BRF finances: how to read the annual report before you buy

Seven mandatory key figures since 2023, rule-of-thumb levels for debt and savings per sqm, and what interest sensitivity means. How to judge a BRF.

Updated: 2026-06-02

You are worried about buying into a BRF (bostadsrättsförening, a housing cooperative) with weak finances, and about the monthly fee jumping after you move in. The good news: since the 2023 financial year every housing cooperative must report seven key figures in its annual report, precisely so that you as a buyer can see the borrowing, the savings and the future plans before you put in a bid. With those numbers and a few rules of thumb, it takes ten minutes to form a rough view.

The seven mandatory key figures

The requirement applies to the first financial year that begins after 31 December 2022, in other words from the annual report for 2023. Five of the figures follow from the Annual Accounts Act and two are added under the Swedish Accounting Standards Board’s general rules. On top of that, the annual report must contain a cash-flow statement, and if the cooperative reports a loss, it has to show how future commitments will be financed.

Key figureWhat it tells you
Annual fee/sqmHow much you pay per square metre per year
Debt/sqm (total area)The cooperative’s loans spread across all floor area
Debt/sqm (housing-cooperative area)Loans spread across the flats, often the most telling
Savings/sqmHow much the cooperative sets aside for future maintenance
Interest sensitivityHow much the fee may need to rise if rates go up
Energy cost/sqmWhether the building uses a lot of electricity and heat
Annual fees as % of operating incomeHow dependent the cooperative is on your fees

Debt: the number you look at first

There is no legal limit on how much a cooperative may borrow, but banks and managers tend to use roughly the same rule of thumb. Under about 5,000 kr/sqm is good, and over 10,000 kr/sqm is a signal to look into why the loans are so large. Different players set the “good” threshold somewhere between 5,000 and 6,000 kr/sqm, but above 10,000 kr/sqm everyone agrees it is worth a closer look.

High debt on its own is not a disaster, but it makes the cooperative vulnerable to rate rises. That is where the interest-sensitivity figure comes in: it shows roughly how much the annual fees would in theory need to rise if the cooperative’s loan interest rate went up by one percentage point. The lower the number, the less you as a resident are affected. A cooperative with little debt and high savings can absorb a rate rise without touching the fee. A heavily borrowed one may be forced to raise it.

Savings: money set aside for maintenance

A building needs ongoing maintenance, and the money has to come from somewhere. As a rule of thumb, healthy savings sit around 200-300 kr/sqm, where above about 250 kr/sqm is usually seen as strong and below about 130 kr/sqm as weak. Low savings combined with high debt and an old building is the mix you want to look at most carefully, because then a fee increase or an extra loan may be closer in time.

Worked example: two cooperatives, same fee

Say you are comparing two flats of 70 sqm, both with a monthly fee of 4,000 kr.

Cooperative ACooperative B
Debt/sqm4,200 kr11,500 kr
Savings/sqm280 kr110 kr
Interest sensitivityLowHigh

The fee is the same today, but the cooperatives are not equally safe. Cooperative A has low debt, saves well and can take a rate rise without touching the fee. Cooperative B has high debt and saves little, so a rate rise or an upcoming stambyte could force a fee increase. Same monthly cost in the listing, very different risk behind it.

Stambyte: the big cost still to come

Pipes (the water and drainage lines) normally last 40-60 years, so a stambyte (replacement of those pipes) comes round about once a generation of residents. The cost is roughly 200,000-400,000 kr per flat, because bathrooms are often torn out and rebuilt. These are guide figures from managers and contractors, not an official statistic, but it is why the building’s age matters. If the building is 45-55 years old and the stambyte has not been done, ask the agent and check the maintenance plan. If it has just been done, you have a big item out of the way.

Do I need to fear bankruptcy?

No, it is very rare for an active cooperative to go bankrupt. The number of BRF bankruptcies has risen (about 117 concluded during 2024), but that should be set against the roughly 30,000 housing cooperatives in Sweden. Much of the increase also came from dormant cooperatives with no activity being deregistered, not from operating cooperatives with residents. The bostadsrätt (housing-cooperative tenure) is a large form of ownership in apartment blocks: at the end of 2024, 42 percent of flats in apartment blocks were owned by housing cooperatives. Put your energy into debt, savings and maintenance instead, because that is where the real difference between two cooperatives lies.

New mortgage rules from 1 April 2026

From 1 April 2026 the mortgage cap rises from 85 to 90 percent of the property’s market value, so the minimum down payment falls to 10 percent. At the same time the stricter amortisation requirement is removed (the extra 1 percent that applied to households with mortgages above 4.5 times gross annual income), while the basic amortisation requirement stays: 1 percent at a loan-to-value of 50-70 percent and 2 percent above 70 percent. As a counterweight, top-up loans are limited to no more than 80 percent of the property’s value, and a home may not be revalued for extra borrowing room more often than every five years.

Common questions

Which key figures must appear in a BRF annual report?

Since the 2023 financial year, seven key figures are mandatory: annual fee per sqm, debt per sqm (total area), debt per sqm (housing-cooperative area), savings per sqm, interest sensitivity, energy cost per sqm, and annual fees as a percentage of operating income. Five follow from the Annual Accounts Act and two from the Swedish Accounting Standards Board. A cash-flow statement is also required.

How much debt per sqm is acceptable in a housing cooperative?

There is no legal limit, but a common rule of thumb among banks and managers is that under about 5,000 kr/sqm is good and over 10,000 kr/sqm is a sign you should look into why the borrowing is so high. Different players set the "good" threshold somewhere between 5,000 and 6,000 kr/sqm. Reporting the figure is mandatory, but how to interpret it is not regulated.

What does interest sensitivity mean in a BRF annual report?

Interest sensitivity is one of the mandatory key figures. It shows roughly how much the annual fees would need to rise if the cooperative's loan interest rate went up by one percentage point. The lower the number, the less you as a resident are affected by rate rises. High debt usually means high interest sensitivity.

What does a pipe replacement (stambyte) cost per flat, and how often is it done?

Pipes normally last 40-60 years, so a stambyte (replacement of water and drainage pipes) comes round about once a generation of residents. The cost is roughly 200,000-400,000 kr per flat, because bathrooms are often torn out and rebuilt. These are guide figures from managers and contractors, not an official statistic, and the cost varies with the building's age and condition.

How common is it for a housing cooperative to go bankrupt?

It is very rare for an active cooperative to go bankrupt. The number of bankruptcies rose in recent years (about 117 concluded during 2024), but that should be set against the roughly 30,000 housing cooperatives in Sweden, and much of the increase came from dormant cooperatives with no activity being deregistered, not operating cooperatives with residents.

What changes in the mortgage rules in 2026?

From 1 April 2026 the mortgage cap rises from 85 to 90 percent of the property's value, so the minimum down payment becomes 10 percent instead of 15 percent. At the same time the stricter amortisation requirement is removed (an extra 1 percent for households with mortgages above 4.5 times gross annual income), while the basic amortisation requirement stays. Top-up loans are limited to 80 percent of the value.
