Bangkok condo purchasers are being turned down for mortgages mainly because of excessive household debt, unstable income and poor credit history, made worse by rising interest rates. The Bangkok Post reports that the mortgage rejection rate rose to 44.9% in the first half of 2026. For agents, including those working with Marathon 360, a London company that supplies pre-warmed, qualified investor leads, finance readiness now matters as much as interest in a unit.
The numbers behind the rejections
The figures come from a survey by the Housing Business Association, conducted among its members and reported by the Bangkok Post. It found the rejection rate climbed to 44.9% in the first half of 2026, up from 39.8% a year earlier. That is an increase of 5.1 percentage points.
The survey also set out why applications failed. Excessive debt was the main reason, accounting for 37.3% of rejections. Unstable income followed at 33.3%, and poor credit history at 21.6%.
Sunthorn Sathaporn, president of the Housing Business Association, told the Bangkok Post that the housing market remained weak, with mortgage rejections continuing to pose a major obstacle for homebuyers.
Debt and interest rates are the pressure points
Household debt sits at the centre of the problem. According to Bank of Thailand data cited by the Bangkok Post, Thailand's household debt stood at 16.4 trillion baht in the first quarter, equivalent to 85.9% of GDP.
Interest rates add to the strain. Mr Sunthorn said rising rates are adding to the burden on borrowers and making it harder for potential purchasers to secure mortgages. Pornnarit Chounchaisit, president of the Thai Real Estate Association, said rising rates could further restrict access to mortgages.
Mr Pornnarit also raised a timing issue. He said the large number of property transfers in the first half may have been partly driven by people rushing to complete purchases before government measures expired. His bigger concern was whether those with weaker financial profiles could obtain loans at all. In his words, condos may sell well, but the key question is whether purchasers will be able to secure mortgages when it is time to transfer ownership.
Supply, flooding and a market that favours purchasers
Demand has not disappeared. Pitipat Preedanont, president of the Thai Condominium Association, said the condo market resumed growth in the first half. He described condos as an alternative for those who cannot afford landed homes close to Bangkok, as units near mass transit stations offer better access at similar prices to houses farther out.
Developers remain cautious, however. Savills (Thailand) told the Bangkok Post that recent floods weakened homebuyer confidence and led developers to postpone more than 1,000 condo units planned for the third quarter. Phattarachai Taweewong, senior director at Savills, pointed to weak purchasing power, tighter mortgage approvals and high development costs.
According to Savills, Bangkok had 167,841 condo units available for sale as of the third quarter of 2026, of which 103,191 had been sold, a sales rate of 61.5%. Savills expects the market to favour purchasers for the rest of 2026, with some developers cutting prices by more than 50% on completed units. It expects high-end branded residences in central Bangkok to perform best, supported by affluent and foreign demand.
What this means for agents
A signed reservation is not a completed sale when nearly half of mortgage applications fail. Agents in the Thailand market can reduce that risk with a few practical steps.
- Ask about financing early. Find out whether a client is buying with cash, a local mortgage or overseas funds before arranging viewings.
- Check the three common failure points. Discuss existing debt, income stability and credit history openly, since these explain most rejections in the survey.
- Plan for the transfer date. Off-plan purchases face a financing test at handover, so confirm a client's ability to borrow at that point, not just today.
- Watch the discounting. With developers clearing stock, clients with confirmed funds may find better terms on completed units.
- Focus on clients with clear capacity. Foreign and affluent demand is expected to support the top end of the market.
Working with pre-warmed, qualified investors means less time lost on deals that collapse at the bank. Marathon 360 works as a partner to agents on lead generation for agents, supplying investor leads that are qualified before they reach you.
