Rent or Buy a House in 2026: The Honest Math

Buying beats renting only if you stay long enough for the house to repay what it costs to get in and out. In the example below, with 2026-style numbers, that takes about eight years. Stay five and renting comes out ahead; stay twelve and buying wins by more than $40,000. Everything else in this guide is about what moves that line.

The two monthly bills

Take a $420,000 house and a similar house nearby that rents for $2,400 a month.

Owning, first year	Per month
Mortgage payment: $336,000 at 6.5% for 30 years	$2,124
Property tax at 1.1% of the price	$385
Homeowners insurance	$175
Upkeep at 1% of the price per year	$350
Total	$3,034

Renting costs $2,400, plus about $20 for renters insurance. Owning costs about $614 more each month.

Some of that gap comes back to you. In the first year, $3,756 of the mortgage payments, about $313 a month, pays down the loan and becomes equity. The rest is interest: $21,729 in year one. Interest, tax, insurance and upkeep are the true costs of owning, just as rent is the true cost of renting.

Buying also costs money up front: the $84,000 down payment plus closing costs of about 3%, or $12,600. That $96,600 could have been invested instead, and that lost return is a real cost of owning too.

Year by year: when buying pulls ahead

To compare fairly, follow two people from the same starting point:

• The buyer puts $96,600 into the house and pays the monthly costs. The home gains 3% a year. When the buyer sells, 7% of the price goes to agents and closing costs.
• The renter invests the same $96,600 and, each month, the difference between the buyer’s costs and the rent, earning 5% a year. Rent rises 3% a year.

End of year	Buyer’s equity after selling costs	Renter’s investments	Ahead
1	$70,074	$109,137	Renter by $39,063
3	$102,857	$134,334	Renter by $31,477
5	$138,280	$159,582	Renter by $21,303
8	$196,914	$197,188	Renter by $274
10	$240,086	$221,795	Buyer by $18,291
12	$286,898	$245,760	Buyer by $41,138

The buyer starts far behind because closing costs and the eventual cost of selling eat the early equity. The gap closes as the loan balance shrinks, the house gains value and the renter’s rent keeps rising: by year 10 it is $3,131 a month.

What moves the break-even year

Change one assumption at a time and the answer shifts a lot:

Change	Buying pulls ahead in
The example as above	Year 9
Prices rise 4% a year	Year 5
Prices rise 2% a year	Year 15
The same house would rent for $2,800	Year 5
The mortgage rate is 5.5%	Year 6
Invested money earns 4%	Year 7
Invested money earns 7%	Year 17

Two lessons. Price growth and the local rent level matter most, and you can check the second yourself today. And the case for renting depends on the renter actually investing the difference. Spend it and buying wins almost every time.

A quick screen: the price-to-rent ratio

Divide the price by a year of rent for a similar home: $420,000 ÷ ($2,400 × 12) = 14.6. As a rough rule, under about 15 leans toward buying, 15 to 20 is a close call, and over 20 leans toward renting. In expensive coastal cities, ratios above 25 are common, which is why renting there often wins for a decade or more.

What renting buys you

• Flexibility. A fixed-term lease runs a year, and a month-to-month tenancy can end with 30 days’ notice in most states.
• Your capital, free. The $96,600 stays invested, or on hand for a job change or an emergency.
• No repair surprises. The furnace is the landlord’s problem. Your exposure is the security deposit, which comes back if you leave the place in good shape.
• Room to negotiate. Rent is a price; see our guide on how to negotiate rent.

The trade-off is rent increases. At 5% a year, $2,400 becomes $3,063 in five years; the rent increase calculator shows any increase in dollars and percent. Some states cap increases and set notice periods; the rent increase notice by state table lists them.

What buying buys you

• A fixed payment. The $2,124 of principal and interest never changes on a fixed-rate loan. Tax and insurance can still rise.
• Forced savings. Every payment builds a little equity, and more each year.
• Control. Paint, pets and renovations are your call.
• Leverage. A 3% rise in a $420,000 house is $12,600 in a year, about 13% on the $96,600 you put in, before costs. The same leverage works in reverse when prices fall.

Mortgage interest is deductible only if you itemize, and most households take the standard deduction instead, so for many buyers the tax break is small or nothing.

Can you afford either?

For renting, the common guideline is rent at or under 30% of gross income: $2,400 a month needs about $8,000 a month, or $96,000 a year. Many landlords screen for income of three times the rent, $7,200 a month. The rent-to-income calculator runs both tests.

For buying, lenders often want the full housing payment at or below about 28% of gross income. At $3,034 a month, that points to about $10,800 a month before tax, plus the $96,600 up front and an emergency fund after closing.

Five questions that decide it

1. How long will you stay? Under five years, renting usually wins.
2. What is the price-to-rent ratio where you live?
3. Will you have three to six months of expenses left after the down payment?
4. Is your income steady enough for a fixed payment and surprise repairs?
5. If you rent, will you really invest the difference?

If you are torn, a rent-to-own agreement can lock a purchase price while you rent, but read it closely: the option fee is usually lost if you do not buy. At each lease renewal, run the numbers again. The answer changes as rates, prices and rents move.
