Condo Buying Documents in Thailand, Sorted by Occupation and Buyer Type

Key Highlights

• Condo buying documents always fall into three groups, personal identity documents, income documents, and collateral documents for the unit itself, following the checklist published by the Government Housing Bank
• Salaried buyers need 3 months of payslips and a 6 month bank statement, while business owners and freelancers must add a commercial registration, proof of income tax filing, and 3 to 4 photographs of the business
• Every co borrower files a full document set of their own and is liable for the entire loan, and the mortgage interest deduction of up to 100,000 baht per year is split according to each owner's share of the title
• The Bank of Thailand announced on 14 May 2026 that the relaxed LTV rules allowing lending of up to 100 percent will run from 1 July 2026 through 30 June 2027
• Foreign buyers need one extra document set, including a Foreign Exchange Transaction form from the receiving Thai bank for inbound transfers above USD 50,000, plus written confirmation that the building still has foreign quota left

Why does paperwork slow down most condo deals in Thailand?

The condo buying documents a Thai bank asks for are not complicated on their own. They cover three questions. Who are you, how much do you earn, and which unit are you buying. Every lender in the country asks for the same three groups, and only the fine print differs between them.

What actually derails deals is timing. A reservation form usually gives you 7 to 30 days to submit a loan application, while some documents depend on other people. An employment certificate has to come from your HR department, a company registration extract has to come from the Department of Business Development, and a debt clearance letter has to come from the building's juristic person. Buyers who start collecting paperwork after paying the reservation fee often run out of runway and lose the unit they wanted.

The safer sequence is to have your personal and income documents complete before you view units, and to pull your own credit bureau report early so any problem surfaces while there is still time to fix it. Once you find the right unit, all that remains is adding the collateral documents.

What are the three groups of condo buying documents?

Group 1, personal documents that prove who you are

This group is identical across occupations and lenders. The Government Housing Bank lists a national ID card or government officer card, a house registration book, a marriage certificate, divorce certificate, death certificate or separation record where applicable, a name change certificate where applicable, and a copy of the spouse's ID card where applicable.

Two things trip buyers up here. If you are legally married, the bank will ask for your spouse's documents even when only one of you is borrowing, because property acquired during a marriage is treated as marital property under Thai law. And if your name has ever changed, the spelling on your ID, your house registration, and your bank account must be reconciled with a name change certificate attached to the file.

Group 2, income documents that prove you can service the loan

This is the group that decides your approved amount, and the group that varies most by occupation. Its centrepiece is a 6 month bank statement, which the lender reads to see whether income arrives consistently and how much is left after your outgoings. The Government Housing Bank advises keeping total debt service under 40 percent of income before you apply.

Group 3, collateral documents that identify the unit

For a condominium these are the sale and purchase agreement or reservation agreement, every page of the condominium unit title deed known as the Or Chor 2, and proof of ownership. Buying from a developer means the sales team assembles this set for you. Buying a resale unit means you have to request it from the seller yourself, which in practice is the slowest step in the whole process.

Extra documents by occupation and buyer type

Salaried employees, three core papers

Document	Condition or detail
Employment certificate or benefits certificate	Issued by HR, usually accepted only if issued within the last 1 to 3 months
Payslips for the last 3 months	Equivalent proof of salary received over the last 3 months is also accepted
6 month bank statement	For the account your salary is paid into
Withholding tax certificate, form 50 Tawi	Needed if you receive income from more than one source
Any other evidence of financial standing you hold	Such as savings certificates or fund holdings, with originals available for inspection

The catch for this group is variable income. Commission and overtime are usually counted only in part, and lenders often want a longer look back period for them. If most of your earnings come from variable pay, prepare 6 to 12 months of payslips rather than 3.

