Applying for a home loan in Thailand means getting pre-approved, making an offer, formally applying with full documentation, finalising the loan, and signing the mortgage contract at the Land Department. The process takes about 3–10 days once documents are submitted. Thai banks rarely lend to non-residents for condos, so foreign buyers usually need a work permit and local income, or use overseas or developer finance.

What Are The Bank Of Thailand’s Housing Loan Regulations?

The Bank of Thailand’s housing loan regulations that came into effect on April 1st of 2019 put stricter limits on the Loan to Value ratio (LTV) for second and third homes as well as those valued over 10 million baht.
Put simply, while commercial banks in Thailand offer different rates based on many personal factors, the highest possible mortgage as a percentage of those applicable property values became smaller. As a result, some required down payments grew larger.
The Bank of Thailand’s housing loan regulations on properties under 10 million baht in value can be broken up into the following key points:
- The first house’s LTV can be 90-95%, meaning a 5-10% down payment.
- If the owner has been paying that first house loan for at least 3 years, a second house’s LTV can be as high as 90%. If the first loan has been paid for less than three years, the second house’s maximum LTV is 80%. The down payment will be 10-20% based on the length of the first loan payment.
- The maximum LTV from the third house and onward is 70%, meaning a down payment of 30%.
The following rules apply to properties valued at more than 10 million baht:
- The maximum LTV on the first two houses is 80% and the down payments are 20%.
- The maximum LTV from the third house and onward is 70%, meaning a down payment of 30%.
Why Are Property Mortgage Regulations Important?
Property mortgage regulations are important because they help to maintain the health of the property sector and the overall economic system. If LTV ratios are higher and down payment requirements are lower, it can lead to over-speculation within the market. This, in turn, can make it harder for average people to buy property.
2020 research published in The Review of Financial Studies also found that housing speculation can make economic downturns worse. This was part of the reason for the 2008 global financial crisis.
In the past, people could buy a property in Thailand through a housing loan with no down payments. The Bank of Thailand’s mission is to keep the economy healthy and the real estate market fair with higher barriers to entry.
Home Loan Real Estate Collateral Types
The 4 real estate types that can be used as collateral for a home loan in Thailand are house, townhouse, commercial, and condominium. Different regulations and individual bank policies may apply depending on the type of property.
For example, commercial loans require more extensive documentation in the form of things like corporate registration certificates, financial statements, employment contracts, shareholder registration, and more. Maximum installment periods can be as short as 7 years while total loan values tend to be much higher than residential properties.
Each bank will have its own policy toward residential categories like houses, townhouses, and condominiums, with different rates applying to each one.
Yet another category of loan with a maximum LTV rate of 90% is for house building loans. That percentage is based on the appraised value of the land and future building. A similar category of loan for constructions or repairs on existing homes is also available.

How To Prepare For A Mortgage Application

When applying for a mortgage, the most important thing you can do to prepare is to secure your overall financial situation. This includes clearing all debts, ensuring that your credit history is clean, and maintaining regular bank account inflows for at least 6 months leading up to the application.
Aside from creating a stable financial picture for the Thai lenders, you’ll need to gather several other documents that verify your identity and circumstances in the Land of Smiles.
Finally, you should have a clear picture of your goals before setting an appointment. How much can you afford to pay upfront? What duration are you hoping for on the mortgage? Will you take a loan out to pay for furnishings and household goods?
Many applicants fail to receive a home loan. Answering those questions and making the following preparations will dramatically increase your probability of getting a mortgage and provide greater peace of mind.
1. Decide How Much You Want To Borrow
Deciding how much you want to borrow, and therefore how large your down payment will be, is the most important piece of information to decide before setting up a home loan. This can impact the interest rates you’re offered, the loan duration you can handle, and ultimately the amount of money you’ll save over time.
How Large Can A Home Loan Actually Be?
How large a home loan can actually be depends on the applicant’s salary, current debt, and the bank’s policies. Commercial banks will generally use 40% of a person’s monthly salary as a baseline and subtract the monthly cost of any recurring debt for things like cars or other loans.
Taking a salaried employee making 40,000 baht per month as an example, the maximum monthly payments they could make would be calculated as follows:
40,000 x 40% = 16,000 per month. If the employee has a monthly debt of 6,000 baht, it would be subtracted from this for a potential monthly installment of 10,000 baht.
Total loan amounts are calculated based on a ratio involving a 7,000 baht monthly installment to a loan total of 1,000,000 baht. An employee’s total home loan value would be calculated as follows, assuming they have no debt:
(1,000,000 x 16,000) / 7,000 = 2,285,714 baht total.
This is the maximum mortgage that they would offer to the applicant. However, Bank of Thailand regulations apply, so if this number exceeds the possible 90% LTV ratio for a first house, they would have to lower the total to meet with those rules.
2. Agree On The Interest Rate
Agreeing on a loan’s interest rate is one of the factors that determines how much extra money your real estate will cost you. Different banks may offer slightly different rates, and these rates may be structured differently over the life of the loan. For that reason, assessing different rates and finding the best one for you is crucial.
Prime debtor lending rates set the Minimum Loan Rate (MLR) which is used as a basis for floating interest rates. This fluctuates over the years, so averaging the interest over the life of the loan is a useful way to compare rates.
3. Settle On A Loan Duration
Settling on a loan duration can be difficult as it means choosing between easier payments but more interest overall or a strict budget in the near term with less paid to the bank in the end.
Your age will factor into how long your loan duration can be, too. In Thailand, the typical length offered is from 15 to 30 years. However, mortgages cannot be so long that they’re still active after the borrower has turned 70.
4. Prepare To Pay Monthly Installments On Your Home Loan
Preparing to pay monthly installments on your home loan is often overlooked when entering a mortgage contract. Having the down payment ready is step one, but leaving a cushion for yourself to make early payments and to have a safety net for emergencies will put you even more at ease.
On top of having a healthy sum of cash ready, evaluating your circumstances to ensure you’re ready to continue with payments throughout the life of the loan is just as crucial.
What Mortgage Payment Strategies Are Available In Thailand?
The 4 main mortgage payment strategies available in Thailand are:
-
- Floating rate mortgages. Each bank offers mortgage interest rates based on the Minimum Retail Rate (MRR) supplied by the Bank of Thailand. Floating rate mortgages follow this rate, usually on a 6-month or yearly basis. Such mortgages may be more attractive in times of inflation when rates are already high.
- Fixed rate mortgages. Banks may offer a fixed rate over the duration of a loan based on current rates and future rate projections. This type of loan can be beneficial when interest rates are low, though it may end up more costly if rates drop further.
- Balloon mortgages. A type of mortgage sometimes offered by banks where monthly payments are smaller during the life of the loan but end with a final, large installment. The advantage of these loans is that the final installment may not be counted toward your average monthly payments, making a larger overall loan possible.
- Bridge mortgage. This is a short-term loan that may have a duration of as little as a few months or as long as two or three years. This mortgage may use your current home as collateral and is a useful option when trying to buy a new property before you’ve sold an existing one.
