There's so much missing from you r post that it's hard to answer meaningfully.
For example, you've not told us whether your father has written a will and, if so, who benefits from it. If your father hasn't written a will then (unless there are relevant factors which we're unaware of) you and your brother will each inherit half of his estate, so you'd either have to sell it or, if you wanted to move there, to buy your brother's share from him.
Further, we don't know whether one house has a better location than the other (in regard to proximity to your work or to pubs, shops, etc). Neither do we know the relative sizes of the properties. (if you're on your own you might choose to live in a small property, to cut down on cleaning and on heating costs. Alternatively you might prefer to live in a larger property to enjoy the benefits of the extra space).
