Expert take — Cost of Asia editorial team Budgets built on visa exemptions stopped working on 15 September 2026, when Thailand cut visa-free stays to 30 days for tourism only and capped land-border exempt entries at two per calendar year. Living on exemptions now means leaving every 30 days, mostly by air. Price the visa you will actually use, such as the DTV with its 500,000-baht funds requirement, before you sign a lease.
Most people moving to Thailand get rent, food and transport roughly right. The money leaks through rules and fees that cost-of-living tables miss. This page is for anyone staying six months or more.

At a glance
| Best to avoid if you… | Mistake | Why it costs |
|---|---|---|
| Plan to stay over a month | Relying on exemptions and border runs | 30-day stays, two land entries a year |
| Are renting a condo | Forgetting move-in cash | About three months' rent on signing |
| Run air conditioning | Ignoring the electricity rate | Landlord rates can be nearly double the utility's |
| Use a foreign card | Paying ATM fees every week | 220 baht per withdrawal |
| Are buying insurance | Buying for the visa, not the hospital | Compliant plans can carry big deductibles |
How we chose
- Costs that standard monthly budgets, including our own calculator, leave out
- Each backed by a published source: embassies, regional trade press, rental and money guides
- Recent rule changes weighted more heavily
Our budget calculator example uses a $1,800 monthly base with a 15% buffer, and states that deposits, taxes and visa conditions are not included. That is where the mistakes below sit. Checked on 31 October 2026.
1. Relying on visa exemptions and border runs
Since 15 September 2026, TTG Asia reports, the visa exemption is 30 days for 60 countries and territories, covers tourism only, and land-border exempt entries are limited to two per calendar year (with exceptions for some ASEAN nationals). The old pattern of living on exemptions plus border runs no longer adds up.
Compare it with a long-stay visa. The Royal Thai Embassy in Budapest lists the DTV at 500,000 baht in proof of funds, valid for five years with up to 180 days per entry, and a fee of 350 euros there (fees vary by embassy). It doesn't allow work for Thai employers or Thai clients. See our Thailand visa requirements page for other routes.
2. Forgetting move-in cash
Thaiger's lease guide puts typical Bangkok upfront costs at a two-month security deposit plus the first month's rent, about three months' rent on signing. PropertyScout says this two-plus-one pattern is market convention, not law. Deposits typically come back around 30 days after you leave, per Thaiger.
With an illustrative rent of 20,000 baht a month, that is 60,000 baht before furniture or a scooter. Thaiger also warns that without a break clause you can lose the full deposit if you leave early. Ask for one allowing exit after about six months with 30 days' notice.
3. Ignoring the electricity rate
Thaiger puts the MEA government rate at about 4.00 to 4.18 baht per unit in 2026, while many Bangkok landlords charge 7 to 8 baht or more. On an air-conditioned condo, it estimates the gap at around 10,000 baht over a year. PropertyScout notes a 2025 notification caps bulk-billed electricity at 4.88 baht per unit, but only for landlords who count as a controlled business (several units).
Ask for the rate in writing, and whether the unit has its own meter.
What would this move really cost you?
Use your own rent, insurance, transport and visa assumptions. Compare options before committing.
4. Paying ATM fees every week
Thailand Starter Kit says most Thai ATMs charge 220 baht per withdrawal on foreign cards, checked in September 2026, with AEON machines at 150 baht. Your home bank may add its own charge. Withdraw weekly for a year and the Thai fee alone is 52 × 220 = 11,440 baht.
Decline offers to charge you in your home currency; that dynamic currency conversion uses a worse rate. A cheaper transfer route is covered in our money services guide.
5. Buying insurance for the visa, not the hospital
Requirements differ by visa. Thaiger lists 3,000,000 baht of cover for the O-A retirement visa, 40,000 baht outpatient and 400,000 baht inpatient for the O-X, and none for a Non-O retirement extension. It also says travel insurance doesn't satisfy any visa requirement.
The trap is that the cheapest compliant policies often have very large deductibles, so they tick the visa box while leaving most of a hospital bill to you. Budget for the cover you need, then check it also meets the visa rule.
What to check before you decide
- Price your visa route, including fees and funds you must keep in the bank.
- Put deposit cash in a separate line from your emergency reserve.
- Get the electricity and water rates written into the lease.
- Confirm your landlord will file the TM30 report within 24 hours, which Thaiger says affects later visa extensions.
- Plan how you will move money into Thailand, and read about the 2024 foreign-income rule in our Thailand tax mistakes guide.
FAQ
Can I still do border runs in Thailand?
Only within limits. Since 15 September 2026, exempt entries over land are capped at two per calendar year, and each stay is 30 days for tourism. For a longer stay, get a visa before you travel.
How much cash do I need to rent in Bangkok?
Typically about three months' rent at signing: a two-month deposit plus the first month. Add furniture and setup costs if the unit is unfurnished.
Is health insurance mandatory in Thailand?
It depends on the visa. The O-A and O-X retirement visas require set amounts; a Non-O retirement extension doesn't. Check your visa's rule, then buy for your real medical risk.
