Is buy-to-let property profitable in Oslo now?

Has Oslo become a better buy-to-let market lately?

Oslo buy-to-let looks better than it did a few years ago, but the average deal still does not produce an attractive return with a normal mortgage.

The improvement is real. According to Eiendom Norge, Oslo rents rose another 3.6% in the second quarter of 2026 and were 4.7% higher than a year earlier. Rental prices across Norway's four largest cities have now climbed about 32% since early 2022, far more than consumer prices over the same period.

At the same time, Oslo house prices have been unusually weak. Prices fell about 0.8% over the first seven months of 2026 while Norwegian prices overall continued rising. Even after the strong national rebound in August, Oslo remains one of the softer major-city markets.

That combination has pushed rental yields in the right direction. Global Property Guide's latest asking-price dataset puts the average gross yield in Oslo at roughly 4.5%, with one-bedroom apartments around 5.1%.

The problem is borrowing. Statistics Norway's latest available figures show new residential mortgages averaging 5.29%, slightly higher than the month before. A landlord borrowing at roughly 5.3% to buy an asset yielding 4.5% before expenses starts with very little room.

Current Oslo indicator	Approximate level	What we learn from it	Current direction
Average gross rental yield	4.5%	Decent by recent Oslo standards	Improving
1-bedroom gross yield	5.1%	Small units work much better	Relatively strong
3-bedroom gross yield	4.0%	Weak income for the capital required	Weak
New mortgage rate	5.29%	Still above average gross yield	Slightly worse lately
Oslo rents, year-on-year	+4.7%	Rental income keeps catching up	Strong
Oslo prices, first seven months of 2026	-0.8%	Purchase prices have stopped outrunning rents	Helpful

Are Oslo rental yields actually good today?

Oslo rental yields are reasonable for a wealthy European capital, but around 4% to 5% gross is still too low to call genuinely attractive.

The latest city-level estimates show a clear split by apartment size. A one-bedroom apartment costs roughly €396,000 and rents for around €1,685 a month, producing a 5.1% gross yield. Two-bedroom apartments sit just below 5%. Three-bedroom apartments fall to roughly 4%, even though the investor has to commit much more money.

Statistics Norway's rental survey explains part of that gap. In Oslo and Bærum, annual rent per square metre averages about NOK 5,270 for a one-room property, NOK 4,060 for two rooms, NOK 3,640 for three rooms and only NOK 2,740 for homes with five rooms or more.

Tenants simply pay much more rent per square metre for compact homes.

Adding an extra bedroom can therefore cost an investor heavily without producing an equivalent increase in rent. A small apartment can end up yielding more than one percentage point above a larger family property in the same city.

Oslo apartment	Approx. purchase price	Approx. monthly rent	Gross yield	Income appeal
1 bedroom	€396k	€1,685	5.1%	Good by Oslo standards
2 bedrooms	€528k	€2,185	5.0%	Reasonable
3 bedrooms	€788k	€2,595	4.0%	Weak
4+ bedrooms	€992k	€3,280	4.0%	Weak

Are Oslo rents rising fast enough to improve buy-to-let returns?

Yes. Oslo rent growth is currently strong enough to improve buy-to-let yields, especially because sale prices have recently moved much more slowly.

Eiendom Norge recorded a 3.6% jump in Oslo rents in the second quarter alone. Over the latest four quarters, rents rose 4.7%.

The longer trend is even more striking. Rental prices across Norway's largest cities have climbed about 32% since early 2022, compared with just over 20% inflation. The recent rise therefore goes beyond a simple inflation adjustment.

Meanwhile, Oslo house prices went in the opposite direction during much of 2026. They fell roughly 0.8% through July while national prices rose.

Imagine an apartment worth NOK 5 million generating NOK 210,000 of yearly rent. That is a 4.2% yield. If the property's value stays around NOK 5 million while rent climbs to NOK 225,000, the yield rises to 4.5%.

That is roughly what makes Oslo more interesting these days: rents are doing more of the work while purchase prices have stopped racing ahead.

Does a 5% Oslo rental yield really mean you earn 5%?

No. A 5% gross yield on an Oslo apartment will usually end up much closer to 3% once the property actually starts costing money.

Gross yield ignores common charges, insurance, maintenance, repairs, empty periods, letting expenses and larger periodic costs such as replacing appliances or renovating a bathroom.

Global Property Guide estimates that Norwegian net residential yields are commonly around 1.5 to 2 percentage points below gross yields. We would not apply that blindly to every apartment, but it gives a useful range.

A one-bedroom Oslo property yielding 5.1% gross could therefore leave something around 3.1% to 3.6% before financing and personal taxation. A larger apartment starting below 4% can quickly end up near 2%.

Take a NOK 4.3 million apartment producing around NOK 220,000 a year in rent. A realistic amount left after property-level costs might be closer to NOK 135,000–NOK 155,000.