Business owners and freelancers, roughly twice the paperwork

Document	Condition or detail
6 month bank statement	Both personal accounts and the account clients pay into
Copy of the commercial registration, company registration, or juristic person registration	Whichever matches how the business is registered
Proof of income tax filing such as form PND 90 or PND 91	Must come with the payment receipt
Three to four photographs of the business	Showing the shopfront, the signage, and the working space
Copy of the professional licence	For regulated occupations such as doctors, engineers, and architects
Copies of purchase receipts or client contracts	Evidence that the business earns on an ongoing basis

The photograph requirement surprises almost everyone in this group and is a common reason for a second trip to the branch. Freelancers without a shopfront can usually substitute photographs of a real working space with the equipment they use, but it is worth confirming the format with the loan officer first. For eligibility rules in more depth, see the PropertyScout guide on whether foreigners can obtain a property loan in Thailand.

Joint applications, one full set per borrower

Applying jointly genuinely raises the approved amount, because the lender combines the incomes. The Government Housing Bank notes that lenders generally accept 2 to 4 borrowers including the lead applicant, and recognise registered spouses, parents and children, siblings, and other relatives whose relationship can be evidenced. Each co borrower submits a complete personal and income document set of their own.

• Personal documents for every co borrower, including their own spouse's documents where applicable
• Income documents matched to each co borrower's occupation, since the lead applicant's papers cannot stand in for them
• Evidence of the relationship, such as a shared house registration, a birth certificate, or a name change certificate when surnames differ
• A signed credit bureau consent form from every co borrower

Two points are worth settling before anyone signs. Liability is joint and several, meaning each borrower is answerable for the whole debt rather than a share of it. And the mortgage interest deduction of up to 100,000 baht per year is divided according to each person's registered share of the title, so not everyone claims the full amount.

What documents do you request from the seller?

Buying from a developer means the sales office issues the reservation form, the receipt, and the sale and purchase agreement. Buying a resale unit means you request the following yourself, and you should do it before paying a deposit rather than after.

Document to request from the seller	Why it matters and what to check
Every page of the condominium unit title deed, the Or Chor 2	Confirms the seller is the registered owner and shows existing mortgages or seizure notices
Copies of the seller's ID card and house registration	Checked against the name on the title deed
Debt clearance letter from the condominium juristic person	Required by the Land Department in order to register the transfer
The most recent common area fee receipt	Plus evidence that no water or electricity charges are outstanding
Copy of any sale and purchase agreement or reservation agreement already signed	Must come with proof of every payment made

The debt clearance letter is the single most commonly forgotten document and a frequent cause of postponed transfer dates. Many juristic persons take 3 to 7 working days to issue one, and will only issue it when the owner has no outstanding common area fees. If the seller is in arrears, that has to be settled before a transfer date can be booked at all.

Timeline for submitting documents from booking to transfer day

Five stages from reservation to transfer day

• Before reserving, complete your personal and income documents and pull your own credit bureau report
• On reservation day, collect the reservation form and the receipt for the reservation fee from the seller
• Within 7 to 30 days of reserving, file your loan application together with the sale and purchase agreement, and note that you may apply to several banks at once
• While the application is assessed, the lender sends a valuer to inspect the unit, so arrange access with the seller in advance
• On transfer day at the Land Office, bring your ID and house registration or passport, the unit title deed, the debt clearance letter, and the loan documents issued by your bank

The stage to leave the most room for is assessment, which typically runs 2 to 4 weeks and stretches further whenever the lender requests additional papers. Having the first two document groups ready before you reserve is the single most effective way to protect that timeline.

Which documents do people fail to get in time?

• An employment certificate that has aged out, since most lenders accept one issued only within the last 1 to 3 months
• A statement covering less than 6 months, or one from an account other than the salary account, which hides the consistency the lender is looking for
• The debt clearance letter from the juristic person, requested too late to arrive before the booked transfer date
• Tax filing evidence from business owners that lacks a payment receipt or e filing confirmation, rather than just the completed form
• Spouse documents in a registered marriage, often skipped because only one person is borrowing

One government measure ties directly to what you file on transfer day. Under the Cabinet resolution of 30 June 2026, the transfer registration fee is reduced from 2 percent to 0.01 percent and the mortgage registration fee from 1 percent to 0.01 percent, effective through 30 June 2027. The purchase price and the appraised value must each be no more than 7 million baht per contract, the mortgage amount no more than 7 million baht per contract, the buyer must be a Thai national individual, and the transfer and the mortgage must be registered on the same occasion. Foreign buyers do not qualify for this reduction and should budget the standard 2 percent transfer fee, customarily split with the seller by agreement.

