Consider these options:
1. Start decluttering right away because seven years will go quick. I found the more I decluttered, the more decluttering, I needed to do. Especially paperwork and clothing.
2. If you haven't touched it, in a year, you won't miss it or need it.
3. The older you get, it's harder to clean-up, when you have too much stuff. You would wind-up decluttering at some point, when you are in TV, so do it now.
4. I used to be a pack rat, and had tons of stuff I never looked at, but kept, in case I needed it. I never needed it.
5. The real estate sale idea is excellent, to get rid of stuff.
6. In today's world, you never get full value for used stuff, unless it's something like art or antiques.

I found moving from one state to another, is much more difficult, as you have to decide what to keep, and what to throw away. It's also better to buy new furniture to fit the FL lifestyle, as it will cost more, to bring all your stuff down. IMHO

Going through all your stuff will be very time consuming, so it's smart to start now, and be able to do it, a little at a time.

I hope this helps you.
