How to secure a Thai mortgage

Regular income no longer guarantees mortgage approval in Thailand. Banks are also examining household debt, income records and whether borrowers consistently manage their finances.

A Government Housing Bank manager said high household debt can leave borrowers unable to take on additional monthly repayments, even when their salaries or business income appear adequate. The problem is particularly acute for applicants who already carry car loans, personal loans, credit-card balances and other consumer debt.

Unclear or inconsistent income documentation also creates difficulties. Small-business owners, freelancers, online merchants and self-employed workers may show substantial money flows in their bank accounts without demonstrating stable income or regular savings. Banks need to distinguish between money moving through an account and income that can reliably support a long-term mortgage.

The Government Housing Bank found that around 40% of applicants for home loans were approved between January and February 2026, resulting in a rejection rate of 60%. The figures highlight a widening gap between people’s ability to earn income and their ability to demonstrate sufficient, sustainable repayment capacity.

Kasikorn Research Center expects mortgage lending in 2026 to range from a contraction of 0.5% to zero growth. The outlook reflects continued pressure from elevated household debt and slower economic growth, while banks remain cautious about extending new credit despite relaxed loan-to-value rules.
