Rent vs. Buy: The Uncomfortable Math
AHOXY Finance
The Biggest Purchase of Your Life
Common wisdom says: "Rent is simple. Buying is an investment." But mathematically, it's distinctively complex.
The Case for Buying
- Forced Savings: Paying down a mortgage प्रिंसिपल is essentially saving money in an illiquid asset.
- Leverage: You can control a $500k asset with only $100k down. If the home appreciates 5%, your ROI is 25%.
- Stability: No landlord can kick you out.
The Case for Renting
- The Hidden Costs of Owning: Property tax, maintenance (1% rule), insurance, and HOA fees. These are "throwaway" costs just like rent.
- Opportunity Cost: If you took that $100k down payment and invested it in the S&P 500 (avg 8-10% return), it might outperform the house appreciation (avg 3-4% real return).
- Mobility: You can move for a better job instantly.
The Verdict
Buying is not always better financially. It is a lifestyle choice.
- Buy if you plan to stay for 7+ years and crave stability.
- Rent if you value flexibility and can discipline yourself to invest the difference.
