Rent vs Buy a Home in 2026: The Math Behind the Decision
Whether renting or buying wins depends on your mortgage rate, how far rent sits below the cost of owning the same home, and how long you stay. At the 7.03% average 30-year rate Freddie Mac reported on September 24, 2026, renting and investing the difference comes out ahead in our 10-year example: a $400,000 home bought with 20% down, compared with renting a similar home for $2,100 a month, leaves the renter about $73,000 ahead.
Buying catches up if your rate is near 5.3% or lower, if the home appreciates about 4.6% a year or more, or if rent for the same home is about $2,480 a month or more. This guide lists every assumption, shows the year-by-year results, and adds a 2026 market snapshot and the tax rules. To test your own numbers, use our Rent vs Buy Calculator.
What Buying Costs Each Month
The mortgage payment is only part of owning. Here is the first year for a $400,000 home with 20% down ($320,000 loan) at a 30-year fixed rate of 7.0%, close to the 7.03% Freddie Mac average:
| Cost | Monthly | Annual | Assumption |
|---|---|---|---|
| Mortgage principal and interest | $2,129 | $25,548 | $320,000 at 7.0% for 30 years |
| Property tax | $300 | $3,600 | 0.9% of home value, the simple average of the 50 state rates (Tax Foundation) |
| Homeowner's insurance | $208 | $2,490 | NerdWallet's $2,490 national average for $400,000 of dwelling coverage |
| Maintenance and repairs | $333 | $4,000 | 1% of home value a year, a common rule of thumb |
| Total (no HOA, no PMI) | $2,970 | $35,638 | Add HOA dues if the home has them |
State property tax rates range from 0.29% in Hawaii to 1.88% in New Jersey and Illinois, so check your county before trusting a national average. With 20% down there is no private mortgage insurance. Then there is the cash you need up front:
| Upfront cost | Amount |
|---|---|
| Down payment (20%) | $80,000 |
| Closing costs (Freddie Mac says 2% to 5% of the price; the model uses 3%) | $12,000 (range $8,000 to $20,000) |
| Cash in the model | $92,000 |
Inspections, moving costs and furnishing are not in the model, so real cash needs run higher. The $92,000 is money that could have stayed invested, which is the opportunity cost of buying. At 7% a year, $92,000 grows to $180,978 in 10 years. Our Mortgage Calculator shows the exact principal and interest for your loan, and the mortgage payment guide explains the formula.
What Renting Costs
Rent for a comparable home starts at $2,100 a month in the model and rises 3% a year. That growth rate sits between Zillow's 2.5% year-over-year rent increase for August 2026 and the 3.0% rise in the BLS shelter index over the 12 months to August 2026.
| Year | Monthly rent | Annual rent | Total rent paid so far |
|---|---|---|---|
| 1 | $2,100 | $25,200 | $25,200 |
| 3 | $2,228 | $26,735 | $77,891 |
| 5 | $2,364 | $28,363 | $133,790 |
| 7 | $2,508 | $30,090 | $193,094 |
| 10 | $2,740 | $32,880 | $288,890 |
Over 10 years the renter pays about $288,890 in rent, and owning the same home costs about $372,556 in payments, taxes, insurance and upkeep. The difference is that part of the owner's payments builds equity. The honest comparison is what each side is worth at the end.
The Real Comparison: What Each Side Owns After 10 Years
The model tracks two households month by month. Both start with the same $92,000 in cash.
- The buyer puts $80,000 down, pays $12,000 in closing costs, and owns a home that appreciates 3% a year. At the end, the buyer's wealth is the home's value minus the mortgage balance minus 6% selling costs (Clever Real Estate's August 2026 survey put the average agent commission at 5.46%, plus other seller costs). If owning ever costs less than renting in a month, the buyer invests the difference.
- The renter invests the $92,000 at 7% a year and, each month, also invests whatever owning would have cost above the rent. Investment returns are before taxes and fees, and 7% is an assumption, not a promise.
Property tax and maintenance are charged on the home's current value, homeowner's insurance rises 3% a year, and the cost table shows first-month figures.
| After | Home value | Mortgage balance | Buyer's wealth after selling costs | Renter's portfolio | Result |
|---|---|---|---|---|---|
| 3 years | $437,091 | $309,526 | $101,339 | $146,289 | Renter ahead by $44,950 |
| 5 years | $463,710 | $301,221 | $134,666 | $186,561 | Renter ahead by $51,895 |
| 7 years | $491,950 | $291,672 | $170,761 | $230,508 | Renter ahead by $59,748 |
| 10 years | $537,567 | $274,600 | $230,713 | $304,209 | Renter ahead by $73,496 |
At year 10 the home is worth $537,567 and the mortgage balance is $274,600, so after $32,254 in selling costs the buyer holds $230,713. The renter's portfolio is $304,209. Owning costs about $870 a month more than renting at the start ($2,970 versus $2,100), and the renter invests that gap.