The 5% number is useful when comparing listings. It tells us much less about what actually reaches the owner's bank account.

Can an Oslo buy-to-let make money with a mortgage now?

A heavily mortgaged Oslo buy-to-let will often produce little or negative cash flow at today's rates.

Statistics Norway currently puts new residential mortgage rates at 5.29%. That rate has actually moved up slightly lately rather than falling, from 5.23% the previous month.

Now compare that with a good one-bedroom apartment yielding roughly 5.1% gross.

On a NOK 4.3 million property financed at 70%, the mortgage would be around NOK 3.0 million. Interest at 5.29% costs roughly NOK 159,000 a year. Gross annual rent of about NOK 220,000 leaves only NOK 61,000 before common charges, maintenance, insurance, vacancy and tax.

At 90% leverage, annual interest would be roughly NOK 205,000. Almost the entire gross rent disappears before the owner has paid for anything else.

That is the catch with leveraged Oslo buy-to-let right now. Financing can eat most of the property's income before ordinary landlord expenses even enter the calculation.

Example: NOK 4.3m apartment	No mortgage	50% LTV	70% LTV	90% LTV
Annual gross rent	NOK 220k	NOK 220k	NOK 220k	NOK 220k
Mortgage	NOK 0	NOK 2.15m	NOK 3.01m	NOK 3.87m
Interest at 5.29%	NOK 0	NOK 114k	NOK 159k	NOK 205k
Rent left before other costs	NOK 220k	NOK 106k	NOK 61k	NOK 15k
Cash-flow position	Comfortable	Thin	Very thin	Poor

Does buying an Oslo rental with more cash make the numbers work?

Yes. An Oslo rental financed mostly with cash can produce a modest positive return today, while high leverage quickly ruins the economics.

Take the same small apartment yielding just above 5% gross. With no mortgage, the owner might keep a property-level return somewhere in the low-to-mid 3% range after normal expenses.

At 50% leverage, interest on roughly NOK 2.15 million costs about NOK 114,000 a year at current borrowing rates. If net operating income before financing lands around NOK 135,000–NOK 155,000, the investor may be left with only NOK 20,000–NOK 40,000 before personal tax.

That is positive cash flow, but it is a tiny immediate return on more than NOK 2 million of equity.

A low-leverage Oslo landlord is therefore relying on several sources of return together: rent, principal repayment and eventual price appreciation. The monthly rent alone will rarely make the investment exciting.

Would lower interest rates change Oslo buy-to-let quickly?

Yes. A meaningful fall in mortgage rates would improve Oslo buy-to-let economics much faster than another small increase in rents.

On a NOK 3 million mortgage, the current 5.29% rate means roughly NOK 159,000 of annual interest.

At 4%, that falls to NOK 120,000. The investor saves almost NOK 40,000 a year.

At 3%, interest falls to NOK 90,000, a saving of nearly NOK 70,000 compared with today's level.

Those amounts are huge when the underlying property's annual cash surplus may only be a few tens of thousands of kroner.

Building a purchase case around future cuts would still be risky. The latest official mortgage-rate reading actually increased, so cheaper financing remains potential upside rather than something landlords can count on today.

Mortgage rate	Interest on NOK 3m	Saving vs 5.29%	What it does to the deal
5.29%	NOK 159k	—	Difficult
4.5%	NOK 135k	NOK 24k	Better
4.0%	NOK 120k	NOK 39k	Much closer to workable
3.5%	NOK 105k	NOK 54k	Positive cash flow becomes easier
3.0%	NOK 90k	NOK 69k	Leverage becomes much more useful

Are small apartments the best Oslo buy-to-let properties?

Yes. Small Oslo apartments currently give landlords far more rent for each krone invested than larger homes.

The latest yield estimates put one-bedroom apartments around 5.1%, compared with roughly 4% for three-bedroom and larger properties.

Statistics Norway finds the same pattern from a completely different angle. Oslo and Bærum one-room homes generate around NOK 5,270 of annual rent per square metre. Five-room homes and larger average only NOK 2,740 per square metre.

That is almost a two-to-one difference.

Larger homes can attract families who stay longer, and lower tenant turnover has real value. But an investor starting more than one percentage point behind on gross yield needs those benefits to be substantial.

For someone buying primarily for rental income, compact one- and two-bedroom apartments deserve much more attention than big family units right now.

Are Oslo property prices cheap enough to make buy-to-let attractive now?

Oslo property prices have become more interesting, but they still look expensive relative to the rent they generate.

The important development is the gap opening between Oslo and the rest of Norway. Oslo prices fell around 0.8% over the first seven months of 2026, whereas national prices were up. Eiendom Norge later reported a strong 2.1% national rise in August, taking Norwegian prices up 4.9% for the year overall.

Oslo therefore entered the second half of the year from a much weaker position than most of the country.

