Rent vs. buy: the break-even math behind the slogans
Two slogans dominate this decision and both are wrong. “Rent is throwing money away” ignores the large share of an owner’s payment that also disappears. “Buying always builds wealth” ignores what it costs to get in and out. The useful question is narrower: at what point does owning this house, in this market, cost less than renting a comparable one?
Compare cost of occupancy, not rent to principal and interest
The mistake that ruins most comparisons is putting rent next to a mortgage payment. The mortgage payment is not the cost of owning; part of it is savings, and several real costs are not in it at all.
- Interest. Gone, exactly like rent. In the early years this is most of the payment.
- Property taxes. Gone, and they rise with assessments. Effective rates vary widely by state — the figure for yours is on your state’s first-time buyer page.
- Homeowners insurance. Gone, and in coastal and wildfire markets it has become a line that moves the whole calculation.
- Mortgage insurance, if you put less than 20 % down — gone until it is cancelled.
- Maintenance and replacement. Roofs, water heaters, HVAC. Budgeting roughly 1 % to 2 % of the home’s value per year is the conventional planning range; older houses run higher.
- HOA dues, where they apply — gone, and they are raised by vote, not by your choice.
- Principal. The only part that is savings rather than cost.
Against that, a renter pays rent and renters insurance, and keeps the down payment invested. Any honest comparison has to credit the renter with what that money earns.
A worked example
Take a $350,000 loan at an illustrative 6 % on a 30-year fixed. Principal and interest come to about $2,098 a month, or roughly $25,180 over the first year. Our payment table for $350,000 at 6 % shows the full amortization and the point where mortgage insurance drops off.
| First-year line | Illustrative amount | Savings or spent? |
|---|---|---|
| Interest | ≈ $20,880 | Spent |
| Principal | ≈ $4,300 | Savings |
| Property taxes (at a 1.1 % effective rate) | ≈ $4,300 | Spent |
| Insurance | $1,500–$4,000, market-dependent | Spent |
| Maintenance reserve (1 % of value) | ≈ $3,900 | Spent |
So of roughly $34,000 to $37,000 spent on housing in year one, about $4,300 becomes equity. The rest is the price of occupying the house — which is the number that belongs next to a year of rent. Taxes, insurance and maintenance are ranges here because they are genuinely local; substitute your own quotes before drawing a conclusion.
The first-year equity illusion
Amortization is back-loaded by design. On that same loan, the balance falls from $350,000 to about $345,700 after twelve payments, and to roughly $325,700 after five years — about $24,300 of principal against some $126,000 in payments. Equity in the early years comes mostly from price appreciation, which is a forecast rather than a schedule. Anyone who tells you a mortgage is “forced savings” is right, but the savings rate in year one is closer to 12 % of the payment than to 100 %.
Transaction costs are what set the break-even
Buying costs money and selling costs more. Closing costs on the purchase commonly run about 2 % to 5 % of the price depending on the state, the loan and the points paid, as our closing costs guide breaks down. Selling commonly runs 6 % to 9 % once agent compensation — negotiable, and negotiated far more explicitly since 2024 — transfer taxes, title work and typical concessions are counted. Transfer taxes in particular swing enormously by state.
Put those together and a round trip often costs 8 % to 13 % of the value of the house. That is the hole appreciation and principal have to fill before ownership beats renting. It is why the honest answer to “how long do I need to stay?” is usually somewhere between three and seven years, and why a job that might move in eighteen months is a stronger argument for renting than any interest rate.
The tax line most calculators overstate
Mortgage interest and property taxes are deductible only if you itemize, and the standard deduction is large enough that most households do not. The deduction for state and local taxes — including property tax — is also capped, and the cap has changed with recent legislation, so check the current year’s figure rather than a number from an older article. IRS Publication 936 sets out the rules, including the limits on how much debt qualifies.
The practical effect: for a household that takes the standard deduction, the tax benefit of owning is zero, and a comparison that quietly assumes a 24 % write-off on all interest is overstating the case for buying by thousands of dollars a year.
What tips the decision
Toward renting
- A realistic chance of moving within three years, for work or anything else.
- A down payment that would leave you with no emergency fund. Closing on a house with an empty savings account converts a broken furnace into a credit card balance.
- Unstable or newly self-employed income — worth resolving before applying, as our guide on how much house you can afford explains.
- Rents in your market that are far below the cost of owning a comparable home, which happens routinely in high-price coastal metros.
- Debts you would rather clear first: every dollar of monthly obligation reduces the loan you qualify for anyway.
Toward buying
- You expect to stay past the break-even, with a specific reason — schools, family, a settled job.
- Rent in your area is rising faster than the fixed part of an ownership payment, which never rises on a fixed-rate loan even though taxes and insurance do.
- Down payment assistance or a state program materially changes the entry cost — see down payment assistance.
- You want control: pets, renovations, and no renewal letter every year. This is a legitimate reason and does not need to be dressed up as an investment thesis.
How to run your own number in an evening
- Price a specific house, not a category. Get a real property tax figure from the county and a real insurance quote for that address.
- Add annual maintenance at 1 % to 2 % of the value, and HOA dues if any.
- Subtract the year’s principal — take it from an amortization schedule, not from the payment.
- Compare what remains with a year of rent on a comparable home, plus renters insurance.
- Add the round-trip transaction cost, then ask how many years of the gap it takes to absorb it. That number is your break-even, and it is honest only if you did not assume appreciation.

Frequently asked questions
How many years do I need to stay for buying to pay off?
Commonly three to seven, but it is a calculation rather than a rule. The shorter end applies where rents are high relative to prices and transaction costs are low; the longer end where transfer taxes are steep, rents are cheap relative to prices, or you bought with points and heavy closing costs.
Is renting really throwing money away?
No more than interest, taxes, insurance and maintenance are. In the first year of a typical loan, roughly seven-eighths of the mortgage payment plus every dollar of tax, insurance and repair is money you do not get back. Renting buys flexibility and caps your downside; the trade is that you build nothing.
Should I wait for rates to fall before buying?
Nobody can tell you where rates will go, and a site that claims otherwise is guessing. What is knowable: a lower rate raises what buyers can bid, which tends to push prices up, and a rate you dislike can be refinanced later while a price cannot be renegotiated. Decide on the payment you can carry today.
Does a 20 % down payment matter for this comparison?
It changes the monthly cost, not the underlying logic. Less down means mortgage insurance and more interest; more down means a smaller emergency cushion and money not invested elsewhere. Three-percent-down conventional programs exist precisely so the choice is not all or nothing.
What about buying a home as an investment?
A primary residence is a place to live that happens to hold value; treating it as a portfolio asset invites decisions you would not otherwise make. Research on the user cost of homeownership generally finds that returns depend heavily on holding period, local price trends and transaction costs — the three things a slogan leaves out.
