If I take $10K out of IRA for first time home purchase, use it and then come up with extra $10K within the next 4 months, can I put that $10K back into the IRA within the 120 day period (i.e,. basically get a 120 day interest free loan)?
On one hand, I would think no because the spirit of the law suggests that's not something that you are supposed to be able to do with an IRA.
On the other hand, one does have 120 days to put the $ back into the account should the house purchase fall through, and given that money is generally fungible, one could argue that one is indeed putting the same money back into the IRA.
