The market value of a resale condo in Thailand cannot be determined from a single listing or an average neighbourhood price. A seller may base the asking price on personal expenses, the original developer price, an expected profit or a neighbouring unit with different characteristics. A buyer therefore needs a comparison based on several genuinely similar properties.
This approach is particularly important when choosing condos for sale in Thailand. Even within the same building, the price per square metre may vary because of unit size, floor level, view, interior condition, ownership structure and the seller’s urgency.
Why the asking price is different from market value
The asking price represents the amount the owner hopes to receive. The final transaction price is shaped by document checks, the condition of the unit, outstanding fees, competing listings and negotiations.
Several values should be considered separately:
- Asking price — the current price shown in the listing.
- Negotiated price — the amount the seller may accept.
- Market value — a range supported by comparable properties.
- Government appraised value — a reference value used during registration and for calculating certain fees.
- Bank appraisal — a valuation that a lender may use when considering a mortgage.
Government and bank valuations can support due diligence, yet they do not replace an analysis of the current market inside the specific condominium.
Which units should be used as comparables
The search should begin inside the same condominium. Nearby developments become useful when the building has too few active listings. Projects in the same area can still differ in age, management, common-area condition, facilities and market reputation.
A useful comparable should match the target unit in the following areas:
- unit type and number of bedrooms;
- size, ideally within a range of around 10–15%;
- similar floor level or floor group;
- window orientation and type of view;
- condition, renovation and furniture package;
- ownership structure and available quota;
- readiness for transfer to a new owner.
It is sensible to collect five to ten listings. After duplicates are removed, the sample may fall to three to seven genuine units. Additional context can be obtained by comparing the property with other completed properties in Thailand of a similar age and market class.
How to remove duplicates and outdated listings
The same condo may be advertised by the owner and several agencies at the same time. Prices, areas, floor numbers and descriptions can vary between advertisements. Counting each placement as a separate unit will distort the result.
Check the following details to identify duplicates:
- interior photographs and balcony views;
- layout and furniture placement;
- unit size and number of bathrooms;
- floor, building and window orientation;
- asking price and previous reductions;
- publication or last update date.
Older advertisements also require confirmation. The unit may have been sold, withdrawn or left online at an outdated price. Ask the agent when availability was last confirmed and whether the owner is currently prepared to negotiate.
How to calculate the base price per square metre
After cleaning the sample, convert every listing into the same measurement. Divide the asking price of each comparable by its unit area. Use the same type of registered or advertised area throughout the calculation.
Price per sq.m. = unit price ÷ unit area.
An arithmetic average can be heavily affected by one unusually expensive or cheap listing. For a small group of units, the median is often more practical. It is the middle value after all prices per square metre have been sorted.
| Illustrative comparable | Area | Price | Price per sq.m. | Comment |
|---|---|---|---|---|
| Unit A | 50 sq.m. | THB 5.70M | THB 114,000 | Mid floor, city view |
| Unit B | 52 sq.m. | THB 5.95M | THB 114,423 | Mid floor, partial sea view |
| Unit C | 49 sq.m. | THB 6.10M | THB 124,490 | High floor, recent renovation |
| Unit D | 51 sq.m. | THB 5.80M | THB 113,725 | Interior requires updating |
In this illustrative example, the base level is close to THB 114,000 per sq.m. A 51 sq.m. condo would therefore have a preliminary value near THB 5.8 million. Individual adjustments must then be applied.
Which characteristics require price adjustments
Price per square metre is a starting point. Two units with the same area may have significantly different market values.
- Unit size. Smaller condos often have a higher price per square metre because the total purchase budget remains more accessible.
- Floor level. A higher floor may command a premium when it provides an open view, better light and less noise.
- View. A direct sea view normally carries more value than a partial, city or internal view.
- Condition. A good renovation reduces the buyer’s immediate expenses. Old finishes, worn appliances and moisture damage reduce value.
- Layout. Corner positions, additional windows, a practical kitchen and a separate bedroom may strengthen demand.
- Furniture. Furniture should be valued according to its current condition and practical use rather than the owner’s original purchase receipts.
- Condominium management. The condition of the façade, lifts, pool, parking and Juristic Office finances affects the value of every unit.
The ownership structure must also be checked. Units available to international buyers under foreign freehold may attract a different buyer pool. The applicable rules are explained in the guide to the foreign ownership quota for Thai condominiums.
How to estimate the negotiation range and liquid price
There is no universal resale discount. The possible reduction depends on the seller’s motivation, time on the market, competing units and the condition of the property.
Possible signs of an inflated asking price include:
- the listing has remained active for many months;
- similar units in the building are offered for less;
- the asking price has already been reduced several times;
- the seller expects to recover the full original cost of furniture and renovation;
- the condo requires further investment;
- the same unit is promoted by many agencies at different prices.
The result should be presented as a range:
- lower boundary — an urgent sale or a unit with weaker characteristics;
- market level — the median of adjusted comparables;
- upper boundary — a strong view, high floor, good layout and excellent condition.
An initial offer may be positioned near the lower end of the supported range. Comparable listings, renovation costs, listing history and transfer expenses provide stronger arguments than a random discount request.
How to calculate the final purchase value
Before negotiations, organise the analysis in one table:
- Collect 8–10 listings in the selected condominium.
- Remove duplicate and unavailable units.
- Select the 3–7 closest comparables.
- Calculate the price per square metre.
- Identify the median value.
- Adjust for floor, view, condition and ownership quota.
- Check common fees, debts and transfer conditions.
- Set a market range and an opening offer.
The final budget includes costs beyond the unit price, such as registration expenses, legal checks, agency fees, renovation, maintenance and possible outstanding balances. These items are covered in the guide to taxes and additional property-buying costs in Thailand.
A valuation cannot predict the final transaction price down to the last baht. Its purpose is to establish a defensible range, reduce the risk of emotional overpayment and support a well-reasoned offer to the seller.
