How rent vs buy comparisons work

Buying costs

Buying includes mortgage payments, taxes, insurance, maintenance, transaction costs, and selling costs.

Renting costs

Renting mainly includes monthly rent and rent increases, but it may offer more flexibility.

Upfront cash

Down payment and closing costs are major cash outflows that could otherwise be invested.

Home equity

Equity can grow from principal repayment and appreciation, but appreciation is not guaranteed.

Comparison

Renting vs buying trade-offs

Renting

Flexibility

Renting can be easier for shorter time horizons, uncertain plans, lower upfront cash, or avoiding maintenance responsibility.

Buying

Equity potential

Buying may become more attractive with a longer stay, strong appreciation, manageable mortgage cost, and stable ownership expenses.

Cost drivers

What affects the break-even point

Time horizon

Longer stays give equity and appreciation more time to offset transaction costs.

Mortgage rate

Higher rates increase mortgage payments and interest cost.

Taxes and maintenance

Ongoing ownership costs can materially change the comparison.

Rent growth

Faster rent increases can make buying more competitive over time.

Home appreciation

Appreciation can improve buying outcomes, but home values can also stagnate or fall.

Transaction costs

Closing and selling costs can make buying less attractive for short stays.

Formula

Rent vs buy formula explanation

Net buying cost

Buying Cost = Cash Outflows + Opportunity Cost − Home Equity

Buying cost includes mortgage payments, down payment, taxes, insurance, maintenance, fees, selling costs, and opportunity cost.

Renting cost

Renting Cost = Sum of Monthly Rent Over Time

Rent is increased each year by the rent growth rate entered in the calculator.

Cost difference

Difference = Renting Cost − Buying Cost

A positive difference means buying is cheaper under the assumptions. A negative difference means renting is cheaper.
