Price is from 50 to 100 for b&b here in CH, if we take the lower average, chf 70, multiply that with 300 (based on 80% occupancy) then we have chf 21.000.- income a year for one room.

If you have a few rooms, then this sounds like a good deal to me?

Not that I have any experience in such matters, but I would say that you are probably bordering wildly optimistic with your occupancy assumption. If it is travel then surely it will be cyclical with higher levels on or around weekends and lower mid-week, all within seasonal fluctuations too.

Also crucially you have not stuck in any form of cost assumption in there. With B&B there is a reasonable chunk going to be taken out via breakfast.

Bung in a healthy chunk on taxation and I can see your margins being seriously depleted for what is a lot of work.

I haven't any experience of the working side of it but these days B & B in England at any rate often means a largish bedroom with en suite bathroom, pleasant breakfast room a access to another room in the evening.

The 'owner' must be around during the evening and must be available until the last 'sleep-in' types have eaten their breakfast, packed and got out of the house the next morning. And then the cleaning, washing, ironing starts.

As cmjohno says, you will almost certainly have times of year or days of the week when you have no-one coming and other days when you are turning folk down by the dozen.

It seemed like a good idea at the time...
