Learn › Buying a home in Norway

In short: As of 2026 you normally need at least 10% of the price as your own equity (the mortgage is capped at 90% of value), and your total debt cannot exceed 5 times your gross annual income. On most resale homes you also pay a one-off document tax (dokumentavgift) of 2.5% of the price, plus registration fees, and some municipalities add an annual property tax (eiendomsskatt).

Buying a home in Norway: what it costs and how the rules work

Kontoo editorial team · Updated 06/24/2026 · 7 min read

Buying a home in Norway means more than the asking price. A regulated mortgage (boliglån) sets how much you can borrow, a one-off document tax (dokumentavgift) of 2.5% applies to most resale homes, and some municipalities charge an annual property tax (eiendomsskatt). This lesson walks through the main rules and a worked example in Norwegian kroner (NOK). It is educational background, not financial advice — figures change, so confirm current numbers with the official sources before you commit.

Work out your budget. Norway’s lending regulation (utlånsforskriften) caps total borrowing at 5 times gross annual income and the mortgage at 90% of the home’s value, so you generally need at least 10% as equity (egenkapital).
Save the equity and the buying costs. On top of the deposit, budget for the document tax and registration fees, which are billed soon after the purchase is registered.
Get a financing certificate (finansieringsbevis) from a bank, then bid. Norwegian sales are usually open bidding rounds, and a winning bid is legally binding.
After completion, the transfer is registered with Kartverket; you then pay the document tax and any annual municipal property tax that applies where you bought.

What matters

Norway’s housing market runs on a regulated mortgage (boliglån) and a transparent, fast-moving bidding process. Two national limits shape how much you can spend. First, a loan-to-value cap: a bank can lend at most 90% of the home’s value, so you generally bring at least 10% as your own equity (egenkapital). This minimum equity was reduced from 15% to 10% with effect from 1 January 2025. Second, a debt-to-income cap: your total debt — including the new mortgage, car loans and other credit — may not exceed 5 times your gross annual income. The rules also assume you could still service the loan if interest rates rose. Banks have a small quota to lend outside these limits, so they are firm guidelines rather than absolutes. The big one-off cost when you buy is the document tax (dokumentavgift): 2.5% of the property’s market value, due when the transfer is registered with the land registry, Kartverket. There is an important nuance for new builds: when you buy a newly built home directly from the developer before it has been taken into use, the 2.5% is generally charged only on the plot/land value, not on the building — which usually makes it far smaller than on an equivalent resale home. Cooperative housing (borettslag) is exempt because ownership is transferred as a share, not a registered deed. On top of the document tax you pay registration fees (tinglysingsgebyr) for the deed and the mortgage, billed shortly after registration with a short payment deadline. After you own the home, the main recurring public charge is municipal property tax (eiendomsskatt). This is optional: each municipality decides whether to levy it. Most Norwegian municipalities did so in 2025, but a number did not, so it is worth checking the specific place you buy. For homes the rate is capped at 4 per mille (0.4%) of the assessed value, and a municipality can only change its rate gradually. The assessed value is often lower than the market price, so the actual bill is usually a modest annual amount rather than a percentage of the full purchase price.

ExampleA worked example for a resale home priced at 4,000,000 NOK (rounded, as of 2026). With the 10% minimum equity, you need about 400,000 NOK of your own money and the bank lends up to 3,600,000 NOK. The document tax is 2.5% of 4,000,000 = 100,000 NOK, plus a few thousand kroner in registration fees. So before furnishing you need roughly 400,000 + 100,000 ≈ 500,000 NOK in cash on top of the mortgage. If the same home were a brand-new build with a plot value of, say, 1,000,000 NOK, the document tax would be 2.5% of 1,000,000 = 25,000 NOK instead — about 75,000 NOK less. If the municipality levies the maximum 4 per mille property tax on an assessed value of 2,500,000 NOK, that is 10,000 NOK per year. (Illustrative, rounded figures — verify current rates with the official sources.)

In depth

How the lending regulation works in practice

The lending regulation (utlånsforskriften) combines several limits: a maximum 90% loan-to-value, a total-debt ceiling of 5 times gross annual income, a requirement that you could cope with higher interest rates, and minimum repayment for highly leveraged loans. Banks may approve a small share of loans that breach these limits, which gives some flexibility for strong borrowers. The 10% equity floor since 1 January 2025 made entry slightly easier, but the 5x-income cap is often the tighter constraint in expensive areas like Oslo.

One-off buying costs versus ongoing costs

It helps to separate the two. One-off costs at purchase are your equity, the 2.5% document tax (much smaller on new builds), and registration fees — together often a meaningful sum that must be cash, not borrowed. Ongoing costs are the monthly mortgage payment, any shared/condo fees (felleskostnader), insurance, maintenance, and — where it applies — annual municipal property tax. Mapping both sides before bidding stops the document tax and first-year charges from becoming a surprise.

Checklist

The mortgage is capped at 90% of value, so you generally need at least 10% equity (lowered from 15% on 1 January 2025).
Total debt cannot exceed 5 times your gross annual income.
Document tax (dokumentavgift) is 2.5% of value on most resale homes; new builds usually pay it only on the plot value.
Property tax (eiendomsskatt) is optional per municipality, capped at 4 per mille (0.4%) of assessed value for homes.

Common myths

Myth: You always need 15% equity to buy in Norway.

Reality: The minimum was lowered from 15% to 10% with effect from 1 January 2025, so the cap is now a 90% loan-to-value (at least 10% equity). Banks may still ask for more in individual cases, and the 5x-income debt limit can bind first. (As of 2026 — confirm at finanstilsynet.no.)

Myth: Everyone pays 2.5% document tax on a new-build home.

Reality: For a newly built home bought directly from the developer before it is taken into use, the 2.5% is generally calculated only on the land/plot value, not the building. Cooperative (borettslag) flats pay none. So the cost varies a lot by purchase type. (As of 2026 — see kartverket.no.)

Frequently asked questions

How much equity do I need to buy a home in Norway?

Under the lending regulation, banks can lend at most 90% of the home’s value, so you generally need at least 10% as equity. This minimum was lowered from 15% to 10% on 1 January 2025. Separately, your total debt may not exceed 5 times your gross annual income. Banks can grant a limited share of loans outside these limits, and some borrowers still need more equity in practice. (As of 2026 — check finanstilsynet.no when in doubt.)

Do I always pay the 2.5% document tax?

Most resale homes pay dokumentavgift of 2.5% of the market value at registration. For a brand-new home bought directly from the developer (not yet taken into use), the tax is generally calculated only on the land/plot value, not the building — which usually makes it much smaller. Cooperative (borettslag) flats are exempt because no deed is registered. (As of 2026 — see kartverket.no.)

Will I pay annual property tax?

It depends on the municipality. Property tax (eiendomsskatt) is optional and decided locally; most Norwegian municipalities levied it in 2025, but some do not. For homes the rate can be at most 4 per mille (0.4%) of the assessed value, and the assessment is often below market value. Check your specific municipality. (As of 2026 — see skatteetaten.no.)
