# Rent vs buy: how to compare them fairly

A rent vs buy decision is a comparison of two sets of costs you never get back, plus what your savings could earn in the meantime. Last reviewed November 11, 2026.

## Compare costs that never come back

Rent is the obvious unrecoverable cost of renting. Owning has its own: mortgage interest, property tax, homeowners insurance, maintenance, HOA dues, private mortgage insurance on a small down payment, and the transaction costs of buying and later selling. Principal is different, because it builds equity you keep when you sell.

The CFPB notes that private mortgage insurance is usually required on a conventional loan with less than 20 percent down, and that it protects the lender, not you. [1](#fn1)

## Time in the home matters most

Closing costs and selling costs are paid once each. Spread over two years they are heavy; spread over twelve they are light. That is why the calculator reports the year buying pulls ahead. If you are likely to move before that year, renting usually wins on the numbers.

## Count what your cash could earn

A down payment is money that could otherwise be invested. A fair comparison gives the renter that money to invest, along with any month when renting is cheaper than owning. The calculator does this, and gives the buyer the savings in months when owning is cheaper.

## Beyond the math

- Stability: owning lets you stay as long as you can pay; renting depends on a lease.
- Flexibility: renting makes a job move or a change in household easier.
- Risk: owners carry repair bills and price swings; renters carry rent increases.
- Readiness: lenders look at your debt-to-income ratio, which the CFPB defines as monthly debt payments divided by gross monthly income. [2](#fn2)

## Questions

### Is it always better to buy than to rent?

No. Renting can come out ahead when you will move within a few years, when homes cost a lot relative to rents in your area, or when owner costs such as tax, insurance, and HOA dues are high.

### Is rent just throwing money away?

Rent buys housing, flexibility, and someone else carrying repair risk. Owning has unrecoverable costs too: interest, property tax, insurance, maintenance, and the costs of buying and selling. The fair comparison is unrecoverable cost against unrecoverable cost.
