Mrth, it sounds wonderful. Holding out for the " Perfect " spot could take years, better to get moving a head with what you have. I am pleased for you. Lowering your carbon foot print is always a good thing for the planet.
Down sizing is never easy. I am a Hoarder and Love my stuff. It makes me feel good to look at it. But do I NEED it, no, does it complete me, no, it is a hard bullet to bite, but you can do it. Much of the stuff in my basement has been there for low these many years not. I still have books from college that I have never looked at in 30 years, there is stuff from High School for goodness sakes, I keep them to trigger memories I guess. You will find that once you get started down sizing it will be easier than you think. It is amazing how little we actually Need to get by. Good Luck.
