Example sentencesExamples
Once tax relief and Miras were removed it was no longer suitable as the main means of repaying a loan.
But at that time, the first £30,000 of any mortgage - and the majority of those in Scotland - qualified for Miras tax relief, so the real cost of a home loan was even less.
The decreased rate of income tax will cost the Treasury £2.25 billion, but abolition of the married couples allowance and Miras will raise £2.95 billion.
