its not a problem if he does not own another property. If he does then of course there can be a liability. however the liability is only on the profit. although the revenue could argue that this is a 'sale undercost' and make the appropriate adjustment. Is the house in joint names? if so he can only be profiting on his own half , also he can claim unused capital gains allowances over the last few years. See a good accountant.(posted 7141 days ago)
