Can I keep my Norwegian house and still emigrate for tax purposes?

Usually not — a home at your disposal in Norway is the single strongest factor keeping you fully tax liable under the 3-year rule. Renting it out on a long, arms-length lease changes the analysis; keeping it 'available for summers' does not. The risk is silent: nothing happens until Skatteetaten reviews years later. Decide the house question before the move, not after.
