Okay, I see. Three more small questions to finish:
1. Will it work for my spouse who is a homemaker and is able and wants to spend at least 190 days in the new home? I asked this question, but I am not sure you really amswered it.
2. It is not about the logic, I dare think. It is about the law in my understanding: the law (regarding the tax credit) says that the only important factor is time (there are no any words about ID, banks, employment, etc.). By the way, frankly speaking, I do not understand why you use "relevant factors in deciding whether a property is principal residence". These relevant factors were created long before the tax credit under discussion was suggested and they were used for other purposes: I failed to find IRS documents discussing the relevant factors with respect to the tax credit for first time home buyers. Is it simply an established practice based on some
Anyway, I can submit calculations showing that I can spent more time in the new house than in the rented house if I am examined. Why will it be ignored in your opinion?
3. "It would be difficult for you to argue it otherwise should you be examined." If I fail to convince the examiner, what will be the penalties? They will ask to return $4000 or $8000?
