Rent vs Buy at 6.5%: Break-even Stretched From 5 Years to 9
The rent-vs-buy answer changed in 2024-2026, and most of the advice on the internet hasn’t caught up.
We ran a $400,000 home through the calculator at 2021 rates (3%) and 2026 rates (6.5%). The break-even year — when buying overtakes renting in net wealth — moved by 4 years.
What the break-even year actually looks like
Same $400K home, same 20% down, same 30-year fixed. Only the mortgage rate changes:
| Mortgage rate | Monthly P&I | Break-even (buy wins) |
|---|---|---|
| 3.0% (2021) | $1,348 | Year 5 |
| 4.5% (long-run avg) | $1,621 | Year 7 |
| 6.5% (2026) | $2,022 | Year 9 |
| 7.5% (peak) | $2,237 | Year 11 |
A 3.5 percentage point rate increase added 4 years of break-even time. The interest portion of every monthly payment is bigger, the equity portion is smaller, and the opportunity cost of the renter’s invested down payment is unchanged.
If you’re holding 7+ years, buying still wins. If you might move in 5 years, renting now wins by a meaningful margin. The “5-year rule of thumb” from sub-3% rates is wrong for 2026.
The full ownership cost on a $400K home
We ran the line items:
| Cost | Annual | Monthly |
|---|---|---|
| Mortgage P&I (6.5%, 30yr, 20% down) | $24,264 | $2,022 |
| Property tax (1.1% national avg) | $4,400 | $367 |
| Maintenance (1% of home value) | $4,000 | $333 |
| Insurance | $1,800 | $150 |
| HOA (when applicable) | $3,600 | $300 |
| Cash outflow per month | $3,172 | |
| Forgone return on $80K down (7% real) | $467 | |
| Total economic cost | $3,639 |
The “$2,022 mortgage” people quote is 56% of the actual monthly economic cost. The rest — tax, maintenance, insurance, HOA, opportunity cost — is the part that makes “I bought because rent is throwing money away” a misread of the math.
Some of that $3,639 builds equity (the principal portion of the mortgage payment). Most of it doesn’t.
When the renter actually wins
Comparing to a $2,800/month rental (typical for a $400K-equivalent property at 8.4% gross rent yield):
- Renter pays $2,800/month
- Owner pays $3,172/month in cash + has $80K locked up
- Difference invested by renter: ($3,172 − $2,800) × 12 + $80K initial = ~$84,500 invested in year 1, growing each year
At 7% real return over 10 years, that compounds to roughly $160,000 of investment portfolio for the renter. Meanwhile the owner has accumulated about $35K of equity from principal payments + ~$85K of price appreciation (3% annual on $400K = ~30% over 10 years), netted against $24K in selling costs at exit.
The numbers work out roughly even at year 9 in this specific case, with home appreciation rate doing most of the heavy lifting on the buy side. Drop home appreciation to 1.5% and break-even moves to year 12+. Push it to 4.5% and break-even returns to year 6-7.
What changes the answer
Five inputs that actually move the break-even year:
- Local price-to-rent ratio. Above 25 (San Francisco, NYC, parts of LA) → renting often wins outright over 10-year windows. Below 15 (Pittsburgh, Cleveland, much of the Midwest) → buying wins at year 5-6.
- Expected hold period. Most decisive variable. Under 5 years almost always favors renting at 2026 rates. Over 10 years almost always favors buying.
- Local rent growth. 5%+ annual rent growth (Austin pre-2023, parts of Florida) pulls break-even forward by 1-2 years. Flat rent (post-correction markets) pushes it back.
- Down payment alternative use. If you’re not actually going to invest the saved down payment, the opportunity cost is theoretical. The math collapses; buying wins by default.
- Tax treatment. Mortgage interest deduction matters less now than pre-2017 (higher standard deduction). For most middle-income households the deduction is functionally zero. High-income households in high-tax states still get meaningful benefit.
Where this scenario doesn’t hold
- Family stability needs. A school district, a 30-year mortgage giving fixed housing costs, control over renovations — these have non-financial value not captured in net worth math. A 9-year break-even isn’t a 9-year prison sentence; it’s the point where the spreadsheet catches up to the lifestyle reasons you might have already preferred buying.
- Cash buyers. No mortgage, no opportunity cost on down payment in the same way. The math becomes: forgone return on full purchase price vs rent saved + appreciation. Different break-even structure entirely (usually shorter).
- Investment property. Rental income changes everything. This article is about owner-occupied. For investment use the cap rate / cash-on-cash return framework instead.
- Speculative appreciation markets. If you genuinely believe local home prices will appreciate 6-8% annually (some Sunbelt markets), buying wins at year 5-6 even at 6.5% mortgage rates. The “if” is doing a lot of work in that sentence.
What to actually do
Run your real numbers. The defaults that worked in 2021 don’t work now, and the defaults that work nationally don’t work in your specific market.
Open the Rent vs Buy Calculator → and override mortgage rate, home appreciation, rent growth, and investment return. The break-even year is the only output that matters; everything else is intermediate.
