I'm so glad your DH got a job! Yay!
I would NOT sell the house. My guess is that you could not even rent a place for under $600 a month, and if it's anywhere like where I live, the place would be a utility-sucking hellhole anyway. Not to mention paying deposits for turning on utilities (which are higher for renters than homeowners) I really REALLY don't think it's a good idea. I'd do anything and everything to get those back taxes paid off ASAP though. It would be terrible to lose your home for a lack of a few thousand dollars.
I still thinking renting a room is a good way to go. Do you have a college in your area? I'd try to rent to a young single girl if I was in your position.
Definitely cut cable. I haven't had cable in three years and I don't miss it a bit. I have Netflix and I watch all the TV I want for $8 a month. You might also research Roku, which is about $50 for initial setup for the cheap version, and you can watch Netflix (per month charge) plus I think they have a huge selection of streaming on it's own. In this day and age, I would NOT pay for cable/satellite.
Close off every room in your house that you can. Cover the windows with blankets/towels to try to make them more efficient. If you MUST run A/C, don't run it so cold.
For winter, could you get a cheap woodstove and burn wood to heat the house? In my area, I see stoves being given away all the time on Craigslist. The expensive part is usually the piping, but it would probably pay for itself in a matter of one winter. The wood on your property might not be good to sell as firewood, but it might be sufficient to heat your own home with.
If you have that much land, I'd definitely grow some food/raise some chickens. And even if you don't grow food, you can buy it when it's cheap in the summer and can/freeze it for winter. Last year I made enough jelly to last us the entire year with four quarts of strawberries and a bag or two of sugar. We use a LOT of jelly for PB&J sandwiches.
Good luck to you!!!!
