The What's New bullet discussing the limit on mortgage interest deduction should read:
For indebtedness incurred after December 15, 2017, the deduction for home mortgage interest is limited to interest on up to $750,000 of home acquisition indebtedness. This new limit doesn’t apply if you had a binding written contract on or before December 15, 2017, to close on a home before January 1, 2018, and actually did close before April 1, 2018. The prior limit would apply instead. Special rules also apply to maintain the prior limit if a homeowner refinances the home acquisition indebtedness.
