Rent vs Buy: A Practical Framework
Buying is not automatically smarter than renting — it depends on how long you stay, price-to-rent ratios, and the hidden costs of ownership. Here is how to think about it clearly.
The 5% rule of thumb
Unlevered, owning a home costs roughly 5% of its value per year: ~3% opportunity cost of the capital tied up, ~1% maintenance, ~1% property tax (varies by area). If annual rent for a comparable place is less than 5% of the purchase price, renting is often the better financial deal.
Example: a $400,000 home costs about $20,000 a year to own before mortgage interest. If you can rent the same place for $1,500 a month ($18,000 a year), renting wins on pure numbers. Run your own figures through the rent vs buy calculator.
Time horizon is everything
Buying has large fixed costs — closing fees, agent commissions, moving — that only amortize if you stay put. The breakeven is typically 5–7 years. If you might move in 2–3 years for work or life changes, renting is almost always cheaper and far more flexible.
Mortgage amortization helps long stayers: early payments are mostly interest, but each year shifts more toward principal, building equity. Check the yearly schedule on the mortgage calculator to see this in action.
Count the invisible costs
Renters compare rent to the mortgage payment and conclude buying wins. But owners also pay maintenance (budget 1% of value yearly), insurance, property tax, HOA fees, and the opportunity cost of the down payment. Add 30–50% on top of principal-and-interest for the real monthly number.
It is not only math
Ownership buys stability, control, and forced savings — real value that spreadsheets underrate. Renting buys mobility and freedom from repair bills. Decide with the numbers first, then let lifestyle break the tie — not the other way around.
