Not sure for all countries but you will have to consider-
Surely if you intend to work in any country then you are going to need the following
1. A registered local home address(in the visiting country) To enable you to get a job and pay all local taxes
2. A job which you cannot get without a local home address
3. Some countries will require that you get a local work permit which you cannot get without Items 1 and 2 so catch 22 situation
4. You will have to make sure all your local taxes are fully paid before leaving that country.
5. You cannot get a local bank account without item 1 and no credit cards without item 2.
6: You will also have to pay local health insurance or arrange for private insurance in the UK

I live in CZ and some of my friends have been out of work for 12 months here as local companies find it cheaper and less hassle to employ locals who have all the language skills anyway, including TFL. So you might find it takes longer to get a job.
Renting accommodation can be a pain as sometimes the landlord will want references and deposits so be warned
Even though you are visiting EU countries there are still restrictions on how long you can stay and if you can work.

I would strongly recommend that you do your research into the countries you want to stay in to fully understand the restrictions and costs involved there are always some hidden details that will catch you out. Its one thing just to visit but totally different when living somewhere.

PS. If you sell your house then you will have to tell your bank, change your passport with new UK address, Change your driving licence address, change the bike insurance for extended stay outside of the UK, arrange health and life insurance.

Good luck:confused1:
