Viewing checklist

What to check when viewing a property in Thailand before buying

Thailand property viewing checklist: check moisture, noise, registered area, common spaces, lifts, building fees and reserve funds before making an offer.

What to check when viewing a property in Thailand before buying

Where to start

A good viewing should make the listing feel less polished. Photos tell you what the owner wants to show; twenty quiet minutes inside the actual unit can reveal the things that affect daily life and resale: a damp smell behind a wardrobe, traffic that cuts through closed windows, an air-conditioner that never quite cools the bedroom, or a view that depends on an empty development plot next door. The purpose of the visit is not to admire the finish. It is to discover what you would be buying when nobody is staging the room for you.

The building deserves almost as much attention as the unit. In a completed condominium, slow lifts, recurring closures, poorly kept service corridors and tired mechanical areas can tell you more about management than a pristine lobby. A pool is only an amenity if it is reliably open; parking only has value if your unit actually has the right to use it in the way you expect.

Then come the numbers that cannot be judged from a sofa. The listing area should be reconciled with the ownership document and registered plan for the specific condominium unit. Common fees, arrears, reserve capital and proposed major works need context as well: a large reserve can still be inadequate for an ageing building with expensive lift or façade work ahead.

This page is for choosing a completed condo or villa before purchase. It is not a new-build snagging inspection and it does not replace legal due diligence on title, seller authority or the sale agreement. Condominium financial records, unit liabilities and any managed-estate charges should be checked against the actual property and the rules in force when you buy.

Do's and don'ts

Do

  • Bring a charged phone, a small tape or laser measure, a flashlight, a simple plug-in charger and a written question list.
  • Revisit finalists at a different time of day, especially near a busy road, tourist strip, school, construction site or large shared pool.
  • Operate water, air-conditioning, windows, doors and included appliances rather than inspecting them only visually.
  • Photograph defects, meter details, each window view, parking and common areas where the owner permits it, not just the photogenic rooms.
  • Use unit documents for area and layout claims, and ask the seller to support building-finance claims with management records.
  • Ask the same core questions at every serious viewing so one property does not win simply because the agent gave a better sales presentation.
  • Record material promises separately and later check whether they appear in the transaction documents when they matter to the purchase.

Avoid

  • Do not clear a unit for moisture just because there is no obvious brown stain; odour, new paint, swollen skirting and marks behind furniture can be more revealing.
  • Do not turn your own measurement into the condominium's legal area or calculate price per square metre from an unsupported marketing number.
  • Do not stop at the lobby and pool. Service stairs, corridors, parking and heavily used areas often show management quality more clearly.
  • Do not accept 'the sinking fund is healthy' without the current amount, recent uses and known capital projects that may already need that money.
  • Do not confuse a debt-free selected unit with a financially strong building; individual arrears and building-wide collection are different questions.
  • Do not accept a viewing of a similar unit as a substitute for the property being sold when view, noise, condition, floor or orientation affect your decision.
  • Do not let artificial urgency shorten document access or remove the chance of a second viewing; a rushed process does not improve the property.

Schemes and red flags

Fresh cosmetic work only where water damage would appear

How it works

A corner, ceiling or wall is patched just before sale so an old leak or mould problem looks like ordinary redecorating.

Red flag

The paint tone changes locally, skirting is swollen, the room smells damp or nearby surfaces show older moisture marks.

What to do

Ask why the repair was done, inspect the adjoining surfaces, request the repair history and use a technical inspector where the underlying cause could be material.

A better unit is shown instead of the unit for sale

How it works

The buyer sees a quieter, brighter or renovated unit with the same nominal layout while the actual property is unavailable until after a commitment.

Red flag

The unit number changes, access is repeatedly postponed or differences in floor, orientation and condition are dismissed as irrelevant.

What to do

Make the buying decision only after inspecting the specific property and matching its unit number to the seller's documents.

Price per square metre uses a different area basis

How it works

The listing uses an area figure that does not match the registered area for the specific condominium unit, making the asking price appear cheaper on a square-metre basis.

Red flag

The agent cannot show where the area came from, or different sales materials quote different figures without a coherent explanation.

What to do

Use the ownership document and registered plan before comparing price per square metre; keep your room measurements as a separate usability test.

Presentation-quality common areas hide weak management

How it works

The lobby and pool remain attractive while major systems and finances are deferred until owners face a large repair programme or special assessment.

Red flag

Recurring lift failures, closed facilities, chronic leaks, vague budget answers or reluctance to support financial claims through the seller.

What to do

Inspect less polished areas and ask the seller for the latest annual report, balance sheet, reserve position, major spending and planned works.

A reserve figure is sold as proof of financial health

How it works

A large headline balance is presented without context about unit count, building age or capital works already competing for the same money.

Red flag

Nobody can explain the available reserve, committed projects or the history of special assessments.

What to do

Read the reserve alongside the budget, maintenance history and upcoming capital programme. There is no single safe reserve number for every Thai condominium.

