Can I comment on the storage unit subject?
I think the main consideration when trying to decide what to get rid of and what to pay to store is to determine how much you will pay over time for the storage vs the value of what you are storing. If you are storing sentimental items only most likely when you come back to the storage unit you will wonder why you paid to store things you should have gotten rid of to begin with.
Furniture doesn't cost all that much to replace and you would be starting over. The cost of storage could be banked for new furniture and "stuff". JMHO.
