bangkok | 120,000 | 85,000 |
| Phuket | 140,000 | 90,000 |
| Chiang Mai | 100,000 | 70,000 |
This variation explains why the new versus older question remains essential for any buyer looking to optimise their property investment in Thailand. Our comparison of off-plan and resale condos goes into the trade-off in more depth.
Differences by property type
New-build villas appeal for their contemporary design and their private pools, but their high price sometimes puts them out of reach depending on the budget. Older apartments, especially in city centres, remain sought after for their character, their structural solidity and their strategic position.
In the condo segment, new build is particularly attractive to foreign investors thanks to its simplified management and integrated services. Recent complexes often include a gym, a pool and 24/7 security, which justifies a significant price premium over older stock, especially for buyers targeting immediate or seasonal rental yield.
Which service charges and purchase costs differ between new and older property?
Buying a property always involves additional costs, but these differ according to the age of the home you choose. In Thailand, the list of service charges and purchase costs includes not only the standard items (conveyancing, transfer of ownership) but also various fees specific to each type of property.
For new build, developers sometimes offer discounts on certain fees, with "turnkey" packages designed to appeal to international buyers. Older property, for its part, can hold budget surprises linked to the general condition of the building, to potential upgrade works or to bringing it up to modern standards. Our breakdown of purchase costs in Thailand lists each line item.
Running charges and maintenance
In a new development, monthly charges generally include extensive services: maintenance of common areas, sports facilities, gardening or a concierge. The bill depends on the size of the project but averages between THB 50 and THB 80 per m² per month. This model reassures owners, since every service is clearly defined from the outset.
Conversely, owning an older apartment or an older villa in Thailand sometimes means lower charges at first sight, but exposes you to more frequent renovation costs. You need to anticipate replacing ageing installations, repairing cracks or modernising electrical systems, all of which can push up the overall bill after purchase.
Purchase costs and taxes on the transaction
At the point of purchase, new build generally involves tax payments structured according to the deal negotiated with the developer, who sometimes covers part of the transfer fee. For older property, these costs are negotiated directly between seller and buyer, with some room for manoeuvre depending on the situation.
As a rule, the transfer fee represents about 2% of the property price, on top of which come taxes and duties that vary from case to case; the scales are published by the Land Department. Nor should you overlook agency or advisory fees, which apply whatever type of property you choose.
Property taxation and property taxes in Thailand in 2025
Property taxation in Thailand changes regularly, seeking to balance national budget needs against the country's appeal to foreign investors. Getting to grips with the main property taxes and the regimes that apply lets you plan a profitable and secure investment, whether you intend to live in the property or to target rental income.
Whether you choose a new or older property, the tax regime is broadly the same at national level. A few specific points nonetheless deserve attention, particularly for strategies built around letting or a quick resale.
Local taxes and property taxes
Since the 2020 tax reform, an annual land and building tax applies to all residential properties, calculated on the assessed value of the asset. This charge, which varies according to use (main residence or letting), starts at a low rate but rises when the property generates regular rental income.
Here is a summary of the rates applicable in 2025 by property category:
| Property type | Tax rate (%) | Use |
|---|---|---|
| Villa / detached house | 0.02 – 0.10 | Residential / investment |
| Apartment / condo | 0.02 – 0.15 | Short- or long-term letting |
This tax is settled every year, so keeping track of it is essential if you want to avoid unpleasant surprises. The differences between cities and regions mainly concern the official method used to assess the value of the property.
Tax on capital gains and rental income
On resale, Thailand levies a capital gains tax on property, calculated according to how long the asset was held and the status of the seller. For rental investments, declaring the rent received triggers an annual tax generally between 5% and 15% depending on the amount declared, which directly affects the expected rental yield. Current scales are published by the Revenue Department.
Whether you are a first-time owner, an experienced investor or a temporary resident, it is crucial to adjust your forecasts to your strategy. That makes the choice of property type, geographical area and forward tax planning decisive in maximising your return on investment.
- Annual verification of the mandatory land and building tax.
- Rigorous declaration of rental income to avoid penalties later.
- Negotiation of transfer fees from the very start of the transaction.
- Comparison of the total cost (purchase price, charges, tax) before committing to anything.
Frequently asked questions about new versus older property in Thailand for 2025
What are the main advantages of buying new rather than older property in Thailand?
New-build properties guarantee modern installations, better energy efficiency and a set of recently built communal services. What is more, maintenance charges stay low during the first years of occupancy. In return, the purchase price is generally higher than for older stock, but the risk of unexpected problems in day-to-day management is greatly reduced.
- Optimal security and comfort
- Immediate compliance with international standards
- Little major work to plan for over several years
How do charges vary according to the type of property chosen?
In new-build property, charges often include access to facilities (gym, pool, security). They average between THB 50 and THB 80 per m² per month. For older property, the charges themselves look lower at first glance, but you have to factor in routine maintenance and any major renovation, which can become substantial over the medium term.
- Routine maintenance
- Occasional renovation
- Optional communal services depending on the building's management
Are there major tax differences between buying new and older property?
The rules of Thai property taxation draw no major distinction between new and older property when it comes to the land and building tax or tax on rental income. At the point of purchase, however, the developer of a new-build property will sometimes agree to cover part of the transfer fee, which is generally not the case in a private treaty sale of older stock.
| Property type | Share typically covered |
|---|---|
| New build | Part of the transfer fee, by the developer |
| Older | Fees shared or borne entirely by buyer or seller |
What factors influence rental yield in Thailand in 2025?
Rental yield depends mainly on the type of property chosen (villa, condo, apartment), on its location (close to the beaches or to the city centre) and on its general condition. New properties often allow you to ask for higher rents in tourist areas, but they require a larger initial investment — Phuket is a good illustration. Older property can offer a higher apparent return after renovation, provided you keep control of maintenance charges and the tax that applies.
- Geographical position (city, region, access)
- General condition of the home
- Type of tenant targeted (tourist, expatriate resident, long-term family)
- Structure of charges and local taxation
