I don't think this is much of a big deal.
1) If you live there for 2 years, then the first $250,000 in profit is tax free. You can just wait it out a bit. Heck, with the current housing market, it'll probably will take you to the 2 year mark just to sell it. You'll have to check up on this, but I think the tax is prorated for the amount of time you are there IF you change jobs which you did. Thus, you don't even have to spend the full 2 years there.
2) Even if you did pay taxes, the tax rate is small. At worst it would be 15% tax rate of $15k; that comes out to $15k * 15% = $2250. If you are in the lowest 2 tax brackets, the capital gains are 5%, for a tax of $15k * 5% = $750. That is not THAT much tax.
3) Remember home improvement costs are subtracted from the profit. So if you have receipts for those repairs that you mentioned above, then you probably can drop that $15k significantly. If you spent more than $15k to repair the house or other related costs, you wouldn't owe a single penny in tax.
4) Other expenses are also subtracted. For example, the ~6% realtor fee is subtracted. This reduces your $15k "profit" even further.
