They all come to about 16,000, leaving a taxable profit of 121,500.

Then came last year's summer budget: landlords could no longer deduct mortgage interest as a cost when working out their taxable profit.

That factor turned the group's taxable profit into a loss of 5.2 billion which would take it out of range of the taxman.

That could add up to a gain of about 72,000, even after allowing for some costs such as improvements - your actual costs may have been greater, trimming the taxable profit.

If the definitions are changed to increase the taxable profit made in one country, it requires that the profit made in another country will be reduced.
