First, home buyers need to understand that deductions for mortgage interest are now capped at home acquisition debt of $750,000. This can add to the costs of buying homes in expensive housing markets where home prices top that number.
It’s interesting to note that the $750,000 limit applies to single taxpayers as well as married couples. According to a prior ruling of the Ninth Circuit Appeals Court, when two unmarried people buy a home together, they can combine their limits and deduct the mortgage interest on debt up to $1.5 million.
