Second-hand condos in Bangkok with resale units and a way to compare prices against the market

Key Highlights

• A second-hand condo is any unit whose title has already been transferred to a private owner once, so the seller is an individual rather than a developer
• Thailand's Real Estate Information Center reported 72,583 residential transfers nationwide in Q1 of 2026, and 67 percent of them were second-hand homes
• In the segment priced up to 7 million baht, the average value per transferred second-hand unit works out to roughly 1.68 million baht against roughly 2.81 million baht for new units
• National averages describe direction, not your unit. The number that decides a deal is price per square meter set against the same building and the same street
• Add the cost of refurbishment to the resale price before you conclude it is the better value, because that line can absorb close to a third of the apparent gap
• For foreign buyers the building's 49 percent freehold quota matters more than the age of the unit, and older buildings are likelier to have used theirs up

What counts as a second-hand condo in Thailand?

A second-hand condo is a unit that has already been registered to a private owner at the Land Department and is now back on the market. It does not automatically mean an old unit. A condo handed over last year and never lived in is still legally a resale. What actually changes is who sits across the table from you. Instead of a developer's sales office with a fixed price list, you are negotiating with an individual owner who has their own timeline and their own reasons for selling

That difference works in your favour more often than not. Individual sellers price against what they paid and what they still owe, so the range within a single building can be wide. It also means nobody is bundling in a furniture package or a transfer-fee promotion, and nobody will fix a problem for you after handover. Everything you accept on viewing day is what you own

The market is larger than most buyers assume. In its Q4 2025 report on the nationwide second-hand housing market, the Real Estate Information Center counted 226,278 units advertised for sale, up 29.8 percent year on year, worth 1,200,372 million baht, up 54.7 percent. Condominiums accounted for 70,611 of those units, or 31.2 percent, behind detached houses at 90,502 units or 40 percent and ahead of townhouses at 57,257 units or 25.3 percent. Bangkok alone carried 31.4 percent of the units and 60.7 percent of the value

How do you search for second-hand condos on PropertyScout?

The Bangkok condos-for-sale page on PropertyScout covers both developer stock and owner resales. Three filters, applied in this order, get you to a shortlist you can actually work through

Set budget as a range, then location, then floor area

Use a range rather than a ceiling. Units listed 5 to 10 percent above your number often settle inside it, because resale pricing is set by one person rather than a pricing committee. Pick location by the stations and streets you genuinely use on a weekday, not by the neighbourhood you have heard of. Then filter by square meters rather than bedroom count, since a 45 square meter two-bedroom and a 60 square meter two-bedroom are different homes

Treat building age and unit condition as two separate questions

A well-run building at 25 years old that has already replaced its lifts and water pumps is a safer purchase than a 12-year-old building that has never had a major overhaul and is due for one. A freshly renovated unit inside a struggling building means paying for what you can see while inheriting the risk of what you cannot. Keep the two questions apart from the moment you start filtering

Read the listing status tags

Listings on PropertyScout are de-duplicated and confirmed with the owner, and carry status tags such as move-in ready and confirmed available. Those tags cut the time lost on units that sold weeks ago but never came down, which is the single most common frustration in resale search. Prices and availability still change without notice, so confirm with the agent before you travel to a viewing

How much less do second-hand condos cost than new ones?

What the national figures do and do not tell you

In the Real Estate Information Center's Q1 2026 report, the segment priced up to 7 million baht recorded 69,447 transfers worth 141,242 million baht. Of that, second-hand homes made up 47,457 units worth 79,526 million baht, and new homes 21,990 units worth 61,716 million baht. Dividing value by units gives roughly 1.68 million baht per second-hand unit against roughly 2.81 million baht per new unit, a gap of about 40 percent

That 40 percent is calculated from the source data rather than published by the agency as a price gap, and it carries three limits worth stating plainly. It blends every property type rather than isolating condos. It is a price per unit rather than per square meter, which is the only unit that compares. And it reflects the mix of properties that happened to transfer in one quarter, not what a single unit would fetch in two different states

A three-line method for measuring the gap in the area you care about

Rather than wait for someone to publish an area-by-area table, calculate it yourself. Ten minutes per area, and the answer describes the unit you are actually about to buy

• Line one. Find the price per square meter of new stock in that area by dividing the asking price of the nearest new project by the usable area of a comparable unit
• Line two. Find the price per square meter of the resale unit by dividing its asking price by the usable area stated on the condominium title deed, not the marketing brochure
• Line three. Divide the difference by the new figure and multiply by 100. That percentage is a comparison you can defend

Repeat it across at least three resale units in the same area and see where your unit sits in the group. A unit priced far below the cluster usually has a reason that has not made it into the listing, such as a west-facing bedroom, a blocked view, or outstanding common area fees

A worked example using illustrative figures

Suppose a 35 square meter unit in a new project asks 4.2 million baht, which is 120,000 baht per square meter. A same-sized resale unit in the building next door asks 3.15 million baht, which is 90,000 baht per square meter. The gap looks like 25 percent

Now suppose the resale unit needs new air conditioning, repainting and new bathroom fittings, totalling 300,000 baht. The real cost becomes 3.45 million baht, or 98,571 baht per square meter, and the gap falls to 17.9 percent. Refurbishment absorbed close to a third of what you saw at first glance. This is why that line belongs in the calculation before you decide which unit represents better value

Second-hand condos listed right now

The listings on this page come from the de-duplicated PropertyScout database. Each card shows the asking price, usable area, floor, and walking distance to the nearest station. Where enough data exists for the building, a tag shows how the asking price sits against the average for that same building. That tag is a data comparison, not a valuation and not a guarantee of price

What should you inspect before placing a deposit?