What Would Change the Answer
Small changes in the inputs flip the result. This table changes one input at a time and shows the 10-year outcome and the first year the buyer's wealth catches up with the renter's (checked out to 30 years):
| Change | Result after 10 years | Buyer catches up |
|---|---|---|
| Base case: 7.0% rate, 3% appreciation, 7% investment return, $2,100 rent | Renter ahead by $73,496 | None in 30 years |
| Mortgage rate 6.0% | Renter ahead by $30,701 | None in 30 years |
| Mortgage rate 5.0% | Buyer ahead by $11,135 | Year 9 |
| Mortgage rate 8.0% | Renter ahead by $117,090 | None in 30 years |
| Home appreciation 2% a year | Renter ahead by $114,922 | None in 30 years |
| Home appreciation 4% a year | Renter ahead by $28,085 | None in 30 years |
| Home appreciation 5% a year | Buyer ahead by $21,640 | Year 7 |
| Investment return 5% a year | Renter ahead by $29,366 | Year 17 |
| Investment return 9% a year | Renter ahead by $124,938 | None in 30 years |
| Starting rent $2,400 | Renter ahead by $15,628 | Year 14 |
| Starting rent $1,800 | Renter ahead by $131,365 | None in 30 years |
| Rent growth 4% a year | Renter ahead by $56,614 | Year 24 |
| Rent growth 2% a year | Renter ahead by $89,557 | None in 30 years |
Holding everything else at the base case, buying breaks even at 10 years when the mortgage rate is 5.3%, home appreciation is 4.6% a year, or starting rent is $2,480. The sensitivity is why any single rule of thumb, including the ones below, should be treated as a first screen.
The Price-to-Rent Ratio
The price-to-rent ratio is the home price divided by a year of rent for a comparable home. In the example, that is $400,000 divided by $25,200, or 15.9.
Price-to-rent ratio = home price / (monthly rent x 12)
Example: $400,000 / ($2,100 x 12) = $400,000 / $25,200 = 15.9A common rule of thumb reads a ratio below 15 as favoring buying, 16 to 20 as a toss-up, and 21 or more as favoring renting. Using Zillow's August 2026 figures for the typical home value and typical rent, the national ratio is about 15.8 ($369,678 divided by $1,948 times 12). Some metros:
| Metro area | Typical home value | Typical monthly rent | Price-to-rent ratio |
|---|---|---|---|
| United States | $369,678 | $1,948 | 15.8 |
| San Jose, CA | $1,544,638 | $3,815 | 33.7 |
| San Francisco, CA | $1,134,525 | $3,409 | 27.7 |
| Los Angeles, CA | $957,612 | $2,941 | 27.1 |
| Denver, CO | $562,732 | $1,922 | 24.4 |
| Atlanta, GA | $377,813 | $1,853 | 17.0 |
| Memphis, TN | $244,845 | $1,400 | 14.6 |
| Chicago, IL | $359,782 | $2,210 | 13.6 |
The rule of thumb depends on the interest rate. In this model, the ratio at which buying and renting tie after 10 years is 16.3 at a 5% rate, 14.8 at 6%, and 13.4 at 7%. At today's rates, a ratio of 15 is not low enough to make buying the clear winner.
The Break-Even Point
The break-even point is the number of years you must stay for buying to leave you as wealthy as renting. Two things slow it down. First, transaction costs are large: in the model, buying costs about 3% and selling about 6% of the home price, roughly 9% round trip, which is about three years of 3% appreciation just to cover them. Second, in the early years most of each payment is interest: only $262 of the first $2,129 payment goes to principal.
In the base case, the buyer does not catch up within 30 years. At a 5% rate the buyer catches up in year 9, and with 5% appreciation, in year 7. In none of the scenarios in the table above does the buyer catch up in fewer than 7 years, so a move within about five years favors renting.

The 2026 Housing Market in Numbers
- Mortgage rates: Freddie Mac's 30-year fixed average was 7.03% on September 24, 2026, up from 6.76% on September 10 and 6.30% a year earlier. Rates move weekly, so check the current figure.
- Prices: the National Association of Realtors reported a median existing-home price of $429,100 for August 2026, up 1.6% from a year earlier and the 38th straight yearly increase, with 4.9 months of supply. Zillow's typical home value is $369,678, up 1.3%.
- Rents: Zillow's typical rent is $1,948, up 2.5% from a year earlier. The BLS shelter index rose 3.0% over the 12 months to August 2026.
- Insurance: NerdWallet's May 2026 national average is $2,490 a year for $400,000 of dwelling coverage, and your quote depends heavily on location.
- Selling costs: Clever Real Estate's August 2026 survey of 434 agents put the average total commission at 5.46%. Since the 2024 NAR settlement, the buyer's agent fee is negotiated separately.
How the Interest Rate Changes the Payment
The rate is the biggest lever on the cost of owning. This is the monthly principal and interest and the total interest on a $320,000, 30-year loan:
| Rate | Monthly principal and interest | Total interest over 30 years | Total paid |
|---|---|---|---|
| 3.0% | $1,349 | $165,688 | $485,688 |
| 5.0% | $1,718 | $298,419 | $618,419 |
| 6.0% | $1,919 | $370,682 | $690,682 |
| 7.0% | $2,129 | $446,428 | $766,428 |
| 8.0% | $2,348 | $525,297 | $845,297 |
At 7%, you pay $280,740 more interest than at 3%, and the total paid is 58% higher for the same house. The gap between 7% and 5% is $411 a month. Compare loan offers side by side with our Mortgage Comparison Calculator.