Pressure replaces disclosure

How it works

Urgency is used to stop the buyer from revisiting, speaking with management or obtaining documents before money is committed.

Red flag

A supposed competing buyer is repeatedly cited while basic records, answers or access to the actual unit are withheld.

What to do

Separate price negotiation from verification. If basic information is conditional on immediate payment, treat that as transaction risk rather than a sales advantage.

How to measure area

Bring a tape measure, but use it for the right job. Measure whether a bed fits with sensible circulation, whether a dining table blocks a doorway, how deep the balcony is and how much wall is genuinely usable. Those checks tell you whether the floor plan works for your life; they do not replace the condominium's registered area.

For a condominium, start with the documents for the specific unit. Thailand's condominium framework requires the unit ownership document to state the area and the plan to show dimensions. If the listing, seller's brochure and unit documents do not agree, avoid using a price-per-square-metre comparison until you know which figure is actually registered.

Do not apply a universal shortcut to balconies, recesses or adjoining spaces. Check how the registered plan and ownership document treat the space in this unit. Something that looks physically connected to the apartment should not automatically be assumed to have the same status as the area advertised by the seller.

A villa needs a different approach because building area, land boundaries and the legal rights over each can sit in different documents. If the discrepancy is about registered boundaries, ownership or contract wording rather than furniture fit, move the issue into legal and survey due diligence instead of trying to settle it during a viewing.

FAQ

What should I bring to a property viewing in Thailand?
A charged phone, a note with your standard questions, a small tape or laser measure, a flashlight and a simple plug-in charger cover most buyer-level checks. Keep the floor plan open so you can mark differences while you are in the unit. Use your tools to test usability and obvious operation, not to dismantle equipment or certify electrical safety. Anything involving live electrical testing, concealed systems or a suspected structural issue belongs with a competent inspector.
How can I spot hidden moisture during a viewing?
Do not look only for a visible brown patch. A musty smell, isolated fresh paint, swollen skirting, soft plaster, dark sealant or marks behind furniture can be more informative. Pay extra attention around external walls, windows, air-conditioning lines and wet areas. If the potential problem is material, a viewing cannot replace moisture testing and diagnosis of the source.
How do I check noise if the viewing is in the middle of the day?
Turn the air-conditioning off and spend a few quiet minutes with the windows both closed and open. Listen for the lifts, corridor doors, road traffic, commercial premises and building equipment. If the property remains a serious candidate, return at the time that matches your risk: evening, weekday rush hour or weekend activity. A quiet midday appointment is only one sample, not proof of a quiet home.
What should I ask the condominium management before buying?
Start with the current common-area charge, parking rules and known major works. Ask the seller to provide or arrange access to the latest annual report and balance sheet, information on reserve capital, major recent expenditure and special assessments. Building-wide owner arrears are also useful context because weak collections can eventually affect maintenance. As a prospective buyer, do not assume the juristic office must hand every record directly to you; organise document access through the owner and transaction process.
How do I check whether the unit owes common fees?
Do not rely only on a seller saying the account is clear. For a condominium transfer, Thai law requires the relevant current debt-free certificate from the condominium juristic person before the Land Office can register the transfer under the applicable procedure. Build that certificate into the closing checklist and decide who clears any outstanding amount. A clean unit does not prove the whole building has strong collections, so review the building finances separately.
How do I know whether the building's reserve fund is enough?
There is no useful universal number. Compare the available reserve with the age and scale of the building, the condition of lifts and major systems, the annual budget, recent capital spending and works already being discussed. Thai condominium capital and other funds operate through the building's rules and general-meeting decisions, so one headline amount per square metre is not a safe benchmark for every project. The practical question is whether known obligations can be funded without an unexpectedly large owner assessment.
Is the area in the property listing the real condo area?
Treat it as a lead, not final evidence. For a condominium, reconcile the number with the ownership document and registered plan for the specific unit before using it in a valuation or price-per-square-metre comparison. Your tape measure is useful for room function and furniture fit, but it is not a substitute for the registered measurement. If the difference is material to the price, resolve it before committing significant funds.
How is this different from snagging a new-build condo?
A purchase viewing is about deciding whether an existing completed property, its surroundings and its building are worth buying at the proposed price. New-build handover is a later contractual process in which the buyer checks the delivered property against the agreed specification and records defects for rectification. Mixing the two can turn a selection visit into the wrong kind of inspection. If you are taking delivery directly from a developer, use the dedicated Thailand handover and snagging guide.

Expert view

I learn more from five quiet minutes with the air-conditioning switched off than from a freshly staged living room. A very good unit can sit inside a building that has postponed lift, façade or systems work for years, and that future bill is not visible in the asking price. I also separate two meanings of area: I measure rooms to see whether the home works, but I use the specific unit documents for the transaction number. A seller who is comfortable with a second visit, management questions and clear answers on fees, reserves and arrears gives me far more confidence than a discount that expires tonight. Before an actual purchase, I would still verify the legal and financial records for that unit under the rules current at the time of closing.