That helps landlords because a softer purchase price combined with rising rents lifts the yield. But a decline of less than 1% does not suddenly turn Oslo housing into a bargain.

The city is still expensive enough that an average property bought at an average price generally produces an average yield around 4.5%.

The more convincing deals need something better than the city average: an unusually good purchase price, a high-rent small unit, low common charges or another clear reason why that particular apartment can outperform.

Can rising Oslo rents eventually turn today's mediocre yields into good ones?

Yes, if Oslo rents keep rising faster than property prices for several years.

Start with an apartment yielding 4.5%.

If rent rises 5% each year and the property price stays flat, the yield on the original purchase price reaches roughly 5.7% after five years.

If rents rise 4% annually and the property appreciates only 2%, the market yield gradually improves to roughly 4.9%.

But if both rents and property prices rise 5% a year, a new buyer still sees about the same 4.5% yield. The existing owner enjoys capital gains, but Oslo has not become a better income market.

This is why the recent rent-versus-price split deserves attention. Oslo rents have been rising while sale prices have been relatively weak. Another few years of that pattern would genuinely change the buy-to-let case.

Five-year scenario from 4.5%	Rent growth	Price growth	Approx. yield after 5 years	Effect
Strong rent catch-up	5%	0%	5.7%	Big improvement
Moderate catch-up	4%	2%	4.9%	Useful improvement
Rents and prices move together	5%	5%	4.5%	Little change
Prices outrun rents	3%	6%	3.9%	Worse for future buyers

How much do taxes eat into an Oslo landlord's profit?

Taxes reduce Oslo rental returns noticeably, although municipal property tax itself is usually a small issue for ordinary apartments.

According to the Norwegian Tax Administration, taxable rental profit is normally taxed at 22%. Legitimate rental expenses can generally be deducted, so the tax applies to profit rather than the full rent collected.

Wealth tax can matter more for a wealthy investor. A secondary home is currently valued at 100% of its calculated housing value for wealth-tax purposes, whereas primary residences receive a large valuation discount.

The exact effect depends on the owner's total assets, debt and tax position, so two landlords owning identical Oslo apartments may end up with very different after-tax returns.

Oslo's municipal property tax is lighter than many investors assume. The city currently applies a 1.7-per-thousand residential rate after a deduction of up to NOK 4.9 million. Because the taxable base for most homes is 70% of calculated market value, Oslo municipality says homes worth below roughly NOK 7.25 million will generally pay no property tax.

Even an NOK 11 million home in the municipality's own example produces annual property tax of only NOK 4,760.

For most small buy-to-let apartments, mortgage interest, income tax and common charges deserve far more attention than Oslo's municipal property-tax bill.

Do Oslo buying costs make short-term buy-to-let a bad idea?

Yes. Oslo buy-to-let works much better as a long holding than as a property you plan to sell again after two or three years.

Kartverket charges document duty equal to 2.5% of market value when qualifying freehold property changes ownership.

On a NOK 6 million apartment, that means NOK 150,000 immediately.

At NOK 8 million, it becomes NOK 200,000.

For an apartment collecting NOK 20,000 a month in rent, NOK 150,000 equals seven and a half months of gross rental income before the landlord has paid any running costs.

Borettslag cooperative apartments can avoid that specific document duty, which makes them interesting from an acquisition-cost perspective. But the apartment's share of cooperative debt and its monthly common charges need a close look. A unit advertised at NOK 4 million with NOK 1 million of associated common debt is economically very different from a debt-free NOK 4 million apartment.

Property value	2.5% document duty	Equivalent months of NOK 20k rent	Initial hurdle
NOK 4m	NOK 100k	5.0 months	Significant
NOK 5m	NOK 125k	6.3 months	Significant
NOK 6m	NOK 150k	7.5 months	High
NOK 8m	NOK 200k	10.0 months	Very high

Can Oslo landlords keep pushing rents up whenever the market rises?

No. Oslo landlords cannot simply copy the latest asking rent onto an existing tenancy whenever rents jump.

Norway's Tenancy Act allows rent to be adjusted in line with the consumer price index once at least one year has passed since the previous rent setting, subject to written notice.

A landlord can move toward the prevailing rent for comparable properties only after the tenancy has run for at least two years and six months under the relevant conditions. That adjustment also requires six months' written notice.

This creates a real gap between new asking rents and rents inside older contracts.

That gap is particularly relevant now because Oslo's market rents have been climbing quickly. A vacant apartment purchased today may capture the latest rent immediately. A unit containing a long-standing tenant may not.

So when assessing a tenanted Oslo apartment, the existing lease matters just as much as the rent shown on Finn.no for the apartment next door.

What can turn a seemingly profitable Oslo rental into a bad deal?

A thin starting yield, expensive debt and one or two unexpected costs can wipe out an Oslo landlord's profit surprisingly quickly.

