Key Findings

01Break-even is the year the buyer’s net worth, net of selling costs, first passes the renter’s invested portfolio
02In the worked example — $400K home, 20% down at 6.1%, $2,200 rent — the crossover lands in month 68, year 5.7
03At $1,800 rent for the same house there is no crossover in 30 years: the gap is narrowest at year 14, then widens
04About $60 a month of market rent separates ‘never breaks even’ from ‘breaks even at year 18’
05Appreciation is the strongest lever: 2.5% pushes break-even to year 9.6, 4.5% pulls it in to year 3.8
06Each extra percentage point of selling cost adds roughly six months — 6% crosses at year 4.6, 10% at year 6.8

What Break-Even Means

Break-even is the year the buyer’s net worth — home value, minus the remaining loan, minus what it costs to sell — first passes the renter’s net worth, which is the portfolio built from the down payment, the closing costs, and every month the two paths cost different amounts. Before that year the renting path is projected ahead; after it, the buying path is. What most write-ups leave out is that the crossover is not guaranteed to exist. At some combinations of price, rent, and return the buyer’s line closes on the renter’s, stops closing, and falls behind again. Knowing which of those two cases you are in matters more than knowing the exact year.

The Worked Example

A $400,000 home, 20% down ($80,000), 6.1% on a 30-year fixed, 3% closing costs ($12,000), 1.1% property tax, 0.30% insurance, 0.5% maintenance, 3.5% appreciation, and 8% selling costs. The renter pays $2,200 a month growing 3% a year and invests the $92,000 the buyer spent on the down payment and closing at 7%, less $3,000 in move-in and move-out costs the calculator charges the renter by default. All in, the buyer’s first year costs $2,573 a month against the renter’s $2,215, and the renter invests that $358 gap too. Run month by month, the renter leads by $34.9K at the end of year 1 and by $5.4K at the end of year 5. The buyer passes in month 68 — year 5.7 — and is ahead by $13.0K at year 7, $46.1K at year 10, and $119.1K at year 15.

When the Crossover Never Comes

Change one input in that example — the rent — and the answer inverts. At $1,800 a month for the same $400,000 house, a price-to-rent ratio of 18.5, the renter is ahead by $39.9K after year 1, still ahead by $31.1K after year 10, and the gap reaches its narrowest at year 14 ($29.6K) before widening again for the rest of a 30-year run. There is no crossover at all. The threshold is sharp: at $1,860 rent the paths cross at year 18, at $1,880 at year 15, at $2,000 at year 8.8. Roughly $60 a month in what the same house rents for separates a crossover that never arrives from one that arrives in year 18. In this example the tipping point sits near a price-to-rent ratio of 18 — above it, the carrying cost plus the opportunity cost of the down payment outrun what equity and appreciation add.

Sensitivity to Key Variables

Holding the worked example at its year 5.7 crossover and moving one variable at a time: appreciation at 3.0% pushes break-even to year 7.3 and at 2.5% to year 9.6, while 4.0% pulls it in to year 4.6 and 4.5% to year 3.8. The renter’s assumed return pulls the other way and pulls hard — 5% gives year 4.4, 7% gives year 5.7, 9% gives year 8.8. Selling costs move it about six months per percentage point: 6% gives year 4.6, 10% gives year 6.8. Rent growth is the mildest of the four, with 2% giving year 6.3 and 4% giving year 5.3. None of these is a small effect and they compound, which is why a single-point break-even estimate is really a claim about half a dozen assumptions at once.

The Year-by-Year Reality

Every scenario that does cross has the same shape. Year 1 is the buyer’s worst year by a wide margin: $12,000 of closing costs is spent, 83% of the first year’s mortgage payments went to interest rather than principal, and $33.1K of selling cost is subtracted from the house before the buyer’s net worth is counted — which is how a $414,000 home with $97.9K of gross equity shows as $64.7K. From there the buyer gains on three fronts at once: principal repayment accelerates, appreciation compounds on the whole house rather than on the equity, and the fixed payment falls further behind rising rent each year. In the worked example the gap closes by $6.5K in year 2 and by $8.2K in year 5, crosses in year 6, then opens in the buyer’s favour at an accelerating rate.

Year-by-Year Net Worth Comparison

$400K home · 20% down · 6.1% fixed 30-yr · 3.5% appreciation · 7% investment return · $2,200 rent growing 3% · 8% selling costs. Buyer net worth is net of selling costs in that year.

THE BOTTOM LINE
Break-even isn’t a property of housing, it’s a property of your assumptions. The same $400,000 house crosses at year 5.7 against $2,200 rent and never crosses at all against $1,800. Run your own numbers before trusting anyone’s rule of thumb, this article’s included — DwellQ shows the crossover visually and lets you move every input behind it.

Frequently Asked Questions

How long do I need to live in a home to break even?+
In this article’s worked example — $400K home, 20% down at 6.1%, 3.5% appreciation, $2,200 rent — month 68, or year 5.7. That number belongs to those inputs and no others. Hold everything else and drop the rent to $1,800 and the crossover never arrives in 30 years. The popular ‘five year rule’ is one scenario’s answer being quoted as a law.
Can the two paths never cross at all?+
Yes, and it is not a rare case. Where a house is expensive relative to what it rents for, the carrying cost plus the opportunity cost of the down payment can outrun what equity and appreciation add — permanently. At $1,800 rent against a $400,000 house, a price-to-rent ratio of 18.5, the renter’s lead narrows to $29.6K at year 14 and then widens again. At these rates and returns the tipping point in that example sits near a price-to-rent ratio of 18.
What makes break-even shorter?+
Higher appreciation is the strongest single lever: in the worked example, 4.5% instead of 3.5% pulls break-even from year 5.7 in to year 3.8. Lower selling costs come next, worth roughly six months per percentage point — 6% crosses at year 4.6 against 8%’s year 5.7. Faster rent growth helps as well, moving year 5.7 to year 5.3 at 4%. A lower assumed investment return shortens it too (5% gives year 4.4), but that is a change in what you expect from markets, not a lever you control.
What if I need to sell before break-even?+
You end up with less than if you had rented and invested the same money. In the worked example, selling at year 3 leaves the buyer at $100.3K against the renter’s $121.6K — a $21.3K shortfall, most of it the $12,000 in closing costs and the 8% selling cost that has not been earned back yet. That arithmetic, not sentiment, is why planners tell you to buy only if you expect to stay put.

METHODOLOGY
DwellQ research uses a net worth comparison framework. Both paths—buying (building equity minus all ownership costs) and renting (investing the down payment plus monthly surplus)—are modeled month-by-month over the full holding period. Assumptions are documented, sensitivity-tested, and sourced from publicly available data. This is scenario analysis, not financial advice. Data sources and refresh dates →
