The mortgage industry optimized for affordability. It ignored capital efficiency.

"The 30-year fixed-rate mortgage became the dominant structure because it lowers monthly payments, expands borrower eligibility, and fits cleanly into underwriting frameworks built around debt-to-income ratios."

"Lower monthly payments do not mean lower cost. They mean the cost is extended over time, increasing total interest paid and slowing equity accumulation."

"The modern mortgage system treats amortization as the default path to financial progress, depending on assumptions of long-term property ownership and stable income."

"Amortization becomes inefficient when it does not align with the borrower's intent, particularly for those expecting to sell within five to seven years."

The mortgage lending industry has focused on making homeownership affordable through the 30-year fixed-rate mortgage, which lowers monthly payments. However, this structure increases total interest paid and slows equity accumulation. The traditional model assumes long-term ownership and stable income, but these assumptions are becoming less reliable as borrowers move frequently and prioritize liquidity. The current system defaults to amortization, which can misalign with borrowers' intentions, particularly for those planning to sell within a few years, resulting in inefficiencies.
