Answer:
$304,720
Step-by-step explanation:
According to the IRS, qualified principal residence indebtedness may include:
1) Debt incurred in order to purchase, build or improve your house or main residence, and the debt is secured by the house or principal residence (mortgage).
Or
2) Any house debt in (1) that is refinanced in order to improve, build or purchase something of your house or principal residence, e.g. you refinance your mortgage in order to build a swimming pool. The loan balance cannot exceed the original mortgage.
A fishing boat is not considered a home improvement, so the equity loan is not considered qualified residence indebtedness.
