Oh, yes... (thanks Perna for reminding me..) if you can wait to move, even downsize and buy... do so. There is new legislation regarding tax percentages for homeowners. If you move and buy now you will be under the higher tax but soon you might be able to buy something smaller and still keep the low tax level you currently have (from when you bought this home.)
Be sure to check where you're moving that they allow all your animals though. (Some towns have limits... or even a community might.)
Why not check and see how much equity you have in your home? Any realtor will pull "comps" for you... homes in the area that have sold and are similar to yours... they can tell you what they sold for and you can compare what you owe with what you might be able to sell for... or get a new mortgage for, taking some equity out for upkeep? I think you know much of this... sorry if I'm not encouraging you to move. Owning is important. I just want you to find that.
