About the mortgage interest deduction: The estimated tax savings of $85,359 over 10 years assumes you itemize your deductions rather than taking the standard deduction. For 2025, the standard deduction is $15,000 (single) or $30,000 (married filing jointly). The deduction only provides a benefit if your total itemized deductions exceed the standard deduction. Consult a tax professional for personalized advice.

Actual costs will vary based on market conditions, specific property details, tax situations, and other factors. Home appreciation and investment returns are not guaranteed. Closing costs are estimated at 3% of home price. Contact a financial advisor and mortgage professional for personalized guidance.