Vacancy is one example. One empty month removes 8.3% of annual rent. A property starting at a 5% gross yield effectively falls toward 4.6% before any other cost.

Then consider a NOK 30,000 repair, a jump in common charges or a cooperative deciding to undertake expensive building work. None of those events is extraordinary in residential property.

A cash buyer with plenty of margin can absorb them.

A landlord whose mortgage interest already consumes most of the rent has far less room. On the 70%-leveraged example above, only around NOK 61,000 remained after interest before any other expense. One vacancy month and one moderate repair could use most of that amount.

This is why the building's finances, common debt, planned renovations and monthly charges deserve almost as much attention as the purchase price. A cheap-looking apartment can become expensive very quickly.

Is Oslo better for buy-to-let than Bergen or Trondheim today?

No. Oslo currently loses to both Bergen and Trondheim if we compare straightforward rental yield.

Global Property Guide's latest city comparison puts Oslo's average gross yield around 4.5%, versus 5.1% in Bergen and 5.3% in Trondheim.

For small apartments, Bergen looks even stronger. Its estimated one-bedroom yield reaches roughly 6.2%, compared with around 5.1% in Oslo.

One percentage point sounds small until we apply it to real money. On NOK 5 million of property, an extra percentage point represents NOK 50,000 of annual gross rent.

Oslo still offers obvious advantages: Norway's largest employment market, a deep tenant pool and a liquid housing market. Those qualities are expensive, though. Investors are accepting a lower current yield to own property in the capital.

If the main goal is income today, Bergen or Trondheim currently has the stronger numbers.

City	Average gross yield	Strong small-unit yield	Income ranking
Oslo	4.5%	about 5.1%	Third
Bergen	5.1%	about 6.2%	Second
Trondheim	5.3%	about 5.6%	First

Is capital appreciation still the main reason to buy an Oslo rental?

Yes. For many buyers, the Oslo buy-to-let case currently depends more on long-term total return than on impressive monthly cash flow.

A cash buyer earning perhaps 3% or slightly more after normal property expenses can still do well if Oslo property values appreciate over a long period.

Suppose the property produces a 3.2% net operating return and appreciates 3% annually. The combined pre-tax economic return is roughly 6.2% before transaction costs.

Leverage can increase the return on the investor's equity when prices rise, but it also makes today's weak cash flow worse and magnifies losses if prices fall.

Recent Oslo performance is a useful warning against assuming appreciation is automatic. The capital has lately lagged markets such as Bergen, Stavanger and several smaller Norwegian regions by a wide margin.

Future appreciation belongs in the upside case. It should not be used to rescue a rental property that already loses money on its basic operating numbers.

What would make an Oslo buy-to-let genuinely attractive right now?

We would start getting interested around a 5.5%–6% gross yield, particularly on a small apartment with moderate debt and clean building finances.

At 6% gross, there is much more room for normal costs while still retaining perhaps 4% or a little more at property level.

That does not suddenly make 90% leverage sensible while new mortgages cost around 5.3%, but it gives an investor far more breathing room than the Oslo average of 4.5%.

The best-looking setup today would probably involve a compact one- or two-bedroom apartment, strong achievable rent per square metre, modest common charges, limited cooperative debt, no major renovation looming and a purchase price below comparable nearby transactions.

A large apartment yielding below 4% is much harder to defend, particularly if the deal also carries expensive common charges and a large mortgage.

Oslo is currently a market where buying the right apartment matters far more than simply deciding that “Oslo property” is a good investment.

So, is buy-to-let property profitable in Oslo now?

Yes for selected low-leverage properties, but the average mortgaged Oslo buy-to-let still produces too little cash flow to call the market broadly attractive today.

The numbers now point in a fairly clear direction. Oslo rents keep rising: Eiendom Norge recorded 3.6% growth in the latest quarter and 4.7% over the previous four quarters. Sale prices, meanwhile, have been much softer than in most of Norway.

That has pushed small-apartment gross yields above 5% in some cases.

Once normal property expenses are deducted, however, the return can fall into roughly the 3% range. Current new mortgage rates around 5.29% then leave highly leveraged landlords with very little cash left.

The buyers who can make Oslo work today are fairly easy to identify. A cash buyer can earn a modest positive income and keep the long-term appreciation upside. Someone using around 40%–50% debt can make a particularly good small apartment work. At 70%–90% leverage, the deal becomes much harder unless the purchase yield is well above the city average.

The direction is encouraging. Rents are still climbing, weaker Oslo sale prices are helping yields recover, and any future drop in mortgage rates would improve the equation quickly.

But based on what landlords can actually buy, rent and finance now, Oslo remains a selective buy-to-let market rather than an easy one. A well-bought small apartment with conservative financing can be profitable. An average apartment bought with a large mortgage usually cannot.
