Mortgage Types Compared — Thailand 2026

Choosing the Right Mortgage in Thailand

Selecting the right mortgage type is one of the most important financial decisions in the buying process. The wrong choice can cost you tens of thousands over the life of the loan. This guide explains every mortgage type available in Thailand and helps you choose.

Types of Mortgages Available

Thai home loans have a distinctive structure. Promotional fixed rate provides a low fixed rate for 1-3 years — this is the headline rate banks advertise. After the promotional period, the loan reverts to a variable rate based on MRR (Minimum Retail Rate) minus a small discount. GH Bank subsidised loans offer the lowest rates for qualifying Thai nationals, with special programmes for first-time buyers and affordable housing. Full-term fixed rates are rare in Thailand — the promotional-then-variable structure is standard across all lenders

Head-to-Head Comparison

The promotional rate is just the first 1-3 years — what matters is the reversion rate (MRR-based) you pay for the remaining 20-27 years. Compare the full-term cost, not just the teaser rate. GH Bank beats all commercial bank offers for qualifying properties and borrowers. Plan to refinance every 3 years when the promotional period expires to get a new promotional rate from a competing bank

Which Type Is Right for You?

Your ideal mortgage type depends on your risk tolerance, financial stability, and market outlook.

Choose fixed rate if you value payment certainty, are on a tight budget with little room for payment increases, or believe rates will rise. Choose variable rate if you can absorb payment increases, want the lowest possible initial cost, or believe rates will stay stable or fall.

Consider your loan term carefully. Shorter terms mean higher monthly payments but dramatically lower total interest. Our mortgage guide provides a detailed analysis of how term length affects total cost.

Expert Tips for Thailand

Always check GH Bank first — their subsidised rates beat commercial banks. Time purchases during government fee reduction campaigns for transfer and registration savings. The reversion rate after 1-3 years is the real cost — plan to refinance when the promotional period expires. Make prepayments after the lock-in period when they become penalty-free

Refinancing Between Types

If you chose the wrong type, or if market conditions change, refinancing is always an option. Read our refinancing guide for a step-by-step walkthrough of switching products or lenders.
