All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

The question is somewhat ambiguous, and we could not fully understand all the details. However, we can generally underline some important points related to the division of inheritance.

First: the sisters have the right to act freely with regard to their rightful shares of inheritance by sale or otherwise, and the fact that the property has been in your family for many generations and that selling it would allow the legacy of the family to be lost and other similar excuses do not prevent them from free disposal of their shares in it. However, you or another person may reach an agreement with them to buy their shares, if you can, in order to keep the property as you wish.

Second: if the estate has been divided (among the heirs) and your share in it is defined, you may dispose of it as you wish, by building on it, renting it, cultivating it, or by utilizing it in in any other permissible manner.

Third: the issues of inheritance and cases of dispute should be referred to the scholars directly so that they would inquire about the needed details without having to make assumptions that may not exist in reality.

Allah Knows best.
