如果你应交$10K，减去$8K，还剩$2K，很合算

But the requirement is quite high. Neither of the spouse could have owned a house in the past 3 year. You have to live in the house for 3 years. Also, the closing has to be one or before 11/30, tight schedule. If you wanted to buy a house, go ahead. If not, then you need to think twice about why you want to buy a house. $8000 should not be the only reason. It should be icing on the cake, so-to-speak.
