What You Need to Know About Thailand Before You Move

Thailand has the deepest long-stay infrastructure in the region. More foreigners have lived there longer, which means more established routes for almost everything — healthcare, housing, schooling, visas, community.

That maturity is the main reason to choose it, and it comes with a corresponding cost: Thailand is generally more expensive than Vietnam for a comparable standard of living.

Who Thailand suits

It suits people who want established systems rather than improvisation: retirees, families, anyone with ongoing medical needs, and people who value a mature international community.

It also suits people who want genuine choice of environment. Bangkok, Chiang Mai, the islands and the coastal cities are meaningfully different places to live, not variations on a theme.

The visa landscape

Thailand’s defining characteristic here is that it has more defined long-stay routes than most of its neighbours — categories built around retirement, education, work, investment and long-stay programmes.

Two practical points:

• Choosing the right category matters more than the paperwork. The routes have genuinely different requirements, costs and obligations. Picking wrong is the expensive mistake, not filing wrong.
• Reporting obligations continue after arrival. Several routes carry ongoing requirements — periodic reporting, address registration, renewal windows. Plan for the maintenance, not just the application.

Specifics change and vary by nationality and category, so treat any summary — this one included — as orientation and confirm the current requirements officially.

What it costs

Location drives everything.

Bangkok spans the widest range: you can live modestly or very expensively, and central condo rent is the main variable.

Chiang Mai is consistently the most affordable of the main bases, with a well-established remote-work community. The trade-off is the annual burning season, when air quality deteriorates significantly for a period — a real consideration, particularly with respiratory conditions or children.

Islands and coastal cities run higher for groceries, imports and housing, and are more seasonal in both price and atmosphere.

Pattaya sits lower than Bangkok with strong coastal infrastructure and a large established foreign-resident population.

Broadly, expect Thailand to run somewhat above equivalent Vietnamese cities — the gap is narrowest in Chiang Mai and widest in central Bangkok and the resort islands.

Healthcare

This is Thailand’s strongest practical advantage. Its private hospital system is among the best in the region, with international-standard facilities, English-speaking specialists and a long history of treating foreign residents.

For anyone weighting healthcare heavily — older movers, families, ongoing conditions — this is frequently the deciding factor over neighbouring countries. Carry proper international insurance regardless; quality and cost are different questions.

Banking and money

Card and QR payment are widely established. Opening a bank account as a foreigner is possible and is generally tied to your visa category, so the route you choose affects how straightforward it is.

Internet and working remotely

Reliable and fast in the main centres, with mature coworking — especially in Chiang Mai and Bangkok. Island connectivity is more variable; if you work remotely from one, verify the specific property rather than trusting a general reputation.

The honest trade-off

Thailand costs more and gives you more established infrastructure. Vietnam costs less and is changing faster. Neither is the better answer in the abstract — it depends on whether you are optimising for cost or for certainty.
