The $800K borrower benefits more from itemizing because their mortgage interest alone exceeds the standard deduction. The $300K borrower may not benefit at all unless they have significant state/local taxes. This is why the "effective" cost of a mortgage depends heavily on your tax situation. 2025 SALT cap: $40,000 (MAGI ≤ $500K).

This is an estimate for educational purposes only. Consult a tax professional for advice specific to your situation. Tax calculations use 2025 federal brackets. SALT cap reflects the One Big Beautiful Bill Act ($40K cap for MAGI ≤ $500K, phasing to $10K for MAGI > $600K). PMI deductibility may vary by tax year.
