Thailand property glut: THB1.3tn unsold stock and 40% mortgage rejections reshape 2026 market

Thailand property in 2026: oversupply, a credit chokehold and price pressure

If you follow the real estate Thailand market, the headline is blunt: more than THB1.3 trillion of unsold housing stock sits on the shelves, and banks are turning down roughly 40% of mortgage applications. That combination is slowing transactions, forcing developers to cut prices and offers, and pushing many homeowners into the market.

This is a market where demand still exists but access to finance is the bottleneck. In this article we break down the numbers, explain how developers and sellers are reacting, flag the riskier locations, and outline what buyers and investors need to check before committing capital.

How big is the oversupply and where did it come from?

The scale of unsold housing in Thailand in 2026 is large by any measure. Prasert Taedullayasatit, honorary president and adviser to the Thai Condominium Association, puts unsold stock at more than THB1.3 trillion, representing over 200,000 units in Bangkok and surrounding provinces. That figure is the starting point when assessing market dynamics.

REIC (Real Estate Information Centre) and industry associations provide further context:

• 72,583 residential units were transferred nationwide in Q1 2026, up 11.2% year-on-year.
• Transfer value in Q1 2026 reached THB187.182 billion, up 3.1% year-on-year.
• In 2025, total transfers of new and second-hand homes were about 310,000 units, compared with nearly 400,000 before the pandemic.
• In 2025, new homes accounted for 38% of transfers and second-hand homes 62%.

The second-hand supply spike is stark. Market listings jumped from 120,000 units in 2024 to 220,000–230,000 units in 2025. That reflects a wave of owners putting homes on the market because of household debt, high living costs and an uneven economy.

For new housing, launches have been pared back. Annual new-home launches have fallen from more than 100,000 to just over 50,000 a year. Nevertheless, new-home stock remains at about 210,000 units, which developers estimate would take four to five years to clear at current absorption rates.

The credit squeeze: why the loan tap is half-closed

Multiple industry voices identify credit access as the single largest constraint on recovery. Soonthorn Sathaporn, president of the Housing Business Association, and a Housing Business Association survey show the loan rejection rate for retail borrowers was around 40% in 2025, and remained at about 40% in the first half of 2026.

That high rejection rate means buyers who are willing to purchase cannot secure funding, so sales stall even when price discounts are offered. Banks cite borrower risks, high household debt and stricter underwriting as reasons for the tight stance. The Bank of Thailand has relaxed some loan-to-value (LTV) rules, but approval behaviour by commercial banks has not loosened at the same speed.

What this means for buyers and investors:

• Lenders remain selective; pre-approval is essential before committing to a purchase.
• Buyers who can pay larger down payments or demonstrate stronger income and credit histories will have an edge.
• Investors relying on bank financing should model scenarios with higher down payments and longer time to secure loans.

Developers’ responses: discounts, fee waivers and promotion wars

Faced with mounting unsold inventory, developers are using aggressive sales tactics. Common strategies include:

• Price discounts averaging 10–30% on new units.
• Waiver of ownership-transfer and mortgage registration fees.
• All-inclusive packages: free furniture, interest subsidies and marketing campaigns such as “live free for four years.”

These measures close the price gap between new and second-hand housing. When a new condominium or detached house is promoted with a heavy discount plus free extras, buyers see immediate value compared with a used unit that offers no warranties. Developers are willing to accept narrower margins to reduce carrying costs and get cash flow moving.

The market effect is clear: when new homes drop in price, second-hand prices follow. Developers’ incentives make new units look more attractive because they include guarantees, modern fittings and often flexible payment terms. That has forced many second-hand sellers to lower their asking prices, and in some cases to reduce prices by nearly 50% if the property requires repairs.

Second-hand market dynamics: large supply and faster turnover

Because prices on the second-hand market are generally lower, turnover there can be faster despite the overall slowdown. Industry estimates suggest second-hand stock would take about two years to clear, compared with four to five years for new homes. Factors driving second-hand market behaviour include:

• Financial pressure on households producing forced listings.
• Buyers’ preference for price and location: second-hand units often have bigger land plots and central locations.
• Sellers’ need to be competitive when developers’ promotions undercut them.

REIC data show second-hand homes comprised about 67% of Q1 2026 ownership transfers, up from around 62% in 2025. That points to sustained demand for used housing at price levels that match buyer budgets.

Oversupply hotspots and property types to avoid

Not all markets are equal. The industry highlights several geographies and segments where oversupply and price declines are concentrated. Exercise caution in these areas:

• Provinces with excessive project completions near Bangkok: Pathum Thani, Nonthaburi, Nakhon Pathom.
• Eastern industrial and commuter provinces: Chon Buri and Chachoengsao.
• Certain condominium corridors where units are mass-produced and prices sit at the lower end: Tiwanon–Nuan Chawee and other locations with units priced THB1–2 million.

Empirical signs of stress include location-level price declines such as an average fall of 8.3% in parts of the Tiwanon–Nuan Chawee corridor within one year.

Three risk categories buyers should evaluate:

1. Physical and disaster risk: flooding, subsidence and other environmental vulnerabilities.
2. Daily-life risk: excessive commuting times, traffic and remoteness from services.
3. Market risk: oversupply and thin resale demand that could make a property hard to sell or lead to falling prices.

How buyers and investors should approach opportunities now

We believe the market offers selective opportunities but requires discipline and deeper checks than before.
