AA Magazine had a feature on their FFer of the year a couple of years ago. She was doing the same sort of thing. I think the hotel didn't even bother to charge her for the weekends or something like that. Not for me, but good luck.
One other suggestion, I notice your name is BostonJim. Not sure if this means your old home was near Boston, but if it is you should talk with a tax expert. MA is odd in that they still require you to pay state taxes if you haven't established residency in a new state. I don't remember the details, exactly, but it came up when I took my expat assignment and I was told that I will still have to pay MA taxes, even though I will live and work in Europe for the next three years. If you can make a reasonable case for residency in NH or TX or another tax-free state, for example, you could save a bundle.
FYI - I use HomeNet International out of Belmont, MA for mail forwarding. They are pretty good if you haven't found another service.
