Housing mortgage for foreigners in Norway

Welcome to Norway.

I went to the bank and inquired this, if you have work permit and a proper salary, you can get loan and buy some real estate.

Basically, u can get loan up to 3 times your yearly salary, but it's also case by case.

Good luck!

I can confirm JamineJasmine's post.
I recently came from the states and went to a bank and showed them my paycheck stubs with my employer contract and based on my salary they gave me a loan and we're currently looking for a house now.
3 times your salary is about right.
It may be adjusted if you're married and have kids or any other type of loans, such as car loans here in Norway. 
the process was very easy.
You will need a person number, your work visa/permit/ passport, bank account, paycheck stubs, and work contract.
Also, when you get your tax card, make sure that you fall under Tax table 7300 which is typically for foreigners.  This will allow you the standard deduction of up to 40K kroners and you'll get more in your pocket every paycheck.  You can only do this for the first two years.
Should you get a loan on a house and you'll want to write off the interest, you cannot take advantage of the foreign taxworker standard deduction.

Hi
I have known that the DNB gave you 75% of house price, but here the house are too expensive (3 to 4 million), do you think as a newcomer government will help you to buy house by lending you more loan?

Thanks

For Abder84: yes you will be able to buy as the other posters have confirmed. These days however, you may need to give more than 10% as your cash contribution to the purchase. The real estate market is considered being in a bubble by some here and the banks become more careful. It could be they ask you to provide in cash up to 25% of the sum.

For Mitramor: there is very little state support in that area and nothing for newcomer. Kommune (communities) may provide a loan for your first apartment purchase but the process is rather cumbersome and long.
