The purchase price of a home is deceptive. When factoring in the total interest paid over a 30-year mortgage, the actual cost can be nearly double the initial price. For a $500,000 home, an additional $400,000 could be spent on interest alone, dramatically altering the long-term financial reality of ownership.

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.

Whether one owns a home is a primary determinant of their perception of affordability. Homeowners with fixed mortgages feel more secure due to locked-in housing costs and accumulated equity. Renters, however, face constant rent increases and lack this wealth-building asset, making them feel far more financially insecure.

Buying a house, especially the largest one you can afford, locks up capital and incurs numerous hidden costs beyond the mortgage (maintenance, taxes, renovations). This inflates your cost of living and hinders wealth creation compared to the simplicity and lower costs of renting.

The current housing market shows an unprecedented 40% cost advantage for renting over owning a home. This massive gap presents a significant headwind for new multi-family construction, as developers would need 25-30% rent growth for projects to be financially viable, an unlikely scenario in a soft market.

The gap between existing mortgage rates (under 4.25%) and new rates (over 6.25%) is over 200 basis points. This spread, which disincentivizes homeowners from selling, has persisted for three consecutive years. Historically, the gap only exceeded 100 basis points for a total of eight quarters over the past four decades, making the current situation a major anomaly.

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.

The idea that renting is "throwing money away" is flawed. Rent is payment for a service that provides shelter, flexibility, and insulation from the risks and hidden costs of homeownership like surprise repairs, property taxes, and maintenance. This "optionality" is a powerful, though non-tangible, financial asset.

Extending mortgage terms doesn't solve housing affordability because it primarily boosts demand for a fixed supply of homes. This drives asset prices higher, as sellers adjust prices to match buyers' new monthly payment capacity. The historical example of Japan's housing bubble, fueled by 100-year mortgages, illustrates this danger.
