Renting vs. buying: the real math

'Renting is throwing money away' is the most repeated piece of financial folklore in the United States, and it's mostly wrong. The real comparison isn't rent vs. mortgage — it's the full cost of owning vs. renting, with equity building subtracted from the ownership side and investment returns on the down payment added to the rental side.

The hidden costs of owning

• Property taxes: 1–2% of home value per year, forever. Never goes away.
• Home insurance: 0.3–0.5% of home value per year.
• Maintenance: budget 1% of home value per year long-term, sometimes more.
• Mortgage interest, especially in the first 10 years when principal pays down slowly.
• Closing costs at purchase (2–5%) and sale (6–8%, mostly agent commissions).
• PMI if you put less than 20% down, usually 0.5–1% of loan value per year.

What renting buys you

• Flexibility to move without paying 6% to sell.
• No exposure to a volatile asset concentration (your house).
• No surprise maintenance bills.
• The ability to invest your would-be down payment in something else.

When buying clearly wins

You're staying 7+ years, you have a stable job and life situation, the price-to-rent ratio in your city is reasonable (under 20), mortgage rates are lower than what a similar portfolio of stocks + bonds could return, and you want the psychic benefits of ownership. That's when the math, and the life, align.

When renting clearly wins

You're unsure about your next 3 years, you're in a high-cost-of-living area with a terrible price-to-rent ratio (ratio over 25 means renting is usually cheaper than owning), mortgage rates are high, and you value flexibility. Nothing wrong with that. Renting is not failure — it's a different answer to the same question.
