What should you never rely on the lender for advice about?

The correct answer is related to the principle that lenders are not financial advisors and should not be relied upon for guidance on tax matters.

When it comes to loan structuring, payment schedule changes, and rate changes, while lenders provide important information, they may not present the full picture nor focus on your personal financial strategy. Understanding the tax implications of a mortgage or any associated deductions is complex and varies based on individual circumstances. A tax advisor or accountant has the expertise to provide detailed insights into how a mortgage impacts your tax situation, including deductions, credits, and potential liabilities. Therefore, making financial decisions based solely on advice from a lender, especially concerning something as crucial as tax implications, can lead to uninformed or disadvantageous choices.

In summary, the lender plays a vital role in the financing process, but when it comes to the nuances of tax implications, seeking advice from a qualified tax professional is essential to ensure you're making well-informed decisions regarding your financial obligations.
