(6)Condition E is that if each dwelling-house were disposed of immediately after the disposal (or disposals) mentioned in subsection (5) then by virtue of sections 222 and 223 (private residences) no part of the gain accruing on each of those disposals would be a chargeable gain.
(7)The landowner, on making a claim jointly with the co-owner or co-owners, shall be treated for the purposes of this Act—

(i)at the time it was acquired jointly by the landowner and the co-owner or co-owners, and
(ii)for a consideration equal to the amount of the sums that would have been allowable under section 38(1)(a) and (b) (acquisition and disposal costs etc) as a deduction in the computation of any gain on a disposal of the acquired interest by the co-owner or co-owners.
