"Should I rent or buy?" is one of the biggest financial questions most people ever face — and the honest answer is: it depends on your numbers and your timeline. This guide walks through the factors that matter most, so you can use the calculator with confidence.
1. Your time horizon is everything
The single biggest driver of the rent-vs-buy decision is how long you'll stay. Buying carries large one-time costs — roughly 2–5% to buy and 6–8% to sell. Those costs are spread across the years you own the home. Stay two years and they wreck the math; stay ten and they barely register. As a rough rule, if you won't stay at least five years, renting is usually the safer bet.
2. The price-to-rent ratio
Divide a home's purchase price by the annual rent for a similar home. A ratio under about 15 generally favors buying; above 21 strongly favors renting; in between, it's a toss-up that depends on the other factors below. It's the quickest sanity check before you run any numbers.
3. The costs people forget
- Maintenance: Budget roughly 1% of the home's value per year. Roofs, HVAC, and appliances fail on their own schedule, not yours.
- Property taxes: Vary wildly by location — from under 0.5% to over 2% of value per year.
- HOA fees: Condos and many communities charge monthly dues that can rival a tax bill.
- Opportunity cost: A down payment invested elsewhere could be growing. Renting keeps that money liquid.
4. The break-even point
The break-even point is the year when buying becomes cheaper than renting on a total-cost basis. Before it, renting is ahead; after it, owning pulls away. Our calculator shows this as the year the two lines cross. Find that year, then ask yourself honestly: will I still be here?
5. The factors no calculator captures
Money isn't the whole story. Owning offers stability, freedom to renovate, and protection from rent hikes. Renting offers mobility, predictable costs, and freedom from maintenance headaches. Weigh the financial answer against how you actually want to live.
