Buying a Thai condo is well-documented; turning it into a rental that actually earns — legally and without surprises — is where owners need a map. This plain-English guide covers whether a foreigner can be a landlord, the 3-year lease-registration rule, how rental income is taxed (including the 5% company withholding), screening tenants and setting a fair deposit, the lease clauses that matter, self-managing vs hiring a management company, and why Airbnb-style short lets are mostly illegal. Unbiased, never paid placement, and not legal, tax or financial advice.
A foreigner can rent out their own freehold unit; write a 1-year lease (under 3 years = no Land Office registration), screen the tenant and take the standard 2 months deposit + 1 month advance, keep paying the building’s common-area fees yourself, declare the rental income on your Thai tax return, and decide whether to self-manage or hand it to a management company for ~5–10% of rent. Skip daily Airbnb lets — under the Hotel Act they’re mostly illegal for a standard condo.
Renting out a unit you own in freehold is a normal, legal use of your property — and importantly, collecting rent on your own condo is treated as passive investment income, not “work,” so it does not require a Thai work permit. What crosses the line is actively running a letting business or a hotel-style operation, which needs the right company structure and licences. For your own one or two units, the legal questions that actually matter are simpler: a clean lease, declaring the income, and respecting your building’s rules. Confirm the specifics for your situation with a Thai lawyer — this is general information, not legal advice.
Thai law treats residential leases by length. A lease of 3 years or less needs no government registration — a written, signed agreement between you and the tenant is fully valid and is the standard for ordinary tenancies. A lease longer than 3 years is only enforceable beyond the three-year mark if it is registered at the Land Office, which triggers a lease registration fee of 1% of the total rent across the term plus 0.1% stamp duty.
A 1-year term with a renewal option keeps you under the 3-year line (no registration, no 1% fee), lets you reset the rent annually, and still gives a good tenant a clear path to stay. Multi-year registered leases are mainly for commercial deals or tenants who want long, secured tenure — rare for a residential condo.
Rent is assessable income and must be declared on your annual Thai return (PND 90/91). You choose one of two ways to deduct costs, then pay progressive personal income tax on the net.
Keep every receipt and use a Thai accountant once the numbers are meaningful. See tax for expats. None of this is tax advice.
Set the rent to recently agreed lets of comparable units in the same building or block — same size, floor band, view and furnishing — not to optimistic asking prices that have sat unrented. An empty unit earns nothing, so a slightly keener rent that fills fast usually beats a punchy rent that leaves the unit dark for two months. Factor in furnishing quality, the building’s amenities and management, and the season (the cool, high season fills units fastest). Good photos and an honest listing are the cheapest void-reducers you have.
The single biggest protection against trouble is choosing the right tenant before you sign. A light, fair screen covers most risk:
Note that you (or your agent) will likely need the tenant’s details to file the TM30 notification of a foreigner staying at your address — a landlord/possessor obligation worth knowing about up front.
The residential standard is two months’ rent as a security deposit plus one month’s rent in advance — three months up front in total. The deposit covers unpaid rent and damage beyond fair wear and tear and must be returned at the end minus itemised, legitimate deductions. Document the unit at move-in with dated photos and a signed inventory so any deduction is defensible; that single habit prevents most deposit disputes.
Consumer-protection rules aimed at people who rent out five or more units cap the deposit at one month and advance at one month and demand prompt return. A single-unit private landlord has more latitude on amounts, but a fair, itemised, timely return is still what Thai courts expect — don’t treat the deposit as extra income.
Reuse one solid, lawyer-reviewed template for every tenancy. A residential condo lease should pin down:
A bilingual Thai/English lease means both parties — and a Thai court, if it ever comes to that — read the same terms. A starting point is our lease template; have a lawyer review your version once, then standardise on it.
Here is the trap owners forget: the monthly common-area fee and sinking-fund contributions are your obligation to the condominium juristic person, not the tenant’s — the building chases the owner. Smart landlords build those into the rent and keep paying them directly, so a tenant’s lapse can never push the unit into arrears (which would later block the debt-free letter you’ll need to sell). Utilities — electricity, water, internet — are the tenant’s, billed directly or reimbursed against the bills. Write all of this into the lease.
It’s time versus margin — and distance. One unit nearby? Self-managing is realistic. Several units, or living abroad? A company usually pays for itself in fewer voids and less stress.
Read exactly what the fee does and doesn’t include, and how repairs are authorised and capped. See property management fees for landlords for a full breakdown.
Tempted by nightly rates? For a standard condo the answer is almost always no. Thailand’s Hotel Act makes renting accommodation for periods under 30 days a hotel business requiring a hotel licence a normal unit cannot obtain — so repeated daily/weekly letting risks fines, and most condominium by-laws separately ban it and report offenders. Monthly and longer rentals are the legal residential market and what this whole guide is built around. Full detail in short-term rental & Airbnb laws.
Whether you self-manage or hand it over, list it where serious long-stay tenants and relocators are already looking across Thailand.

General information only — not legal, tax, immigration or financial advice. Thailand’s rules on foreigner landlords and work-permit treatment of rental income, lease registration and the 3-year threshold, Land Office lease-registration fees and stamp duty, personal income tax on rent (standard vs actual-expense deductions and progressive rates), the 5% withholding when a tenant is a company, land-and-building tax for rented units, security-deposit and consumer-protection rules (including the five-or-more-units provisions), TM30 notification duties, condominium juristic-person by-laws, and the Hotel Act limits on stays under 30 days all change over time and are applied case by case by individual condominium juristic persons, Land Offices, the Thai Revenue Department and local authorities. Figures such as deposit norms and management-fee percentages are typical market ranges, not fixed rules, and vary by building and negotiation.
