After helping over a thousand expats find condos across Bangkok, we've seen the same rental mistakes come up again and again. Some cost people a few thousand baht. Others cost them months of frustration, broken leases, or apartments they regret signing for. The good news is that nearly all of these mistakes are completely avoidable once you know what to watch for.

Whether you're moving to Bangkok for the first time or switching condos after a lease ends, here are the most common traps renters fall into, and how to sidestep every single one of them.

Overpaying Because You Didn't Check the Building's Real Market Rate

This is the number one mistake we see, and it happens constantly. A landlord lists a one bedroom at Life Asoke Hype near MRT Phetchaburi for 22,000 THB per month. Sounds reasonable for a newer building near the city center, right? But if you checked other units in the same building, you'd find similar units going for 16,000 to 18,000 THB. That's a gap of up to 6,000 baht every single month.

Landlords in Bangkok price units based on what they think they can get, not based on a standardized system. Two identical units on different floors of the same condo can have wildly different asking prices. Always compare at least three to five listings in the same building before you commit.

The fix is simple. Search for the building name specifically, look at recent transactions, and don't be afraid to negotiate. Most landlords expect it. If you're offering a 12 month lease, you have more leverage than you think.

Signing a Lease Without Understanding the Move Out Penalties

Here's a scenario that plays out every month in Bangkok. A marketing professional signs a 12 month lease for a studio at Ideo Mobi Sukhumvit 66 near BTS Udom Suk at 12,000 THB per month. Four months in, their company relocates them to Silom. They want to break the lease, and that's when they discover the contract says they lose their entire two month deposit, plus owe an additional month's rent as a penalty.

Thai rental contracts heavily favor landlords, and most expats sign without reading the fine print. Some contracts include clauses that prevent you from subletting, require 60 to 90 days written notice, or charge cleaning fees that eat into your deposit regardless of the unit's condition.

Before you sign anything, read every clause about early termination, deposit deductions, and notice periods. If your Thai isn't strong, ask for an English version or have someone you trust review it. This step alone can save you 30,000 to 50,000 THB in worst case scenarios.

Choosing Location Based on Nightlife Instead of Your Daily Commute

We get it. You visited Bangkok on vacation, loved the energy around Nana or Thong Lor, and decided that's where you want to live. But there's a big difference between spending a weekend on Sukhumvit Soi 11 and commuting from there to your office near Lumpini every single morning.

One of the most common regrets we hear is from renters who prioritized neighborhood vibe over practical daily logistics. A teacher working in Bang Na who rents in Ari because it feels trendy is looking at 45 to 60 minutes each way on the BTS during rush hour. That's almost two hours a day lost to commuting.

Map out where you'll actually spend your weekday mornings and evenings. Check Google Maps during rush hour, not on a Sunday afternoon. Sometimes the smartest move is picking a less glamorous station like Punnawithi or Bearing, where a modern one bedroom runs 10,000 to 14,000 THB, and your commute drops to 15 minutes.

Skipping the In Person Walkthrough Before Paying Anything

Bangkok's rental listing photos can be incredibly misleading. We've seen units at The Base Park West near BTS On Nut photographed with wide angle lenses that make a 28 sqm studio look like a sprawling suite. Then you show up and realize the "living area" barely fits a sofa.

Beyond size distortion, photos hide problems like mold in bathrooms, broken air conditioning units, noisy construction next door, or a view that faces directly into another building's parking garage. One renter told us they signed a lease remotely for a unit on Soi Ratchadaphisek 36 and arrived to discover the building's elevator had been broken for two weeks with no repair date in sight.

Always visit in person. Walk through the unit, test the water pressure, check the AC, open every closet, and look out every window. Visit at different times of day if you can. A quiet condo at 2 PM can turn into a bass thumping nightmare at 10 PM if there's a rooftop bar nearby.

Not Documenting the Unit's Condition at Check In

Your deposit is typically two months' rent. For a 20,000 THB unit, that's 40,000 THB sitting in your landlord's hands. And the single best way to protect it is something most renters skip entirely: a thorough condition report with photos on the day you move in.

Take pictures of every scratch, stain, dent, and scuff mark. Photograph the condition of appliances, curtains, and furniture. Send these photos to your landlord via email or LINE with a written note confirming the existing condition. If they push back at move out and claim you damaged something that was already worn, you'll have timestamped evidence.

A renter at Lumpini Suite Phetchaburi near MRT Makkasan lost 15,000 THB from their deposit over a stained sofa cushion that was already there when they moved in. They had no photos to prove it. Don't let that be you.

Renting in Bangkok doesn't have to be stressful or expensive if you avoid the mistakes that trip up so many people before you. Do your research on pricing, read your lease carefully, choose location based on real life logistics, always visit in person, and document everything from day one. These five habits will save you money, time, and headaches throughout your stay.
