Look at it this way. If you want to full time for several years, what are you going to do with all of your stuff? You really only have three options:
1. Retain the house with all of the stuff in it and continue to pay insurance & taxes on the house and hope nothing happens to it.
2. Put the majority of it in storage and pay $200+ a month for storage fees for ever.
3. Sell it for what you can get for it which will probably be pretty low. You might put certain expensive items like tools and china in a small storage place that doesn't cost much.
