My mother passed away, leaving her estate (including her house) to me and my three brothers (I am the executor). She had no debt. Can one of my three brothers buy the house from the estate and get the first time home buyer tax credit? He meets all of the other criteria.

No. This is inherited property. Your U.S. Tax Return: First-Time Homebuyer Credit

I saw that there was an inherited property restriction, but my mother did not leave him the house; he is a co-beneficiary with me and my other two brothers. He would have to buy the house from the estate, so does the inheritance restriction still apply? The purchase price is $300,000.
Thanks.

Just a follow up to my original question. I checked with an attorney (who handles real estate closings) and two tax professionals, and they all agree that since my brother would be buying the house from the estate, he is entitled to the tax credit. Does anyone have a different opinion?
Thanks.
