There is a tradition according to which in each of his next incarnations Sai does not return to his previous ashram, but establishes a new one. For example, Sathya Sai Baba did not live in the ashram in the city of Shirdi, which he founded in his previous incarnation as Shirdi (1838 - 1918).
It can be assumed that Prema Sai will follow this tradition and choose to establish a new ashram. This is mainly due to the fact that not all followers of Sathya Sai Baba are ready to take his new form as Prema Sai.