Taxes: The Deduction and the Sale Exclusion
- Mortgage interest only helps if you itemize. The 2026 standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly (IRS). Mortgage interest is deductible on the first $750,000 of debt, but only on Schedule A.
- In the example, year-1 interest is $22,297 and property tax is $3,600, or $25,897 together. That is below $32,200, so a married couple with no other deductions gets no benefit. A single filer is $9,797 over the standard deduction, which saves about $2,160 in the 22% bracket in year 1 and roughly $16,000 to $20,000 over 10 years. That would not close the $73,000 gap.
- Property tax counts toward the SALT deduction, which is capped at $40,400 for 2026 for most filers, and the cap reverts to $10,000 after 2029.
- Selling a home has a tax break. If you owned and lived in the home for at least 2 of the last 5 years, you can exclude up to $250,000 of gain ($500,000 for a joint return). In the example the gain is about $105,000 after the $32,254 in selling costs (less once qualifying purchase costs are added to your basis), so no capital gains tax is due.

Where Each Option Wins
Buying Tends to Win When
- You will stay 10 years or more, so transaction costs are spread out
- Your local price-to-rent ratio is well below 15, or comparable rent is close to the full cost of owning
- You can get a rate near 5% or lower, or you expect the home to appreciate faster than about 4.6% a year
- You value stability, and a fixed payment for principal and interest matters more to you than the best expected return
- You would not otherwise invest the money that renting frees up
Renting Tends to Win When
- You might move within 5 years
- The price-to-rent ratio is above 20, as in several coastal metros in the table above
- Mortgage rates are high compared with the return you expect on investments, as they are at 7%
- You will really invest the difference in the down payment and monthly costs
- You value flexibility and low maintenance responsibility
The Non-Financial Side
Owning lets you renovate, plant a garden and stay put, and a landlord cannot choose not to renew your lease. Renting gives you the freedom to relocate for work, downsize, or avoid repair bills. The model puts a price on the money side only, and people reasonably weigh the rest differently.
A Five-Question Checklist
- How long will I stay? Under 5 years leans rent. Over 10 leans buy if the ratio and rate cooperate.
- What is the price-to-rent ratio for a comparable home? Use the price of the actual home and the rent for a similar one.
- What rate can I get? Every point matters: 7% versus 5% is $411 a month on this loan.
- Can I afford the cash up front and still keep an emergency fund?
- Will I actually invest the savings if I rent? The renter's advantage only exists if the difference is really invested.

Frequently Asked Questions
Is it better to rent or buy a home in 2026?
It depends on your rate, the price-to-rent ratio, and how long you will stay. At the 7.03% average 30-year rate Freddie Mac reported on September 24, 2026, our 10-year example (a $400,000 home, $2,100 rent) favors renting by about $73,000. Buying only catches up if your rate is near 5.3% or lower, the home appreciates about 4.6% a year or more, or rent for the same home is about $2,480 a month or more. Run your own numbers in a rent vs buy calculator.
What if I can only put 5% to 10% down?
You will usually pay private mortgage insurance (PMI). Freddie Mac puts it at roughly $30 to $70 a month for every $100,000 borrowed, which is $108 to $252 a month on a $360,000 loan (10% down on $400,000). PMI is not permanent: you can ask your servicer to cancel it when your balance is scheduled to reach 80% of the home's original value, and it must end automatically at 78%. A smaller down payment keeps more money invested, but it means a larger loan, a bigger payment, and slower equity growth.
Does the mortgage interest deduction change the math?
Less than most people expect. You only benefit if your itemized deductions beat the standard deduction, which is $16,100 for single filers and $32,200 for joint filers in 2026. On our example loan, first-year interest of $22,297 plus property tax of $3,600 is below $32,200, so a married couple with no other deductions saves nothing. A single filer in the 22% bracket saves roughly $2,160 in year 1, and about $16,000 to $20,000 over 10 years, which does not close the $73,000 gap in this example.
Should I wait for lower mortgage rates to buy?
Nobody can time rates reliably. The Freddie Mac average was 6.30% a year ago, 6.76% on September 10, and 7.03% on September 24, 2026. If rates fall you can refinance, and dropping from 7% to 5% on $320,000 would cut principal and interest by about $411 a month, but a refinance has closing costs and restarts your loan term. Buy when the numbers work at today's rate, not at a hoped-for one, and use a refinance calculator to see the break-even before counting on it.
Isn't building equity a form of forced savings?
Yes, and it is a real advantage for people who would not otherwise invest. On the example loan, about $262 of the first payment goes to principal, growing to about $524 in month 120, and $45,400 of principal is paid off in 10 years, plus whatever the home appreciates. The catch is the cost of getting that equity: interest, taxes, insurance, upkeep and selling costs. A renter who invests the difference builds wealth without those costs, but only if the money is actually invested.
