Which Condo Project Is Best in Thailand, 8 Criteria to Decide

Key Highlights

• Which condo project is best cannot be answered with a brand name alone, because the same developer delivers different results in different locations and different launch years.
• All 8 criteria below can be verified by you, without relying only on what the sales office tells you.
• The three that deserve the most weight are delivery track record, build quality visible in the developer's older projects, and juristic person management after handover.
• Three public documents do most of the work, the EIA status, the construction permit, and the draft condominium regulations.
• Foreign buyers carry two extra checks, the 49 percent foreign ownership quota remaining in the building and how the developer handles the paperwork for funds transferred from abroad.

Why is a brand name the wrong answer to this question?

Ask which condo project is best in Bangkok and you will usually hear the same two or three developer names. That answer is hard to act on. The same developer runs projects that age well and projects with recurring building system problems, depending on the contractor used, when construction happened, and the budget set for that particular location.

This guide does not rank brands. There is no public Thai dataset that scores individual developers in a way anyone can audit, so a ranking would be an opinion dressed as a fact. What works better is a fixed set of criteria you apply yourself, then use to compare the two or three projects on your shortlist against the same standard.

If you only have time for 3 checks, which come first?

Most buyers visit a project a handful of times before deciding. If you have to narrow it down, check these three in this order.

• The developer's delivery track record, because it is the only signal that tells you whether the building will be finished on schedule, and it is the one risk you cannot fix later if you choose wrong.
• Build quality visible in the same developer's projects that are 5 to 10 years old, because a show unit tells you what the materials look like on day one, not what they look like after five years of use.
• Juristic person management after handover, because it decides whether the shared facilities stay usable or decline year by year, which feeds directly into resale value.

The other five criteria matter too, but most of them involve trade offs you can accept knowingly, such as paying a higher common area fee for facilities that are properly maintained. The three above are the ones money cannot fix afterwards.

8 criteria for choosing a condo project, and how to verify each

Every criterion below uses the same sub headings so you can compare across projects directly. Open the two or three projects on your shortlist and fill in the same fields for each.

Criterion 1, developer track record and completed projects

Check point	Detail
What to look at	How many projects this developer has completed and transferred to owners, especially projects in the same price bracket and size as the one you are considering
How to verify it yourself	Ask the sales office for a list of completed projects, then search those names independently and compare the original transfer date with the date units were actually transferred. If the developer is listed on the Stock Exchange of Thailand, the annual report lists recognised projects in full
Warning sign	A developer whose portfolio is all projects under construction with no fully delivered project, or a pattern of postponed transfer dates across several projects
Weight if buying to live in	Highest, especially when buying off plan
Weight if buying to invest	Highest, because every month of delay is a month of rent you do not collect

Criterion 2, construction quality and the materials actually used

Check point	Detail
What to look at	The systems hidden behind walls, such as waste pipe routing, bathroom ventilation, and where the air conditioning compressor sits. These cause more trouble than the visible floor finish
How to verify it yourself	Ask for the material specification in writing rather than taking the show unit description at face value, then compare the brand and model of sanitary ware, doors, and glazing against other projects at the same price point
Warning sign	Specifications written so loosely that they can mean several things, such as quality tiles with no brand or size named, and contract clauses that let the seller substitute equivalent materials without notice
Weight if buying to live in	High, because you live with it daily
Weight if buying to invest	Medium, since tenants weigh location and price more heavily than finishes, though repeat repair costs eat into returns over time

Criterion 3, juristic person management after handover

Check point	Detail
What to look at	Who will manage the condominium juristic person after transfer, whether it is a company within the developer's group or an external firm, and how many years the management contract runs
How to verify it yourself	Under the timeline used in practice, the developer must call the first general meeting of co owners within 180 days of the first unit transfer, then register the juristic person with the Land Department within 30 days of that resolution. Ask the sales office how the project has planned both steps, and ask to read the draft condominium regulations before you pay a reservation fee
Warning sign	The sales team cannot answer questions about the juristic person at all, or says it has not been decided yet when handover is close
Weight if buying to live in	High, because it affects daily life and your monthly outgoings
Weight if buying to invest	High, because a building with declining facilities is harder to rent and loses resale value faster

Criterion 4, real occupancy and the share of units rented out

Check point	Detail
What to look at	How many units are actually lived in compared with the total unit count, and how many owners bought to rent out rather than to occupy
How to verify it yourself	No Thai authority publishes this per project. What works is visiting after dark on a weekday and counting the share of units with lights on, repeating it on a second evening, then counting how many rental listings for that project are currently live and comparing that with the total unit count
Warning sign	An unusually high share of rental listings compared with neighbouring projects in the same area, which usually means oversupply and downward pressure on rent
Weight if buying to live in	Medium, since buildings with more resident owners tend to maintain shared areas better
Weight if buying to invest	The highest among the secondary criteria, because it tells you how many units yours will compete with inside the same building

