Since you mention the rental ... have you been reporting that income on your taxes and taking depreciation on that portion of the property? That makes your taxes on the sale a bit more complicated.
I agree that you should sell. The tax hit is still going to be less than your the savings on expenses, but it's not quite as straightforward as pb4uski's estimate when you factor in that rental usage. If you're not comfortable with the section of IRS pub 523 that talks about gain/loss calcs when having a separate rental unit on the property, then you should plan to have a pro do your taxes for the year that you sell.
Fair point... I guess I read past the rental in the walk-out basement. Of course it depends on whether the OP has been using Schedule E or just his pocket.