Title documents and the debt-free certificate

Ask for a copy of the condominium title deed and the seller's identification, then check that the registered owner is the person you have been dealing with. If the unit has co-owners, you need consent from all of them before any deposit changes hands. The other document that decides whether the deal can close is the debt-free certificate issued by the juristic person, confirming there are no outstanding common area fees. The Land Department requires it before registering a transfer. Where arrears exist, agree in writing who settles them and when

Condition and building systems that photographs never show

On viewing day, open every tap at once to test water pressure. Run the air conditioning for at least fifteen minutes and listen for noise and watch for drips. Look for staining on the ceiling beneath bathrooms and balconies, where leaks appear first. Bring your own plug tester and check every socket. The detail people forget is the balcony door frame. If it sticks, the building has settled or the frame has warped, and that is rarely a one-time repair

Costs buyers routinely leave out of the budget

Beyond the purchase price there is the transfer fee at the Land Department, the mortgage registration fee if you finance, the bank's valuation fee, fire insurance, a sinking fund contribution in some buildings, and advance common area fees collected at transfer. On the seller's side there is withholding tax and either specific business tax or stamp duty, at rates that depend on holding period and house registration status. Agree in writing who pays which line, and confirm current rates with the Land Department and the Revenue Department before signing

What do foreign buyers need to settle first?

Confirm the building's foreign ownership quota before anything else

Under the Condominium Act, foreign nationals may hold freehold title to condominium units up to a capped share of the total unit floor area in each building, commonly cited as 49 percent. That cap belongs to the building, not to the age of the unit, so it applies to resales exactly as it applies to new stock. Older buildings have had longer to use theirs up. Where the quota is full, the remaining route is leasehold, which is a different asset with a different resale profile. Ask the juristic person for the quota position in writing before placing a deposit and treat anything verbal as unconfirmed

Government fee reductions may not reach you

The reduced transfer and mortgage registration fees introduced to support the market have been framed around Thai individual buyers purchasing for their own residence. Foreign buyers should assume the standard rate applies and budget accordingly. On a 5 million baht unit the difference between 2 percent and a token rate is around 100,000 baht, which is not a rounding error. Confirm your own position with the Land Department, since these measures are amended from time to time

Financing and how the funds arrive

Mortgage options from Thai banks are narrower for non-residents than for Thai buyers, so most foreign purchases are funded from abroad. Funds intended for a foreign freehold purchase generally need to be remitted into Thailand in foreign currency and converted to baht locally, with documentation from the receiving bank, because the Land Department requires evidence of that when registering the transfer to a foreign national. Start the paperwork before you agree a transfer date. It is the most common source of delay in these transactions

Which second-hand condos offer the best value?

Building age against the price you should pay

There is no age at which a condo becomes too old to buy. What matters is the reserve fund and the maintenance work queued behind it. A building that has already replaced its lifts is past the expense that catches new owners by surprise. A building that has not is carrying it into your ownership

Three signals that describe a building better than its age

How do you search by area and by station?

Resale supply does not sit where new launches sit. The densest resale inventory is in areas where condominiums were completed ten or more years ago, which are also the areas where the shops, clinics and schools around the building have had time to settle in. Search by district and by station together rather than committing to one district early

Frequently asked questions about second-hand condos

Where can I find good-priced second-hand condos in Bangkok

Start with the PropertyScout condos-for-sale hub for Bangkok, which covers both new and resale stock. It is free for buyers, with zero commission on your side. Filter by budget and location first, then compare each unit's price per square meter against the average for its own building. A good price is one that sits below the building average for a reason you can live with, not the lowest number on the results page

How much less do second-hand condos cost than new ones

Using Q1 2026 figures from the Real Estate Information Center for homes priced up to 7 million baht, the average value per transferred second-hand unit works out to roughly 1.68 million baht against roughly 2.81 million baht for new units, a gap of about 40 percent. That figure is calculated from the published source data, blends all property types, and is measured per unit rather than per square meter, so treat it as direction rather than an answer about your unit. For that, use the three-line method above

Can foreigners buy a second-hand condo in Thailand

Yes, subject to the conditions in the Condominium Act, including the cap on the share of a building's unit floor area that foreign nationals may hold in freehold. Because that cap sits with the building rather than the unit, it applies to resales in the same way it applies to new projects, and long-established buildings are likelier to have filled it. Ask the juristic person for written confirmation of the quota position before you place a deposit. This is general information and not legal advice

Can I get a Thai mortgage on a resale unit

Thai banks lend on resale condominium units routinely for Thai buyers, with one important difference from new stock. The bank commissions its own valuation, and the approved amount follows that valuation rather than the price you agreed with the seller. Where the valuation lands lower, the shortfall is cash you need to have ready. Options for non-residents are considerably narrower. Terms and rates vary by bank and change over time, so check directly with the lender

At what age is a condo too old to buy

There is no single age. Look at three things instead. How much of the common area fee the building actually collects, how much sits in the sinking fund against the repairs already scheduled, and whether the core systems such as lifts, pumps and waterproofing have been renewed. A building that answers those well is comfortable at 20 years and still resells. One that cannot is carrying a future levy at 10

Summary

The resale market is where most completed transactions in Thailand actually happen, and it reaches areas where new launches no longer do. What separates a good deal from an ordinary one is never the headline price. It is the price per square meter after refurbishment costs are added, measured against the same building and the same street, together with the financial health of the juristic person you are about to become a co-owner alongside

A practical next step is to pick one or two areas you would genuinely live in, run the three-line calculation across at least three resale units there, and request the title documents and the debt-free certificate ahead of any viewing. For foreign buyers, request the quota position in the same message. Those two documents remove most problem units before you spend a Saturday travelling to see them
