Market overview

Thailand's home loan market is dominated by Bangkok Bank (BBL), SCB, Kasikornbank (KBank), Krungthai Bank (KTB), TMB Thanachart, and the state-backed Government Housing Bank (GH Bank). Most loans use a 1-3 year fixed teaser rate (typically MLR-X% where MLR is each bank's Minimum Loan Rate) blending into MLR + spread thereafter. Bank of Thailand held its policy rate at 2.25% through 2025, supporting low headline rates by ASEAN standards.

Why 5.75% is the typical rate

5.75% reflects a typical 3-year fixed teaser rate for a salaried Thai borrower at 80% LTV in early 2026. After the fixed period, rate resets to MLR + 0.5-1% (current MLR ~6-7%). GH Bank rates are 30-60 bps lower for first-time buyer programs.

Tax & regulatory notes

Mortgage interest is deductible up to THB 100,000/year from personal income tax for owner-occupied homes (lifetime cap). Property transfer fee is 2% of appraised value (often split between buyer and seller). Specific Business Tax (SBT) of 3.3% applies if sold within 5 years of acquisition; stamp duty of 0.5% applies otherwise. Mortgage registration fee is 1% of loan amount (capped at THB 200,000).

❓ FAQ (Thailand)

Common questions in Thailand.

Can foreigners get a Thai mortgage?

Mostly no — Thai banks rarely lend to foreign nationals for property purchases. Exceptions: foreigners with Thai spouse (loan in Thai spouse's name with foreign spouse as supplemental income), foreigners with Long-Term Resident (LTR) visa applying through MBK Guarantee or specific BBL programs, and condominium purchases by foreigners with established Thai bank account history. Foreign land ownership is constitutionally prohibited; foreigners can own condos up to 49% of building floor area.

Thai mortgage interest tax deduction — how much can I claim?

Up to THB 100,000 in mortgage interest paid per tax year, applied as a deduction against personal income tax. This is a lifetime cap per individual, not annual. For a typical THB 4.5M mortgage at 5.75%, annual interest is around THB 258,000 — meaning the THB 100,000 cap is exhausted in roughly Year 4 of the loan. Married couples can each claim THB 100,000 separately if both names are on the title and loan.

GH Bank vs commercial banks — which is cheaper?

GH Bank (Government Housing Bank) is typically 30-60 bps cheaper than BBL/SCB/KBank for first-time buyers earning under specific income thresholds (THB 50,000/month for the most subsidized tier). Standard GH Bank rates 5.25-6.25% vs commercial 5.75-7%. Trade-off: GH Bank loan approval can take 45-60 days vs 25-30 days at commercial banks. For mid-to-high-income buyers above GH Bank thresholds, commercial banks offer better service and faster processing.
