Has anyone here done this? We have wa Ted to buy for years but stuck in a rut of renting and can only save a minimal amount. I have seen some from Germany for Amazing price and obviously I haven't done much research as it was a fleeting thought that we have seen advertised before. Is it worth it? I read if taken care of properly they can last for decades. Not sure if that'd true. Or is it too much of a head ache regarding gas and electric and water connections. Planning and regulations?
