It all depends on your situation. Will you be working on Boise or Eagle? What are your activities? Boise and Eagle are both good places to live. Give me a little mor information and I will give you a better answer.
2nd If you want the tax credit you should be looking to buy right now, especially if you are going to try and get in on a Short Sale. I have short sales that have been pending for 5 months waiting on bank aproval to sell the home at the price offered by my buyers.
3rd I don't think anyone can read the crystal ball well enough to say that now is the bottom of the market. You will not know the bottom until you have missed it. Signs are improving now, which may indicate we have hit the bottom of the market, but no one can be sure.
4th, Boise or Eagle are both great. It depends on your needs. No way to answer that with the limited information you provided. But if you need to get specifi advice anytime, fill free to give me a call 830-7991 and I would love to help. It will not cost you anything and I promise not to try and sell you something. I just love real estate and like helping people.
