Unless you have an unusual tax situation, it probably won't matter.
The 25% federal tax bracket goes from $75,300 to $151,900 of taxable income (which is your gross income minus adjustments, deductions, and exemptions). You'll probably be in this bracket this year and next year. In this bracket you'll pay 15% of the gain.
If you live in MN, they have a 7.05% rate from $36,650 to $145,620 of taxable income. Above that upper number, it goes up a little bit to 7.85%.
Instead of selling it this year or next year, you could just hang on to it and not pay capital gains taxes at all (at least until you sell it later).
