In this archival episode, Kris Krohn demystifies the mortgage underwriting process by introducing the ".43 rule" for Debt-to-Income (DTI) ratios. He explains how your gross monthly income determines your maximum debt allowance and explores the political winds that could shift property qualifications away from personal finances and onto the real merit and profitability of the investment asset itself.
