47 red flags to catch before you sign a lease.
Renting an apartment in Thailand from anywhere — Berlin, Bangkok, or Bangalore — fails for the same reasons. Listing photos hide too much, conversation tactics vary in honesty, and Thai-specific things (TM30, mosque proximity, fiber lottery) catch out even seasoned travelers. This is the actual 47-point methodology our scouts use on the ground when they verify a listing before a customer signs. Use it yourself, or send us the listing and we'll do the on-site work for you.

Thai rental markets reward speed and punish caution. The good listings move in days. The dishonest ones use the same urgency to push deposits before viewing. Both ends of the market feel similar from your laptop in Berlin or your hotel in Chiang Mai — and that asymmetry is where mistakes happen.
We've been on the ground in Bangkok, Koh Samui, Koh Phangan, and Phuket since launch. This list is what our scouts actually carry when they walk into a property: every red flag worth checking before you wire a deposit. Self-serve version — fully usable without us.
If you read this and decide you'd rather have a vetted local on the ground for your specific listing, that's exactly what we do. Otherwise: take this checklist with you.
There are five stages where things break down:
47 items total. Most apply to most listings. Don't expect to tick all of them perfectly — flag any four or more in a single listing as a hard pass.
Section 1 · 15 items
What you can verify from screenshots and a careful read, before any conversation.
If a 1-bedroom in central Sukhumvit is ฿8,000/month when comparable listings are ฿18,000+, the price is bait. Either the unit isn't real, the photos aren't of that unit, or there's a hidden cost (utility flat-rate, mandatory cleaning fee, key money) the listing doesn't mention.
Most modern listings have year-recent photos. If photos look 2018-era (older décor, low resolution, dated color treatment), the unit may have been re-let many times since with no fresh photography. Reverse-image search them via TinEye or Google Lens.
Real-estate photographers use 14–16mm lenses to make rooms look 30% larger than they are. If furniture looks cartoonishly stretched at the edges, mentally subtract a third of the apparent space.
No charger cables, no kitchen utensils, no toothpaste — that's either a model unit (the actual rental looks different) or photoshopped staging.
If the listing claims renovation but only shows finished shots, ask for one undated photo of the bathroom or kitchen with daylight visible. If they refuse, the renovation is older than claimed.
"Near BTS Asok" can mean a 3-minute walk or a 25-minute soi trek. Specific street name matters; specific building name matters more. Vague addresses are a control mechanism so you can't pre-research the area.
Even rough hand-drawn plans cost the agent nothing. Their absence usually means the agent has never been to the unit.
A "queen-size" bed in a photo where it touches both walls means the room is much smaller than advertised. Always check whether claimed dimensions are consistent with visible furniture.
Reverse-image search every photo. Stock photos repurposed across multiple Facebook, Renthub, or DDProperty listings = scam aggregator account.
If the agent shows you only the inside, you have no idea whether the building is well-maintained, what the neighborhood smells like, or whether construction is happening 30 metres away.
Same unit on Airbnb, Renthub, Facebook Marketplace, and a Thai-language site with three different monthly rates is a sign the agent is fishing — they'll quote whichever rate the inquirer seems willing to pay.
Color-graded photos with crushed shadows hide everything in dark areas. AC unit on the wall? Mold around the windows? Cables running across the floor? You can't see them.
Thai short-term and serviced apartments usually have 1–3 month lead times. Suspiciously instant availability often means high turnover — usually because of noise, neighbors, or building issues.
A common trick to hide lack of natural light or unflattering window views. Always ask for one daylight photo with curtains open before you commit.
Easy to fake an interior; harder to fake the lobby. Ask for a 30-second walk-in video from the lift to the unit door — if they refuse, walk away.

How a landlord or agent communicates before money moves is the strongest predictor of how they'll behave after.
Anyone with a real listing and a phone can do a quick FaceTime/WhatsApp video walkthrough. Refusal means either (a) the unit doesn't match the photos, (b) the agent isn't actually the agent, or (c) the building isn't what's described.
Some demand is real, but if every conversation includes urgency tactics ("the family from Switzerland is coming tomorrow"), it's a scarcity script. Real Bangkok agents are usually quite chill about timeline.
Modern Thai property management uses bank transfer with a written receipt. A demand for cash, especially USD or EUR, is straightforward fraud insurance: if you're never given a receipt, you can never prove you paid.
"Send 1 month deposit to hold the unit, then we'll show it to you" is a recurring scam template. Never pay before you, or someone you trust, has been inside.
If the listing is by "Sarah at SamuiLife" and the WhatsApp account is "Niwat" with a profile pic that doesn't match, the listing has been re-syndicated by a third party who may not actually have access to the unit.
Monthly rent, deposit amount, utility cost handling, length of lease — these should all be confirmable in a WhatsApp message before any money moves. A landlord who only confirms by phone is creating deniability.
Some agents prefer their office for paperwork. Fine. But if they refuse a final at-property meet before signing, ask why. Often the answer is that they don't actually have keys, or the building requires registered tenants only.
Ask the rent twice, three days apart. Ask "is electricity included?" twice in different ways. Honest counterparts give the same answer; dishonest ones drift.

