What is the opportunity cost of buying a resale home?

The opportunity cost is the wealth you lose because the resale maintenance premium (2-3.5% of value vs 0.5-1.5% for new) cannot be invested. On a $400K home over 25 years, that premium totals $150K-$300K in raw spending and $400K-$800K+ when you factor in compounded market returns the money would have earned.

How does the maintenance premium compound over time?

Each year's extra maintenance cost on a resale home is money that could have been invested. A $4,000 annual premium invested at 7% for 25 years grows to over $12,000. Across all 25 years, the cumulative compounded opportunity cost typically exceeds the raw premium by 2-3x.

Is renting better than buying a resale home?

In many markets, renting and investing the difference (down payment + monthly savings) outperforms buying a resale home. The rent-vs-buy calculation depends on local rent levels, home appreciation, maintenance costs, and investment returns. This calculator models all three paths side by side.

Why does home age matter so much for net worth?

A 20-year-old home needs roof replacement, HVAC overhaul, and plumbing repairs within the first decade of ownership. These costs run 2-3.5% of home value annually vs 0.5% for a new build. That 1.5-3% gap applied to a $400K home is $6,000-$12,000 per year that cannot compound in the market.

What is the 4% rule and how does it relate to the maintenance premium?

The 4% rule states you can withdraw 4% of your portfolio annually in retirement without running out of money. The compounded opportunity cost of a resale maintenance premium often represents $1,000-$3,000+ per month in passive income you will never receive, directly reducing your retirement quality of life.
