• Sale and Purchase of House Property

My queries are as follows:
Mr. V owns one residential house in Puducherry. He is also co-owner in two residential houses in Maharashtra, and co-owner in two residential houses in Karnataka. The co-owners are: 1. Wife in case of one house property in Maharashtra;2. Mother and sister in case of one house property in Maharashtra and two house properties in Karnataka.
Query 1
If Mr. V sells the residential house, of which he is the sole owner, in Puducherry and invests the proceeds in a new residential house in Karnataka within the period stipulated in Section 54 of the I.T. Act, can he claim exemption from capital gains tax?
Query 2
In addition to the above, if the Mr. V and the co-owners of the other properties in Karnataka and Maharashtra sell the house properties, and Mr. V invests his share of the sale proceeds of the houses, together with the sale proceeds of the house property in Puducherry owned solely by him, and invests the total proceeds in one residential house in Karnataka, can he claim exemption from capital gains tax under section 54 and/or Section 54F of the I.T. Act?
Query 3
If one or more of the co-owners of the residential houses in Maharashtra/Karnataka join Mr. V in investing their share of the sale proceeds of the co-owned houses in one residential house in Karnataka, will the co-owners, together with Mr. V, be exempt from capital gains tax under Section 54 and/or section 54F of the I. T. Act?
In this connection, reference may be made to the I.T.A.T ruling reported at page 1 (continued on page 5) of the Sunday Times of India, Bengaluru edition, dated June 11, 2023.
