Temporary renting out house

Hi everyone, long story short, we will stay abroad for approx. 1 year, but don't want to sell our house. Renting it out for a short period is almost impossible today. Only exceptional cases seem to be allowed by the banks where you need to let your employer sign a document that the start+end date is stated and your job is there for you when you return (Diplomat Clause). Unfortunately we don't have that option.

Leaving it empty feels sad with the current house situation.

Just wondering, what are other options? Can I let family/friends live in it for free and only let them pay the utilities?
