What Owning a Korean Home Costs Every Year

The costs of buying a home in Korea split cleanly into two groups, and almost everyone budgets for the wrong one.

The transaction costs — acquisition tax, agent, scrivener, the bond — are large, visible, and paid once. They are also already covered in detail.

This is the other group: the costs that arrive every year for as long as you own the property. Over a ten-year hold they are the larger number, and they are the ones a rent-versus-mortgage comparison leaves out entirely.

1. Acquisition tax: establish which schedule applies before quoting a rate

“Acquisition tax in Korea is 1.1% to 12%” is a sentence that appears everywhere and describes nothing. It runs two entirely separate structures together.

The ordinary schedule, for buying a home for consideration:

Local education tax sits on top, and rural special tax where the conditions apply, so the effective burden typically lands somewhere around 1.1% to 3.5%. Tracked here.

The heavy rates are something else. Article 13-2 of the Local Tax Act applies 8% or 12% to certain acquisitions of additional homes in adjusted areas, high-count acquisitions outside them, and acquisitions by companies.

2. Property tax arrives every year regardless

Property tax is a local tax on the ownership itself. It does not depend on any national threshold and it does not go away.

It is the floor of the annual cost, and for most owners it is the whole of the tax line — because the second tax below only starts above a threshold most homes do not reach.

3. The holding tax has an allowance, and it is two numbers

The comprehensive real estate holding tax works on the aggregate published price of all housing held.

From that, a deduction of ₩900,000,000 — or ₩1,200,000,000 for a single-home household is applied. What remains is multiplied by a fair market value ratio set by decree to reach the tax base.

For an individual holding two homes or fewer, the rate on the housing portion is progressive from 0.5% to 2.7% by tax base.

4. Repairs stop being someone else’s problem

A tenant’s management bill and an owner’s are not the same document, even in the same apartment.

The long-term repair reserve funds replacement and repair of the building’s major systems, and the owner bears it. A tenant who paid it through the management bill can reclaim it from the owner when the lease ends.

Once you own the property, there is nobody to reclaim it from. It is simply a cost.

The same shift applies to everything inside the unit. Boiler, appliances, flooring, sanitaryware, the interior itself — a tenant raises these with the landlord, and an owner replaces them on their own schedule with their own money.

So a projection built from your own past management bills is missing two things: the reserve you used to get back, and the replacements you used to ask someone else to make.

5. Health insurance: a real factor, and not an automatic one

Property can enter the premium assessment for a locally insured person, so buying a home can affect what a locally insured household pays.

But the sentence that gets written — “buying a home means losing dependant status” — is not right, and putting it into a cost model as a fixed line is worse than leaving it out.

Dependant status turns on its own income and property tests, and whether a purchase changes your position depends on your insurance category and on your own figures against those tests. It is a question to answer about yourself, not a consequence to assume. The tests are set out in NHIS dependants: the income and property tests.

6. Interest is a cost. Principal is not.

Mortgage interest belongs in the annual cost line, in full.

Principal repayment does not. Paying down a loan converts cash into equity — it reduces a liability rather than consuming money, and it comes back to you when the property is sold. Counting it as a housing cost is the single most common error in these comparisons, and it makes owning look more expensive than it is.

The opposite error is more common still, and it is on the other side of the ledger: forgetting that the equity itself has a cost.

What an annual cost line actually contains

Note the shape of it. Of the eight rows, one is paid once, one is not a cost at all, and the largest never appears on a statement.

Which is why the question “is buying cheaper than renting” cannot be answered by comparing a rent figure with a mortgage payment. It needs the same capital priced the same way on both sides, over a stated number of years.