Criterion 5, resale prices of the developer's older projects nearby

Check point	Detail
What to look at	The price per square meter of projects the same developer built in that area or nearby, compared with the original launch price of those projects
How to verify it yourself	Search the older project names on sale and rental platforms, read the current asking price per square meter across several listings rather than one, then compare with the launch price you can find in older coverage
Warning sign	Many long standing sale listings in the same developer's older nearby projects at a price per square meter clearly below the area average
Weight if buying to live in	Medium, because you will still need it on the day you sell, even if that is not the goal today
Weight if buying to invest	High, because returns come from both rent and the resale spread

Criterion 6, EIA status and the construction permit

Check point	Detail
What to look at	Whether the environmental impact assessment report has been approved and whether the construction permit has been issued. According to the Office of Natural Resources and Environmental Policy and Planning, a residential building with 80 units or more, or with a usable area of 4,000 square meters or more, must complete this report before applying for a construction permit, and the threshold is not tied to building height
How to verify it yourself	Check the status yourself in the database of the Office of Natural Resources and Environmental Policy and Planning at eia.onep.go.th by searching the project or developer name, and ask the sales office for a copy of the construction permit at the same time
Warning sign	A project selling units and collecting reservation fees while the report is still under review. Read the refund terms on the reservation form in full before paying
Weight if buying to live in	High for projects that have not started construction, and much lower for completed buildings
Weight if buying to invest	High for the same reason, since it affects both the transfer date and your holding cost while you wait

Criterion 7, unit size and layout against the legal minimums

Check point	Detail
What to look at	The real unit area and bedroom area on the floor plan against the legal minimums. Under Ministerial Regulation No. 55 of 2000 issued under the Building Control Act of 1979, a unit in a residential building must be at least 20 square meters, a bedroom must be at least 8 square meters, and its narrowest side must be at least 2.50 meters
How to verify it yourself	Ask for a plan with dimensions in meters on every side, then measure it against furniture you already own. A five foot bed is 1.50 meters wide, so in a bedroom at the 2.50 meter minimum you are left with roughly 1 meter of walking space beside it
Warning sign	Plans that state only the total area in square meters without room by room dimensions, and two bedroom units under 45 square meters in total, where the second bedroom usually fits only a bed and a wardrobe
Weight if buying to live in	High, because you feel it every day and cannot change it later
Weight if buying to invest	Medium, though a workable layout rents faster at the same price

Criterion 8, common area fees and the sinking fund

Check point	Detail
What to look at	The common area fee per square meter per month and the one off sinking fund payable at transfer. Condominium common area fees in the market sit roughly between 23 and 75 baht per square meter per month. The main drivers are how much shared facility there is to maintain and how many units share the cost, not the height of the building and not the size of your unit
How to verify it yourself	Convert it into baht per month for the unit you would actually buy. At 50 baht per square meter per month, a 35 square meter unit pays 1,750 baht per month. Then ask how long that rate is fixed and how increases are decided
Warning sign	A fee that looks unusually low against the amount of facility advertised, which often means there is not enough money to maintain it from year three onward. Also ask how late payment interest is calculated, since the Condominium Act caps it at no more than 12 percent per year, and no more than 20 percent per year once payment is 6 months or more overdue
Weight if buying to live in	High, because it is a recurring cost for as long as you own the unit
Weight if buying to invest	High, because it comes straight out of rent and affects net yield every month

Which two extra checks apply only to foreign buyers?

Foreign buyers face two questions Thai buyers never have to ask, and both are decided by the developer rather than by you.

• How much of the 49 percent foreign ownership quota is left in that building. Under Thai law, foreigners may hold freehold title to units representing up to 49 percent of the total unit floor area of a condominium building. Ask the sales office how much of that quota remains and get the answer in writing before you reserve, because a full quota means you would be buying on a leasehold or company structure instead, which changes both your rights and your resale market.
• How the developer handles the paperwork for money transferred from abroad. Freehold purchase by a foreign buyer requires bank evidence that the funds came from overseas, and the sender name and stated purpose must match the name that will appear on the title. Developers that deal with foreign buyers regularly will hand you a written checklist. Ones that do not will leave you to work it out with the bank yourself, which is where transfer dates slip.

There is a third, quieter check worth making. Ask whether the juristic person office will have staff who can handle requests in English after handover. In buildings where the answer is no, foreign owners tend to depend on their agent for years, for everything from utility issues to repair requests. Our guide to buying property in Thailand and the detailed explanation of the quota cover the paperwork side in full.

How do you judge a developer from its finished buildings?

A show unit is built to look its best on the day you visit. What it cannot tell you is how that same work holds up after five years of real use. The most reliable information comes from walking through something this developer has already built and handed over.

Visit the same brand's projects that are 5 to 10 years old

Pick a project the same developer delivered roughly five to ten years ago in a similar price bracket. That age range matters because construction and building system faults have all surfaced by then, while the building is not yet so old that construction standards are no longer comparable.

