Once her life estate is terminated, she is entitled to nothing. A life estate means she has a aright to use the property while she is alive but can not sell it, encumber it, nor damage it. There must have been some document, probably a Trust, that established the life estate and that document has to be followed as to ending it. I do not believe you would have to pay any capital gains tax on the transfer to you and your brothers as you technically the owners of the property. If you are all owners, then you have the right to do with the property as you want and if the brothers want to sell it they would have to file an action for partition of the property, which could easily cost $15,000 or more if it is fought by you.
