The power of attorney which your father delivered to your brother died when your father died. The distribution of the estate is determined by the terms of the will. If there are two different wills, the terms of the latest will prevail unless there is evidence that the will is invalid due to the existing of circumstances such as lack of mental capacity, fraud or undue influence.
Based on your comments, it seems that your brother is the classic freeloader who has no intention of leaving the property voluntarily. I would recommend that you hire counsel to enforce your rights under your father's estate plan. Good luck.
This response does not constitute the establishment of an attorney-client relationship. It is also not to be taken as firm legal advice as such would be contingent on a full inquiry by the attorney into the complete background of the facts and circumstances surrounding this matter. The response is meant to be a helpful guide to a question in a manner which reflects the limited information provided by the inquirer.
My deepest condolences for your loss. Ultimately, you will need to determine which will is valid. A well-drafted will usually contains a provision that revokes all previous wills, meaning that the will with the most recent date is probably the valid one. If, however, the more recent will does not contain such a clause, parts of both may still be valid. You will probably have to have an estate attorney in your area examine both wills to determine their status. Note that now that your father has passed away, your brother's power of attorney no longer has any legal effect. The power to administer the estate rests with whoever is the executor of the valid will. Once you determine which will is valid you will have to offer it for probate before you can start disposing of the property in the estate. A probate lawyer in your area can help you with that as well.

My condolences on your loss.
The Power of Attorney is no longer valid - it ceases at someone's death.
The Executor of the Will then has the power (and duty) to settle the affairs if your Dad.
As previously stated (and from what I Infer), it appears that there is friction.
Although I rarely encourage the hiring of an attorney (it is self-serving) nor ever disparage someone's family member (after all - he is still your brother), I would suggest that your brother and you quickly attempt to put out this fire before it becomes something that both of you may regret.
Good luck - at least, to me, nothing is ever worth breaking up a family. I am sorry you are experiencing this.
