For many people in Ireland, the decision to buy a home or continue renting is about much more than finding somewhere to live.
It is also one of the biggest financial decisions a household will make.
Buying can mean years of mortgage repayments, but it also creates an asset that may increase in value. Renting avoids the costs and responsibilities of homeownership, while potentially allowing a household to invest money that would otherwise be tied up in a deposit and property.
So which approach could leave someone financially better off over the long term?
There is no universal answer.
The result depends on the property price, rent, mortgage rate, deposit, house-price growth, investment returns and the costs associated with owning a home.
For M10news, we looked at the latest Irish housing, rental and mortgage data to examine how the two choices compare.
Ireland’s housing market has changed the calculation
The median price paid for a residential property in Ireland was €399,999 in the 12 months to July 2026, according to the Central Statistics Office.
National residential property prices were 5.5% higher than a year earlier. Dublin prices increased by 4.4%, while prices outside Dublin rose by 6.4%.
The median price in Dublin was €500,000, compared with €399,999 nationally.
That means a typical buyer is facing a substantial upfront cost before even considering mortgage interest, insurance, maintenance and other expenses.
For a first-time buyer, the Central Bank’s mortgage rules generally require a minimum 10% deposit.
On a €400,000 property, that would mean a €40,000 deposit before other purchasing costs are taken into account.
Renting is expensive too
The alternative is not cost-free.
The latest RTB/ESRI Rent Index shows that the standardised average rent for a new tenancy reached €1,839 a month nationally in the first quarter of 2026.
That was 9.1% higher than a year earlier.
Existing tenants were paying an average of €1,513 per month, highlighting the difference between the cost faced by someone entering a new tenancy and someone who has remained in an existing rental.
The figures show why the buying-versus-renting calculation can be very different for an existing tenant compared with someone entering the rental market today.
What would a €400,000 home cost to finance?
Consider a simplified example.
A buyer purchasing a €400,000 home with a 10% deposit would borrow €360,000.
The Central Bank reported a weighted average interest rate of 3.48% on new Irish mortgage agreements at the end of July 2026.
At that rate, a €360,000 mortgage over 25 years would have a monthly repayment of approximately €1,798.
That figure is only the mortgage repayment.
A homeowner also has to consider insurance, Local Property Tax, maintenance and other costs.
The actual rate available to an individual borrower can also be higher or lower than the national average.
The homeowner’s advantage: building equity
One of the biggest differences between renting and buying is what happens to the money being paid each month.
A rent payment provides housing for that month.
A mortgage payment does two things: part pays interest to the lender and part reduces the outstanding loan balance.
By the end of a 25-year mortgage, assuming the mortgage has been fully repaid, the homeowner owns the property outright.
The value of that property will depend on what happens to the Irish housing market during those 25 years.
For illustration, if a €400,000 property increased in value by an average of 3% a year for 25 years, it would be worth approximately €838,000.
That is an illustration rather than a forecast. House prices do not rise at a fixed rate every year, and past performance cannot guarantee future returns.
But homeowners face costs that renters do not
The mortgage is only one part of the cost of owning a property.
A homeowner also needs to allow for:
- Mortgage interest
- Home insurance
- Local Property Tax
- Maintenance and repairs
- Management fees for some apartments
- Legal and purchasing costs
- Stamp duty
- Estate-agent and other selling costs when the property is eventually sold
These costs can materially change the comparison.
For example, an owner who spends thousands of euro replacing a roof, repairing a heating system or carrying out major maintenance cannot simply compare their mortgage payment with the rent paid by a tenant.
The renter has an opportunity too
Renting does not necessarily mean that all of the renter’s money disappears.
The financial question is what happens to money that the renter does not have to put into a property.
The most obvious example is the deposit.
A person buying a €400,000 home with a 10% deposit would need €40,000.
A renter could potentially invest that €40,000 instead.
The renter could also invest any difference between their total monthly housing costs and the homeowner’s costs.
If those investments generate returns over many years, compound growth can become significant.
But investment returns are not guaranteed.
Shares and other investments can fall in value, sometimes substantially, and a person choosing this strategy would have to accept investment risk.
The biggest variable may be time
The longer someone stays in a property, the more important the long-term calculation becomes.
Buying a home involves substantial upfront costs.
A buyer who purchases a property and sells it after only a few years may have less time to benefit from property appreciation and mortgage principal repayment.
Someone who remains in the property for 20 or 25 years has a very different financial position.
The same applies to renting.
A long-term renter who consistently invests their savings and the difference between renting and owning could accumulate substantial financial assets.
But that depends on actually making those investments.
If the money that would have been invested is instead spent on other goods and services, the theoretical advantage disappears.
A 25-year way of looking at the decision
A useful comparison should track two households over the same period.