What extra documents do foreign buyers need?

Foreign buyers add one group on top of the three above, and it is the group the Land Office scrutinises most closely. The key item is proof that the purchase money entered Thailand as foreign currency and was converted to baht by a Thai bank. For inbound transfers above USD 50,000 the receiving bank issues a Foreign Exchange Transaction form. Below that threshold, banks issue a credit note or a bank letter instead. PropertyScout has a full walkthrough of the FET form.

• A valid passport with copies of the pages showing your most recent entry stamp
• A Foreign Exchange Transaction form or equivalent bank certificate from the receiving Thai bank, stating that the purpose of the remittance is the purchase of a condominium unit
• Written confirmation from the condominium juristic person that the building is still within the 49 percent foreign ownership ceiling calculated on total unit floor area

The detail that causes the most trouble is name matching. The remitter named on the bank paperwork and the stated purpose of the transfer must match the person who will hold the title. If they do not, the Land Office may decline to register the transfer on the day. Background on the ownership ceiling is covered in the PropertyScout explainer on the 49 percent foreign ownership quota.

Frequently asked questions about condo buying documents

Which condo buying documents do I need if I pay cash rather than borrow

Paying cash removes the income group entirely. You still need the personal documents and the collateral documents, which means your ID or passport, house registration where applicable, spouse documents where applicable, the sale and purchase agreement, the unit title deed, and the debt clearance letter from the juristic person. Keep evidence of the source of your funds available, because your bank will ask about it when a large transfer is executed.

Can I apply to several banks at once, and how many document sets do I need

You can, and many buyers do in order to compare offers. Prepare one certified copy set per bank and sign every page as a true copy. Bear in mind that each application appears as an enquiry on your credit bureau report, so it is better to submit them within a short window rather than spread across several months.

How do resale documents differ from new build documents

The personal and income groups are identical. The difference sits entirely in the collateral group. A new build comes with a document pack from the developer's sales office, while a resale requires you to obtain the title deed copy, the seller's identity documents, and the debt clearance letter yourself. Allow at least 1 to 2 extra weeks for a resale purchase.

Does a complete file mean I can borrow the full purchase price

Your approved amount depends primarily on income and existing debt. The regulatory ceiling is currently relaxed, as the Bank of Thailand announced on 14 May 2026 that lending of up to 100 percent of the collateral value is permitted for contracts made between 1 July 2026 and 30 June 2027. That is a regulatory ceiling rather than any assurance that a given application will be approved in full.

Can a foreigner get a Thai mortgage for a condo

Some lenders offer financing to foreign buyers, typically at shorter terms, higher rates, and lower loan to value ratios than for Thai nationals, and often with a work permit and Thai sourced income as conditions. Many foreign buyers therefore purchase in cash or finance abroad. Whichever route you take, the Foreign Exchange Transaction paperwork still has to show that the funds arrived from overseas in foreign currency.

Summary

Condo buying documents come down to three groups every time, personal identity, income evidence that varies by occupation, and the collateral papers for the specific unit. The first two can be assembled before you view a single property, and the third is added once you decide. Working in that order keeps you inside the reservation deadline and leaves time to compare offers from more than one lender.

Once your file is ready, the next step is finding a unit that matches the amount you can realistically borrow. Browse verified listings on PropertyScout to see units the owner has confirmed, or work with an agent who speaks your language to chase the seller and the juristic person for the remaining paperwork before transfer day. Background reading on the whole purchase process is available in the PropertyScout guide to buying property in Thailand.
