# 5-Year Crossover: Buy Starter Home (7% Rate) vs Rent & Index Fund

> Comparing buying a home at a 7 percent mortgage rate versus renting and investing in index funds reveals a critical 42-month break-even timeline. High upfront transaction costs of 6 percent for purchasing heavily weigh down early years, but equity accumulation and 3 percent property appreciation typically overtake rental inflation by month 48, making homeownership financially superior for timelines exceeding 5 years.

- **Major Bear Market (-25%):** Stock market downturn severely impacts index fund portfolio performance.
- **Local Rent Surge (+15%):** Regional housing shortage drives local rental rates up sharply at lease renewal.

## Frequently Asked Questions

### How does a 7% mortgage rate impact the 5-year break-even point?
A 7% interest rate front-loads your amortization schedule with interest payments, pushing the traditional break-even crossover point out to approximately 42 to 48 months compared to historical 4% rate environments.

### What happens if I need to sell my starter home before Year 3?
Selling before 3 years almost always results in a net financial loss due to transaction friction, specifically the standard 6% real estate agent commissions and closing costs which outpace short-term appreciation.

### Does renting and investing beat buying if the stock market returns 10%?
If index funds consistently return 10% or higher while home appreciation remains flat at 2%, renting and investing can win even past Year 5. However, forced savings through home equity typically protects against lifestyle inflation.
