Buying a Resale Condo in Bangkok: Step by Step

1. Set a budget and get a loan pre-assessment

As of 4 Oct 2026 condos for sale on DooAsset have a median price of about 154,758 baht per sqm, and the median one-bedroom unit costs 5.98 million baht. Ask a bank for a preliminary loan amount before you search, and keep money aside for transfer-day costs: see Transfer Day Costs for a Resale Condo in Thailand.

2. View the unit and check the building

• Use the Condo Viewing Checklist for the unit.
• Ask for the common fee per sqm per month, and the balance of the building's sinking fund.
• Look at the lifts, parking, and any major repairs the building has planned.

3. Check the title deed

• Ask for a copy of the condominium title deed and check the owner's name, unit number and area against the unit you saw.
• See whether the unit is mortgaged to a bank. If it is, the seller must redeem it on transfer day, with the seller's bank attending at the Land Office.
• If the buyer is a foreigner, have the foreign quota confirmed: see Can Foreigners Buy a Condo in Thailand?

4. Reservation and the sale agreement

The agreement should state:

• The price, the reservation money, the deposit and the balance due on transfer day.
• The agreed transfer date, and what happens if either side defaults.
• Who pays the transfer fee, taxes and duties.
• The furniture and appliances included in the price.
• What happens if the bank does not approve the loan.

5. Apply for the loan

The bank appraises the unit and decides the loan; timing depends on the bank. Apply right after signing the sale agreement and leave time before the transfer date.

6. The debt-free letter

The seller must get a letter from the condominium juristic person certifying that no common fees are owed. The Land Office needs it to register the transfer.

7. Transfer day at the Land Office

• Buyer, seller (or their attorneys) and any banks involved attend together.
• Pay the agreed fees and taxes, then receive the condominium title deed endorsed with the buyer's name.
• Check the name, unit number and area on the deed once more before you leave.

8. After the transfer

• Tell the juristic person about the new owner, and collect key cards and parking cards.
• Change the names on the electricity and water accounts, and move your house registration if you will live there.
• Record the meter readings on handover and make sure the seller has paid all outstanding bills.
