Rent vs Buy in 2026: What Today’s Rates Do to the Math
Last updated July 18, 2026
As of July 2026, with 30-year mortgage rates holding in a mid-6% to 7% band, renting and investing the difference beats buying in most mid-priced US markets: our model puts the gap at roughly $67,000 over ten years on a typical $420,000 home versus a $2,100 rental. A drop to 5.5% would turn that into a near coin flip, and 4% would flip it to buying outright. Everything below is date-stamped, so you know exactly which numbers to re-check when conditions move.
Where do rates, prices, and rents stand in mid-2026?
As of July 2026: 30-year fixed mortgage rates sit in a mid-6% to 7% range, national home-price growth has cooled to low single digits, and national asking-rent growth is running around 2-3% a year. Of those three inputs, the mortgage rate dominates the rent-vs-buy verdict — by a wide margin.
Some context for those figures. Rates are below the October 2023 peak, when Freddie Mac’s weekly survey printed just under 7.8%, but still more than double the sub-3% loans of 2021. Rent growth has settled from its double-digit 2021-22 spike back into a boring long-run range, and price growth varies widely by metro — national averages should set your priors, not your answer. As for why the rate dominates: in the default scenario below, principal and interest is $2,124 of the owner’s $3,067 true monthly cost, and each point of rate moves that payment by roughly $200-230 a month on a $336,000 loan. No other input swings the monthly math that hard.
What does a 6.5% mortgage do to the rent-vs-buy math?
At 6.5%, our model’s default US scenario — $420,000 home, 20% down, $2,100 comparable rent, ten-year stay — has renting and investing the difference ahead by about $67,000. The owner’s true first-year cost is $3,067 a month against the renter’s $2,115, and that roughly $950 gap, invested at 7%, is what decides it.
The assumptions, in full: 3% home appreciation, 2.5% rent growth, 7% total investment return, standard deduction. The owner’s $3,067 is principal and interest of $2,124 plus about $943 in property tax, insurance, and maintenance; the renter’s $2,115 is rent plus renters insurance. Crucially, the model treats both sides symmetrically — whichever side is cheaper in a given month invests the difference, where most calculators only credit the renter. That, plus proper tax handling (the standard-versus-itemized delta, 2026’s $40,400 SALT cap, the $750,000 mortgage-interest cap) and full selling costs, is documented in our methodology; the engine behind every number here passes 37 automated tests, including ten independently audited scenarios.
Horizon does not rescue buying at this rate. A 5-year stay has renting ahead by about $49,000 (selling costs bite hard), and a 30-year stay widens the gap to roughly $389,000, because a 7% portfolio compounds faster than a 3% house — even after the mortgage is paid off. If that surprises you, the mechanics are unpacked in when does buying beat renting.
The tipping rent: at what rent does buying start to win?
The tipping rent is the monthly rent above which buying beats renting, holding everything else at our defaults ($420,000 home, ten-year stay). At July 2026 rates near 6.5%, it is $2,468 a month. At 4% it is $1,890; at 8% it is $2,830. Here is the full table from our model:
| 30-year rate | P&I on the $336,000 loan | Tipping rent — buying wins above this | Verdict at $2,100 actual rent |
|---|---|---|---|
| 4.0% | $1,604 | $1,890 | Buying wins |
| 5.0% | $1,804 | $2,067 | Buying wins, narrowly |
| 6.0% | $2,014 | $2,340 | Renting wins |
| 6.5% — July 2026 | $2,124 | $2,468 | Renting wins |
| 7.0% | $2,235 | $2,590 | Renting wins |
| 8.0% | $2,465 | $2,830 | Renting wins |
Our model’s default scenario, 10-year stay; P&I is straight 30-year amortization on the 80% loan.
Read it as a ratio and it travels to any market: each point of rate moves the tipping rent by roughly $175-275 a month, and across our runs, markets where rent is under about 0.5% of the home price per month favor renting at today’s rates, while markets above roughly 0.7% favor buying. Two runs make the spread concrete. A $1.1M home renting at $3,800 (0.35% per month) loses to renting by about $560,000 over 15 years, even for a married couple who itemizes. A $220,000 home renting at $1,600 (about 0.73%) flips to buying. If ratio thinking is new to you, the price-to-rent ratio is the annual version of the same idea, and the 5% rule is its quick-and-dirty cousin.
What would a drop to 5.5% change?
On the default scenario, 5.5% cuts the payment from $2,124 to about $1,908 — $216 a month — and pulls the tipping rent from $2,468 down to roughly $2,200 (interpolating between our model’s 5% and 6% runs). Against $2,100 market rent, that turns a clear renting verdict into a near coin flip.
Go further and the flip completes: at 4%, buying wins the default scenario by about $38,000 and breaks even in year six. Note what our sensitivity runs say about trusting each verdict, though. At 6.5%, no single one-point change to any assumption — appreciation, rent growth, investment return, the rate itself — flips the renting result; it is robust. At 4%, one point of appreciation or rate does flip it. High-rate verdicts are sturdy; low-rate verdicts are the ones to stress-test.
Should you lock a rate now or wait for something lower?
If you have decided to buy and are only choosing when, waiting is a bet that rates fall faster than prices rise. On our default assumptions, two years of 3% price growth lifts the house to about $445,600 — so even landing 5.5% then means a $2,024 payment, versus $1,908 for buying now at 6.5% and refinancing later.
The waiting path also needs about $5,100 more down ($89,100 versus $84,000). But fair is fair: if prices stall or dip while rates fall, waiting wins on both ends, and nobody forecasts either reliably. That is exactly why the tipping table is more useful than a rate call — it only needs today’s rent and today’s quote. And at July 2026 rates, renting while you wait is not dead money: renting is the winning column by $67,000 in the default scenario, so a renter sitting below the tipping rent is not paying for patience.
How much is the refinance option worth?
A fixed-rate mortgage is a one-way bet: if rates fall, you can refinance down; if they rise, you keep 6.5% for three decades. If 5.5% arrives, refinancing the default loan saves $216 a month, which repays a $7,000 closing bill (a middle-of-the-road hypothetical for a loan this size, not a quote) in about 32 months.
That option has real value, but it is not a plan. Underwrite the purchase at the rate you actually lock. If the deal only pencils at a hoped-for 5.5%, the table says your rent sits between roughly $2,200 and $2,468 in tipping terms — the genuinely marginal zone, where the honest answer is “it depends on rates nobody can predict.”
What should you do in each rate bracket?
Match your quoted rate and your actual rent against the tipping table; that one comparison does more work than any forecast. Under 5%, buying usually wins at typical rents, but the margin is fragile. Between 5% and 6% it is genuinely close. In today’s 6-7% band, rent unless local rents run near 0.7% of price per month.
- Under 5%. Buying wins the default scenario (about +$38,000 at 4%), but fragilely — one point of appreciation or rate flips it. Run a pessimistic-appreciation case before you celebrate.
- 5-6%. The tipping rent ($2,067-$2,340) straddles typical mid-market rents, so horizon decides. Shorter than about six years, buying rarely wins in our runs at any rate — even at 4%, break-even is year six.
- 6-7% — where July 2026 sits. Renting and investing wins at typical big-metro ratios near 0.5% per month; buying wins in affordable markets where rent runs about 0.7% of price or more, like the $220,000/$1,600 example above. Check your local ratio before accepting the national verdict.
- Above 7%. Tipping rents of $2,590-$2,830 on a $420,000 home are rare outside the highest-yield markets. Buy only for reasons a spreadsheet cannot price — stability, schools, the right to renovate — and price them consciously; the broader framing lives in is it better to rent or buy.
