Answer:
qualified acquisition debt = $750,000
qualified home equity debt = $0
Explanation:
Qualified acquisition debt refers to the debt incurred to purchase or build your home. In this case, Cary and Bill are allowed to itemize the interests paid for up to $750,000 of the acquisition debt ($375,000 if filing separately). This limit was reduced due to the TCJA of 2017, and will remain in place until 2025. After 2025, the limit will return to the normal $1,000,000.
Certain amount of interests on qualified home equity loans will also return in 2025, but currently they are not deductible.
