Why Thai landlords ask for a 2-month deposit and 1 month in advance

Last checked 6 October 2026 · 6 min read · English

Newcomers are often surprised to hand over three months' rent before they get the keys. In Bangkok, "two plus one" is the standard for condo rentals: a security deposit of two months' rent and the first month paid in advance. Here is why, what the law says, and how to make sure you get your deposit back.

What each payment is for

The first month in advance

Rent in Thailand is paid at the start of each month, not the end. The first payment simply covers your first month in the unit.

The two-month deposit

The deposit protects the owner against unpaid rent, unpaid utilities and damage beyond normal wear and tear. Most Bangkok condos are let fully furnished, often with expensive furniture and appliances, and most owners are individuals renting out one or two units. If a tenant leaves early or the unit needs repairs, the deposit is the owner's only practical protection, because pursuing a tenant who has left the country is slow and costly. Two months is enough to cover a missed month and a typical repair bill.

The booking deposit

Before the lease is signed, most owners ask for a booking deposit, usually one month's rent, to take the unit off the market. It is credited towards your signing payment, but if you change your mind it is normally not refunded.

When the deposit is not returned

The most common reason tenants lose their deposit is leaving before the end of the lease. Most leases state that the owner keeps the full security deposit if the tenant moves out early, and because it is in the contract you signed, the owner is usually entitled to it. If there is any chance you will need to leave early, negotiate a diplomatic clause before you sign, and read every clause about notice, penalties and the deposit carefully.

What the law says

Thailand's Contract Committee treats residential leasing as a controlled business. The current rules, in force since 4 September 2025, apply to anyone leasing three or more residential units, such as condos, houses and apartments (hotels and dormitories are excluded). For these landlords:

• Deposit and advance payments together may not exceed three months' rent for monthly-paid leases.
• The deposit must be returned at the end of the lease, within 7 days if there is no damage, or 14 days after deducting repair costs.
• Utilities may not be charged above the official rates, and normal wear and tear may not be charged to the tenant.
• A move-in condition report signed by both sides must be attached to the lease.
• The tenant may end the lease after half the term with 30 days' written notice.
• Breaches can lead to a fine of up to ฿200,000, imprisonment of up to one year, or both.

The common "two plus one" fits within the three-month limit. An owner who rents out only one or two units is not covered by these rules; the lease is governed by the Civil and Commercial Code and by what both sides agree in the contract. That is why the lease wording on deposits matters.

The rules have changed several times: in 2018 they applied to landlords with five or more units and capped deposit and advance rent at one month each; a 2019 revision moved to a three-month combined cap; the 2025 notification lowered the threshold to three units. Older articles online may quote outdated rules.

When you might pay less

• Serviced apartments often take one month's deposit, especially for shorter stays.
• Long or company leases sometimes allow a lower deposit or a bank guarantee instead of cash.
• Negotiation: a strong tenant profile, a longer lease or paying several months in advance can help.

How to get your deposit back in full

1. Document move-in: photos of every room, meter readings and a signed inventory and condition report.
2. Report problems early in writing, so they are not blamed on you later.
3. Give notice as the lease requires, usually 30 days.
4. Before moving out: have the air-conditioning serviced, clean the unit and pay the last utility bills.
5. Do a joint inspection against your move-in photos, and agree any deductions in writing.
6. Agree the return date and the account the deposit will be paid into.
