Renting vs. Buying

Different cost shapes, not different totals

Renting is a smooth, predictable cost that rises with the market. Buying front-loads a large cash outlay, then produces a payment that is partly consumption (interest, taxes, insurance, maintenance) and partly savings (principal).

Comparing only monthly rent to a monthly mortgage payment is the most common mistake. The correct comparison includes upfront cash, ongoing non-loan costs, equity built, and what happens when you leave.

The variables that decide it

Small changes in these inputs move the answer more than anything else.

• How long you stay — transaction costs of buying and selling are large and fixed
• Rent growth in your market
• Home price appreciation, which is uncertain and regional
• Interest rate at purchase
• What you would do with the cash if you did not buy

What buying gives you that a spreadsheet misses

Control over the property, insulation from rent increases, and a forced savings mechanism. Against that: illiquidity, maintenance responsibility, concentration of net worth in one asset, and reduced mobility.

How to use the calculator

Run the Rent vs. Buy Calculator with your real numbers, then run it again with pessimistic assumptions — lower appreciation, higher maintenance, a shorter stay. If buying still holds up, the decision is robust. If it only works under optimistic inputs, that is useful information too.
