Here are some tips if you are downsizing!
Take photos of your home before you downsize. Not only can it be fun to look back at your old place after you move it can also be a tool to help you select what to take with you.
Keep things you want, use, need, or like to look at. You want to identify the things that make your house a home.
Finally, don’t over-save for the next generation because chances are they would rather collect experiences than stuff.
