You found a condo you love near Thong Lo BTS. The views are great, the pool looks incredible, and the landlord seems friendly. Now there's a contract sitting in front of you, and you're about to sign it with barely a glance. Stop right there. I've seen too many renters in Bangkok get burned by overlooking simple details in their lease agreements. Here are 10 things you absolutely need to check before you put pen to paper.

1. The Deposit and What Happens to It

Most Bangkok condos require a two month security deposit plus one month's rent upfront. That means if you're renting a one bedroom at The Lumpini 24 near Phrom Phong BTS for 25,000 THB per month, you're handing over 75,000 THB on day one. That's real money.

Check exactly what conditions must be met for your deposit to be returned. Some contracts have vague language about "wear and tear" that landlords later use to deduct for scuffed walls or a slightly stained sofa cushion. Get the move in condition documented with photos and make sure the contract states a clear timeline for deposit return, ideally within 30 days of moving out.

2. The Lease Term, Break Clause, and Early Termination Penalties

Standard Bangkok leases run 12 months. But what happens if your company relocates you after six months? Or what if the construction noise from the new condo project on Sukhumvit Soi 39 makes your unit unlivable?

Look for an early termination clause. Many contracts will state that leaving early means forfeiting your entire deposit. Some landlords will negotiate a 30 day notice period with a one month penalty instead. If you're an expat on an uncertain contract, push for a diplomatic clause that lets you break the lease with 60 days notice if you leave Thailand. Get it in writing before you sign.

I once met a teacher renting near Ari BTS who lost 40,000 THB because her contract had zero flexibility and her school didn't renew. Don't let that be you.

3. What's Actually Included in the Rent

This one trips people up constantly. Your 18,000 THB per month studio at Ideo Mobi Rama 9 near Phra Ram 9 MRT might seem like a steal until you realize electricity is billed at 8 THB per unit instead of the government rate of around 4 THB. That inflated electricity rate is extremely common in Bangkok condos, especially when renting from individual landlords.

Check whether the rent includes common area maintenance fees. In most cases the landlord covers this, but some contracts sneakily pass it to the tenant. Also confirm who pays for internet installation, water charges, and any parking fees. A condo near Sala Daeng BTS might charge 3,000 to 5,000 THB per month for a parking spot on top of rent.

Get a full breakdown of every monthly cost. Write it into an appendix attached to the contract if you need to.

4. Appliance Condition and Maintenance Responsibilities

That fancy washing machine and the air conditioning units in your new place at Life Asoke Hype near Rama 9 MRT might look fine now. But what happens when the AC starts leaking three months into your lease?

Your contract should clearly state who is responsible for repairs. The general rule in Bangkok is that landlords handle major appliance breakdowns and structural issues while tenants cover minor fixes. But "major" and "minor" mean different things to different people. I've seen landlords refuse to fix a broken water heater because they claimed it was the tenant's responsibility.

Before signing, test every appliance in the unit. Run the AC, flush the toilets, check water pressure, open every cabinet. List every existing scratch, dent, and malfunction in a signed inventory sheet attached to the contract.

5. Subletting, Guests, and Renovation Rules

Planning to have your partner move in later? Thinking about listing a spare room on Airbnb? Most Bangkok condo contracts explicitly prohibit subletting, and many juristic offices have strict rules about short term guests and visitor registration.

A friend renting a two bedroom unit at Aspire Sukhumvit 48 near Phra Khanong BTS got a warning from building management because his girlfriend stayed over too frequently without being registered. The juristic office threatened to fine the landlord, who then pressured my friend to pay up.

Also check if you're allowed to make any changes to the unit. Even hanging shelves or adding a curtain rod can become a dispute if the contract prohibits modifications without written landlord approval.

These ten points might seem like a lot of homework, but spending an extra hour reviewing your contract can save you tens of thousands of baht and months of frustration. Bangkok's rental market moves fast and landlords often prefer tenants who sign quickly. Don't let urgency push you into a bad deal. Read every clause, ask questions, and negotiate the terms that matter most to your situation.
