Why this matters now
The mortgage-rule change from 1 April was easy to summarize and harder to feel. A cap moving from 85 to 90 percent sounds like five percentage points. For a first-time buyer, it is really a savings-calendar story: less money has to sit in the account before a bank can even consider the purchase.
SBAB tested that against the average price of a 35-square-metre one-room flat in the 25 largest municipalities, using median income for 25- to 29-year-olds. The result is more hopeful than the old first-home story. Men with median income pass the test in 23 municipalities when they have 15 percent cash. Women pass it in 19.
The cash gap is the readable number
SBAB's easiest example is a SEK 2 million home. At the old 85 percent loan-to-value ceiling, the buyer needed SEK 300,000 in cash. At 90 percent, the same price needs SEK 200,000. The apartment is no cheaper, and the loan is larger, yet the first hurdle is SEK 100,000 lower.
The municipal spread is wider. SBAB says a 15 percent deposit for a typical one-room flat ranges from SEK 85,000 in Sundsvall to just over SEK 500,000 in Stockholm. With 10 percent cash, the same comparison becomes SEK 57,000 in Sundsvall and SEK 333,000 in Stockholm, assuming unchanged prices.
Stockholm still breaks the pattern
The sharper part of the release is that Stockholm stays outside the new comfort zone. SBAB says 27-year-olds with median income cannot buy the average one-room flat in Stockholm, whether the deposit is 10 or 15 percent. Lund also fails the 15 percent test for men, while Stockholm remains the main outlier under both deposit assumptions.
That is useful because it separates two different problems. A lower deposit helps people who were close on cash. It does less for a buyer whose income cannot support the monthly loan calculation. SBAB used a 6.25 percent calculation rate in the test, and the bank still has to assess the borrower's repayment capacity.
The rule change is real, and the bank test stays
Finansinspektionen says the new law applies from 1 April 2026 and raises the mortgage cap for a new home purchase from 85 to 90 percent of market value. FI also says the stricter amortisation rule for loans above 4.5 times annual income has been removed, while the ordinary amortisation steps above 50 and 70 percent loan-to-value remain.
Regeringen frames the same change as a way to make home ownership easier for young buyers and growing families. That does not turn the 90 percent ceiling into a promise from any bank. It makes a higher loan-to-value possible; the income, fee, interest-rate buffer, other loans, and the home's price still decide the final answer.
The price effect is still open
One fear around easier mortgage rules is that lower cash hurdles simply push prices up. SBAB says its Booli price index has not shown a large spring price lift from the new rules so far. Apartment prices were flat in May after a weak rise in April, according to the release.
That makes the current moment more interesting. The policy has lowered the cash wall for some buyers before the data shows a clear price jump. If prices move later, the deposit math can change again. For now, the map says the door opened in many large municipalities, while Stockholm is still its own game.
What to watch next
The next useful signals are local apartment prices, average monthly fees, bank calculation rates, and whether more first-time buyers actually sign contracts after the rule change. A lower deposit can shorten the savings phase, while a higher loan can raise interest costs. Both facts belong in the same picture.
The clean read from SBAB's map is this: the new cap matters most where the buyer was cash-constrained rather than income-constrained. In Stockholm, income and price still do most of the talking.