Household A: The buyer
The buyer:
- Purchases a property
- Provides a deposit
- Takes out a mortgage
- Repays the mortgage over 25 years
- Pays ownership costs
- Benefits from any increase in property value
- Owns the property outright if the mortgage is fully repaid
Household B: The renter
The renter:
- Does not use the deposit to purchase a property
- Pays rent
- Invests the deposit instead
- Invests any potential monthly savings where affordable
- Receives investment returns, but also takes investment risk
- Does not own a property at the end of the period
Illustrative 25-year comparison
The diagram below shows one modelled scenario comparing buyer equity with the wealth accumulated by a renter who invests.
Illustration: Buyer equity and renter investment wealth over 25 years under the assumptions shown in the model.
In this particular illustration, the starting property price is €340,000, annual house-price growth is 3% and the mortgage interest rate is 3.48%.
After 25 years, the model shows:
- Home value: approximately €837,511
- Buyer equity: approximately €711,884
- Renter invested wealth: approximately €145,924
These figures are illustrative rather than a forecast. They depend on the assumptions used by the model, and changing the property price, mortgage rate, house-price growth, rent, investment return or other variables can produce a different result.
The diagram should therefore be viewed as an example of how the comparison works, rather than proof that buying will always outperform renting.
What happens if house prices grow slowly?
This is where the comparison becomes more complicated.
Suppose the €400,000 home grows by only 2% annually for 25 years.
It would be worth approximately €656,000 at the end of the period.
At 3% annual growth, it would be worth approximately €838,000.
At 4% annual growth, the value would rise to approximately €1.07 million.
Those three outcomes are dramatically different.
The homeowner’s final wealth therefore depends heavily on what happens to property values.
The renter faces a similar uncertainty with investment returns.
Rent growth matters too
Rent is not necessarily fixed for 25 years either.
Ireland introduced national rent-setting rules in March 2026, with rent increases generally limited to 2% or inflation, whichever is lower, subject to the rules applying to the tenancy.
However, rents for new tenancies can behave differently from rents paid by existing tenants.
The Q1 2026 RTB/ESRI data showed new-tenancy rents rising much faster than existing-tenancy rents.
That distinction matters when modelling the future cost of renting.
Someone who remains in the same tenancy may experience a very different rental-cost path from someone who moves repeatedly and enters new tenancies.
Buying versus renting is therefore not simply a monthly-payment calculation
Looking only at a mortgage payment and rent would give an incomplete picture.
The homeowner has additional ownership costs.
The renter has no property asset at the end of the rental period unless they have invested elsewhere.
The homeowner builds equity.
The renter keeps their capital more flexible.
The homeowner takes property-market risk.
The renter takes investment and future-rent risk.
Neither option is financially risk-free.
What the Irish data tells us now
Ireland’s current housing market makes the decision particularly important.
Property prices are still rising, with the national index increasing 5.5% in the year to July 2026.
At the same time, new-tenancy rents were rising by 9.1% annually in the first quarter of the year.
Mortgage rates have also become a major part of the affordability equation, with the average rate on new mortgage agreements at 3.48% in July.
This creates pressure on both sides of the housing market.
Buying requires a large upfront commitment and exposes households to mortgage and property costs.
Renting avoids those ownership costs but leaves households exposed to rental prices and the need to build wealth through other means.
So, is buying better than renting?
There is no single answer for every household.
Buying can become financially attractive when a person stays in the property for a long period, house prices grow over time and the mortgage is gradually paid down.
Renting can be financially competitive when property prices are very high relative to rents, when a household can invest its deposit and savings successfully, or when buying costs would otherwise be substantial.
The answer also depends on circumstances that cannot easily be captured in a spreadsheet.
A homeowner may value security and control over their home.
A renter may value flexibility and the ability to move without selling a property.
For that reason, the financial calculation should be treated as one part of the decision rather than a definitive answer.
The M10news 25-year test
The most useful way to compare the two options is not to ask whether buying or renting is universally better.
Instead, the question is:
Under what conditions does buying come out ahead, and under what conditions does renting and investing come out ahead?
Using Irish property prices, rents and mortgage costs, different assumptions for house-price growth, rent growth and investment returns can produce very different results.
The figures should therefore be viewed as scenarios rather than predictions.
For anyone making a real decision about buying a home, the most important step is to test the calculation using their own property price, deposit, mortgage rate, rent and expected time in the home.
The bottom line
The Irish housing debate is often reduced to one question: “Is it cheaper to buy or rent?”
The better question is:
“Which option leaves me with greater financial wealth after all the costs and returns are taken into account?”
That requires looking beyond the monthly mortgage payment or rent.
It means considering the deposit, mortgage interest, maintenance, taxes, insurance, rent increases, house-price growth, investment returns and the length of time the household expects to stay in the property.
And in Ireland’s current housing market, those variables can make the difference between buying and renting being financially advantageous.
