# Buying a Resale Condo in Bangkok: Step by Step

Buying a resale condo takes eight steps: set a budget and get a loan pre-assessment, view the unit and check the building, check the title deed and any mortgage, pay the reservation and sign the sale agreement, apply for the loan, get the debt-free letter from the juristic person, transfer ownership at the Land Office, and change the names with the building office and the utility meters. Condos for sale on DooAsset have a median price of about 154,758 baht per sqm.

## 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](https://dooasset.com/en/articles/resale-condo-transfer-costs-thailand/).

## 2. View the unit and check the building

- Use the [Condo Viewing Checklist](https://dooasset.com/en/articles/condo-viewing-checklist-bangkok/) 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?](https://dooasset.com/en/articles/can-foreigners-buy-condo-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.

## Frequently asked questions

### What document do I need from the building office to buy a resale condo?

A debt-free letter certifying that no common fees are owed, which the seller gets from the condominium juristic person. The Land Office needs it for the transfer.

### Can I buy a condo that is mortgaged?

Yes. The seller redeems the mortgage on transfer day, with the lending bank attending at the Land Office. Put this in the sale agreement.

### When should I apply for the loan when buying a resale condo?

Right after signing the sale agreement: the bank has to value the unit and approve the amount, which takes a different time at each bank, so leave a margin before the transfer date.
