Affordable-housing sales in Thailand collapse: what buyers and investors must know

A sudden collapse in affordable housing sales — and why it matters

The real estate Thailand market for homes priced at no more than THB3 million has recorded its steepest fall in a decade, and the consequences are already visible in Bangkok and surrounding provinces. Demand has not vanished; lending has. With mortgage rejections soaring and household debt high, many first-time buyers are simply shut out of ownership.

In our analysis, this is more than a cyclical slowdown. It is a structural squeeze on the segment that once anchored local demand. The numbers are stark and precise: presale value in the segment plunged 52% year-on-year in 2024 to THB54.377 billion, and the downtrend continued into 2025.

Key figures and the current state of play

The data leave little room for optimism about quick fixes.

• Peak presale value (2018): THB147.965 billion.
• 2024 presale value (sub-THB3m segment): THB54.377 billion — down 52% YoY.
• First nine months of 2025 presales: about THB33.889 billion — down roughly 20% from THB42.4 billion for the same period in 2024.
• Share of the sub-THB3m segment in the market: fell from 36% in 2014 to about 21% in 2024.
• Mortgage rejection rates: persistently above 39–40% according to a third-quarter 2025 survey by the Thai Housing Business Association.
• Thailand condo launches in 2025: only 40 projects totaling 17,110 units — the lowest annual supply in 17 years.
• Investment value for condo launches in 2025: THB70.368 billion, down from typical annual levels above THB100 billion.

These figures come from industry bodies and market research firms. They show a housing sector squeezed at both ends: demand constrained by financing, supply curtailed by developer caution.

Why lending rules and household debt are driving the slump

The story is simple and painful. Banks tightened lending criteria after years of rising household leverage and amid weak economic growth around 1–2%. That left large swathes of the population unable to meet rigid income proofs and valuation tests.

From the Thai Housing Business Association survey of 17 developer members:

• More than 70% of loan-application problems are linked to strict bank criteria and complex documentation.
• The most common causes of rejection are: incomes falling short of bank requirements and appraised values lower than selling prices — together making up over 60% of reasons cited.
• Self-employed and gig-economy workers are particularly affected because banks often reject alternative income evidence.

High rejection rates do not just hit buyers. Developers face a knock-on effect: fewer confirmed sales, longer marketing periods, and an incentive to delay or scrap new launches. That is why Colliers Thailand records only 40 new condo projects in 2025, producing 17,110 units — the lowest in 17 years.

What developers and market analysts are proposing

Developers are pressing for policy and operational changes to restore the first-home pathway. Their recommendations include:

• Easing lending criteria and recognising new forms of income for the self-employed and online sellers.
• Special low-interest loans for first homes or for homes priced under THB3 million.
• Tax relief on mortgage interest and on down payments to reduce upfront costs.
• Simplified documentation and faster approval processes by both banks and state agencies.
• Higher loan ceilings tied to realistic property valuations and lower special mortgage rates.
• Cutting transfer and mortgage registration fees to stimulate ownership transfers.

These are sensible short-term fixes. Yet they require coordination between state agencies, the Bank of Thailand, and commercial lenders, and they carry trade-offs: easing could raise credit risk if household leverage is already elevated.

The condo market slowdown: supply, capital and strategy

Colliers Thailand frames 2025 as a structural low point for Bangkok condos. A few specifics:

• Investment in new condo launches for 2025 fell to THB70.368 billion, compared with a historical normal above THB100 billion per year.
• Listed developers accounted for more than 83% of new supply, launching 14,323 units with investment near THB64 billion; non-listed developers withdrew or reduced exposure.

This concentration shows the importance of balance-sheet strength and brand recognition when buyers are scarce and credit rewards reliability. It also shifts the type of inventory coming online: developers are likely to prioritise smaller-to-mid-sized projects in well-located corridors, particularly along mass-transit lines and in central business districts.

Colliers expects a gradual rebalancing in 2026 with new supply projected at about 15,000 units and investment of around THB60 billion, still below long-term averages. For investors that matters: the market will not flood with units in 2026, which reduces the short-term risk of oversupply, but weak demand will keep yields under pressure.

What this means for buyers, investors and developers — practical steps

Here is how different market participants should act now, based on the facts.

For first-time buyers and owner-occupiers:

• Get a pre-approval early. With rejection rates near 40%, you cannot assume lending will be straightforward.
• Document alternative income thoroughly. If you are self-employed or earn online, assemble bank statements, tax filings, invoices and third-party contracts to create a comprehensive income profile.
• Consider properties along mass-transit lines and in central locations — these will see firmer rental demand and resale liquidity if financing remains tight.
• Negotiate with developers on valuation and incentives, such as developer-backed financing, lower down payments, or temporary interest subsidies.

For buy-to-let investors:

• Focus on rental yield and tenant profile rather than short-term capital gains.
