Q 1: For the first part of the question the loan would qualify as a tax deduction because its under the $100K yearly total; 420K - 340K = 80K. So he can deduct up to 80,000 meaning hell have to pay interest on the remaining 10,000 of the 90,000? And I assume it would on the schedule A form along with the $6,800 and $9,000?

Q 2: I assume its $10,000 + $16,000 = $26,000 in charity deductions?