Look at the parts of the building that need continuous spending, the pool, the gym, the lifts, and the corridors on each floor. Check for water staining on the ceiling outside the lifts, the condition of the grout around the pool, and the noise and speed of the lifts at peak time. Then time an actual lift wait on a weekday morning.

Who to ask, and what to ask, once you are there

The most useful answers come from residents and juristic office staff rather than from sales. Ask how many times the common area fee has risen since handover, what the largest repair job so far was and how long it took to resolve, and which issue co owners raise most often.

If you cannot get inside, work from listing data instead. Count how many sale and rental listings for that project are currently live and read them for problems mentioned repeatedly. PropertyScout has enough condos for rent in Bangkok to compare each developer's older projects within the same area. You can browse the listings.

What warning signs should you catch before paying a reservation fee?

None of these mean the project is bad. They mean you should ask for more documents before any money changes hands.

• The sales office will not let you take the material specification or the draft sale and purchase agreement home to read, saying they can only be viewed on site.
• The reservation form has no refund terms, or has them but does not cover what happens if the project postpones the transfer date.
• The transfer date is written as a broad quarter or year with no penalty clause for late handover.
• The price per square meter sits clearly below the area average with no explanation you can verify, such as the land position or the project size.
• A promotion that requires you to decide within a single day, with the discount tied to paying immediately.
• No information about the juristic person manager or the draft regulations is available at all, even though handover is close.

New build or completed project, which should you choose?

These two options do not differ in quality. They differ in risk and in how much you can verify before paying.

Option	What you can verify and what you trade off
Off plan projects	You get launch pricing and first pick of units, but you cannot inspect anything real and you carry the transfer date risk, so criteria 1 and 6 deserve extra weight
Completed projects with residents	You can walk the shared areas, measure the unit, and talk to residents before deciding, which makes criteria 2, 3, and 4 fully checkable, though launch discounts are gone
Resale units in an existing building	The most verifiable option of the three, since you see the actual unit condition, the fee actually charged, and several years of juristic management history

If you are weighing these three, look at what is actually on the market in each group first. The full Bangkok condo sale listings are on PropertyScout.

Which criteria should you weight more heavily for your goal?

All 8 criteria apply to everyone, but the order should not be the same, because these two groups measure value differently.

If you are buying to live in

Put criteria 2, 3, and 7 at the top, build quality, juristic management, and unit size and layout. These are what you live with daily and what is hardest to change later. Occupancy and resale price still matter, but you can reassess those closer to the day you sell.

The item owner occupiers most often overlook is the common area fee, because attention goes to the monthly mortgage payment and it is easy to forget that the fee runs for as long as you hold the unit and can rise by resolution of the general meeting.

If you are buying to rent out

Put criteria 4, 5, and 8 at the top, occupancy and rental share, resale price, and common area fees. All three feed directly into the return calculation.

For a reference range, the PropertyScout rental yield guide sets the benchmark investors should aim for at 6 to 8 percent per year, while 2026 figures from myproperty.in.th put the Bangkok condo average at roughly 4 to 6 percent per year. Both sets are historical reference points rather than a promise of what you will earn, and should be used only to compare projects against each other.

Frequently asked questions about which condo project is best

Which condo brand is best in Thailand, and whose project should I choose

No single brand suits every location and every budget, and there is no public Thai dataset that ranks developer quality in an auditable way. What works is shortlisting developers with fully delivered projects in your price bracket, visiting one of that brand's projects that is 5 to 10 years old yourself, then comparing two or three shortlisted projects against the same 8 criteria.

Is buying from a smaller developer riskier than buying from a large one

What changes the risk is not company size but the number of projects fully delivered and the record on transfer dates. A smaller developer with several completed projects and no history of postponement is easier to verify than a large one entering that particular market for the first time.

Where can I check a project's EIA status myself

Search the project or developer name in the database of the Office of Natural Resources and Environmental Policy and Planning at eia.onep.go.th. Note that only residential buildings with 80 units or more, or a usable area of 4,000 square meters or more, fall under the requirement. A smaller project is outside the threshold, and that on its own is not a problem.

As a foreigner, what should I ask the developer before reserving

Ask three things in writing. How much of the 49 percent foreign ownership quota remains in that building, what bank documents you will need for funds transferred from abroad and who at the developer helps prepare them, and whether the juristic office will have English speaking staff after handover. Answers given verbally at a sales desk are worth very little at transfer time.

The project is still under construction, what can I check before paying

Four things, without waiting for completion. The developer's record of delivered projects, the EIA status and construction permit, the written material specification, and the refund terms and transfer date stated in the reservation form and draft sale and purchase agreement. You should have all four before the first payment.

Summary

The question of which condo project is best is answered best by dropping the search for the right brand name and instead applying one set of criteria to every project on your shortlist. Start with the first three, delivery record, build quality visible in older buildings, and juristic management, then work through all 8.

Once you have a shortlist that passes, the next step is seeing what is actually available. Browse verified listings on PropertyScout, which is free for buyers and tenants, with property consultants who can arrange viewings and check documents with you from the first day.