What to check when you (or your scout) is physically inside the unit.
Look up — yellow/red Thai construction permit boards (with the building diagram and dates) are visible from 100m+. A construction site within earshot will subject you to 7am–5pm pile-driving for the lease term, six days a week.
Mosques perform the call to prayer 5×/day, the first one (Fajr) before dawn. Buddhist temples chant in early morning. Schools have outdoor PA systems. None are deal-breakers per se — but you must know.
Check ceilings under bathrooms one floor up; check windowsills facing south or southwest (heaviest rain exposure). Mold remediation is the landlord's problem in theory, your problem in practice.
Step into the room, close the door, turn the AC on, stand still for 60 seconds. If it rattles, hisses, or smells musty, it'll cost you sleep. AC units older than 8 years are also energy-inefficient — your electricity bill will reflect it.
Most Thai apartments are not sound-rated. A loose window seal lets in traffic noise, neighbors' AC condensers, and (if you're high up) construction noise from blocks away. Test by putting your ear close to the closed window — should be near-silent.
Run the shower at full blast for 90 seconds. Pressure should not drop. Hot water should arrive within 20 seconds. Fill the bathroom and kitchen sinks — drains that bubble or smell are a plumbing system problem.
Count working outlets per room. If the breaker box is still old-style (toggles, no labels in English/Thai), wiring is likely 30+ years old. Loose-feeling outlets with browning around the holes have had heat events — a fire risk.
Visit at 11pm if you can. Is the main door secured? Is there a 24-hour guard, or a code lock? Are the lifts working? Many older Bangkok buildings have one lift, which fails monthly — your 8th-floor unit becomes a daily climb.

Standard-looking clauses that aren't, in Thai context.
Thai law generally entitles the tenant to deposit return at end of lease minus documented damage. Wording that gives the landlord blanket discretion is a red flag — and increasingly common.
Thai standard is 12-month with a 2-month break clause if you give notice. Some landlords now insert "early termination = forfeiture of deposit + 3 months rent." Don't sign that.
"Electricity ฿10/unit, water ฿20/unit" sounds reasonable until you realize Thai utilities cost ฿4/unit and ฿8/unit. A 2.5× markup is common in Bangkok serviced apartments. Negotiate metered billing where possible.
TM30 is the legally required notification of foreign tenant residency to immigration. Either the landlord does it within 24h of arrival (right) or you do (and need their cooperation, building plans, lease copy — a hassle). Get this clarified in writing.
"Tenant may be evicted at landlord's discretion for breach of community standards" with no enumerated standards = landlord can evict you anytime. Insist on a numbered list of evictable offenses.
Who pays for AC repair? Plumbing? Roof leak? Thai law has defaults, but practice varies wildly. Get specific in the lease.
Some leases auto-renew for another 12 months unless you give 90+ days notice. If you're a digital nomad, you may not know your plans 90 days out — push for shorter notice or no auto-renew.
฿500/day for late rent + 10%/month interest is common. Negotiate down to a flat 5% one-time fee. If a landlord won't move on this, they're optimizing for fee revenue, not tenancy.
Section 5 · 8 items
Things you can't Google because the relevant context is local and unwritten.
There are ~4,000 mosques in Thailand, many in central Bangkok neighborhoods (Pratunam, Ramkhamhaeng) and most beach destinations. The first call (Fajr at ~5am) is loud and consistent. Search "mosque near {address}" within a 500m radius before you rent.
Sukhumvit Soi 31–55, parts of Sathorn, and most of the western canal districts flood in monsoon (June–October). A ground-floor or basement-level unit may take on water annually. Ask the landlord directly: "Has this unit ever flooded?" — and watch the answer carefully.
"WiFi included" can mean (a) you have your own AIS Fiber/3BB connection (good — usually 300+ Mbps), or (b) you share a single building line with 30 other units, peak-hour speeds collapse to <5 Mbps, and the IP addresses are landlord-controlled (no VPN, no servers, unreliable remote work). Ask explicitly.
Indoor coverage varies dramatically by carrier and neighborhood. AIS dominates in central Bangkok, True in Phuket and Samui, DTAC in older Bangkok suburbs. If you're a remote worker, you need a backup mobile hotspot — which one depends on where you're renting.
A property on a Soi (small side street, e.g. "Sukhumvit Soi 21") is typically 10–15 dB quieter than the same property on a Thanon (main road, e.g. "Sukhumvit Road"). A Soi 21 unit at the entrance is loud; one at the dead-end is silent.
Thai law requires construction sites to post a yellow board with permit number, contractor name, and start/end dates. Walk a 200m radius around your prospective building. Boards with end dates more than 12 months out = ongoing noise for your entire lease.
Foreign residents must register their address with Thai immigration. Your landlord's TM30 filing is the foundation — without it, your 90-day reports get rejected and you risk overstay fines. Verify the landlord understands and will file TM30 within 24h of move-in.
Thailand has many "newly built" buildings whose construction was paused 5–8 years ago and only recently completed. The unit is genuinely new, but the structure is older — meaning settling cracks, dated electrical, and aging waterproofing are already in play. Look at the building's overall age, not the unit's.
If you can be in Thailand for the visit-stage items (24–31), use a Sunday afternoon and be thorough. If you can't, you have three options:
If you've already found a listing and want it verified, submit it here. Three pricing tiers from $49 to $199. We earn the same whether the apartment passes or fails — which is the point.
A scout visit takes 60–90 minutes. The structured report is delivered within 48 hours of the visit. The bottleneck is usually landlord availability for the viewing — not the verification itself.
Yes. You're paying for the verification, not for finding a problem. A clean report is the most useful possible result for someone signing from abroad: it tells you the listing is what it claims to be.
We're currently launching in Bangkok, Koh Samui, Koh Phangan, and Phuket. Other cities and islands on request — email hello@truspot.io.
No. We're independent by design and earn the same fee whether we recommend signing or walking away. No commissions, no kickbacks.
Yes — drop your email in the form on this page and we'll send you a link to a clean print-friendly version you can save as PDF.
