Proposals to allow homeowners to take their low-rate mortgages with them (portability) or transfer them to a buyer (assumability) cannot be retroactively applied due to contract law. Creating new mortgages with these features is possible, but the added benefits to the borrower would likely result in a higher, not lower, interest rate.

Home ownership is reframed as a high-risk financial instrument, not a safe investment. A mortgage constitutes a 5-to-1 levered, highly concentrated, non-cash-flowing bet on the economic future of a single zip code, making it far riskier than a diversified public market portfolio.

Not all debt is negative. Using leverage to acquire assets that generate returns—like real estate, inventory, or business investments—is a smart wealth-building tool. Conversely, financing depreciating lifestyle items ('flexing') creates a financial hole that's nearly impossible to escape.

The proposal of a 50-year mortgage is not a solution but a symptom of a deeply unhealthy economy. It's like giving insulin to a diabetic: it manages the immediate problem (unaffordable payments) without addressing the root cause (a severe lack of housing supply and inflationary pressures).

Common wisdom to rapidly pay off a mortgage is suboptimal. Due to compounding, investing extra cash—even if the return rate merely matches your mortgage interest—will generate significantly more wealth over time. One investment compounds up while the other debt amortizes down, creating a large wealth gap.

A proposed 50-year mortgage, intended to improve housing affordability, is a flawed solution. The extended term means borrowers build equity at a negligible rate, making the financial outcome similar to renting and failing to deliver the key wealth-building benefit of homeownership. It's a demand-side fix for a supply-side problem.

While a 50-year mortgage could significantly lower monthly payments to aid affordability, it has a major drawback. The total interest paid over the life of the loan would likely be double that of a traditional 30-year mortgage. This prohibitive cost, along with technical challenges, would likely suppress borrower demand for such a product.

Most consumer fintech products—payments, personal loans, investing—are merely means to an end. The ultimate goal for most consumers is achieving generational wealth, which is fundamentally tied to homeownership. This reframes the entire fintech ecosystem as a funnel leading to the housing market.

For those who can afford a down payment but not the monthly mortgage, Emma Hernan suggests a "buy and rent" strategy. Purchase the property, place a tenant in it to cover the mortgage payments, and build equity. You can then move in years later when your financial situation improves.
