The "front-end" part of the debt-to-income ratio measures the maximum amount of which of the following?

The "front-end" part of the debt-to-income ratio specifically assesses the portion of a borrower’s gross monthly income that is allocated to housing expenses. This typically includes costs such as mortgage payments, property taxes, homeowners insurance, and any applicable homeowners association fees.

Focusing on this aspect helps lenders evaluate a borrower's ability to manage their monthly housing-related costs in relation to their overall income, which is essential for determining if a borrower can comfortably afford a mortgage payment without overstretching their finances.

Other options, while related to income, either look at net income or broader financial considerations that are not specifically confined to housing expenses. Understanding the distinction of the front-end ratio emphasizes its role in housing affordability assessments, making it a crucial aspect for both lenders and borrowers in financial planning.
