Rent vs Buy: How to Think About the Break-Even Point
Most rent-vs-buy calculators give you a simple answer: buy, rent, or it's close. But the more useful question is when buying starts to win — the break-even point.
What Is the Break-Even Point?
The break-even point is the year where your net worth from buying exceeds your net worth from renting, assuming you invested the difference in the stock market.
It's not a fixed number. It depends on several factors:
- Home appreciation rate — faster appreciation means buying wins sooner
- Mortgage rate — higher rates mean more money going to interest, not equity
- Investment returns — stronger stock market returns help the renter's case
- Transaction costs — selling a home costs 5–10% of the sale price
- Timeline — a short stay almost always favors renting
Why Timeline Is the Biggest Factor
Transaction costs are the hidden tax on buying. When you sell a home, you pay realtor fees, closing costs, and potentially capital gains. If you sell after just 2–3 years, these costs can wipe out any equity you've built.
A typical home sale costs 6% of the sale price. On a $400,000 home, that's $24,000 gone — before you even count your interest payments.
Our model factors in selling costs at the end of your planned timeline. That's why you'll see a different recommendation for a 5-year stay versus a 15-year stay.
The Opportunity Cost You're Missing
Here's what most people don't consider: the cash you put into a down payment and closing costs could have been invested in the market instead.
If you put $80,000 down on a $400,000 home, that's $80,000 not earning stock market returns. At 7% annual returns over 10 years, that's over $150,000 in potential gains — money you only get back if your home appreciates enough to cover it.
How to Use the Break-Even in Your Decision
- Set your honest timeline. How long do you realistically plan to stay? Not your dream — your honest estimate.
- Run the calculator. See where the break-even falls relative to your timeline.
- If the break-even is past your timeline — renting is likely the safer choice.
- If the break-even is well before your timeline — buying has a strong financial case.
- If it's close — decide based on non-financial factors: stability, customization, schools, lifestyle.
The Bottom Line
The break-even year is the single most useful number in the rent vs buy decision. It tells you how long you need to commit for buying to pay off — and whether your actual timeline supports that commitment.
