Should I rent or buy in Dublin in 2026?
The honest maths.
Everyone has an opinion. Your parents say buy. Your friends say the market's about to crash. The internet gives you both hot takes and spreadsheets nobody reads. Here's what we actually did: ran the numbers on a realistic Dublin scenario, and told you what they mean.
The scenario we're modelling
To make this concrete, we're going to compare two people: Aoife buys a two-bed apartment in Dublin in 2026. Ciarán rents an equivalent place and invests the difference.
Here are the assumptions — deliberately realistic, not cherry-picked:
The Property
The Mortgage
💡 Why 3% property growth? Dublin property has averaged ~5–7% per year since 2012, but we're being conservative. Prices have cooled, supply is slowly improving, and projecting past performance forward is how people get burned.
The true cost of buying
Most people focus on the mortgage repayment. That's the wrong starting point. Before you make a single repayment, here's what leaves your account on day one:
| Cost | Amount | Notes |
|---|---|---|
| Deposit | €45,000 | 10% of purchase price |
| Stamp duty | €4,500 | 1% on first €1M |
| Solicitor fees | €2,500 | Typically €1,800–€3,500 |
| Surveyor / valuation | €700 | Structural survey + bank valuation |
| Land Registry & searches | €400 | Often bundled with solicitor |
| Moving costs | €800 | Removal company, storage |
| Total upfront cash needed | €53,900 |
That's €53,900 out the door before you've made a single mortgage payment. Now let's look at the monthly picture:
| Monthly Cost (Owner) | Amount |
|---|---|
| Mortgage repayment | €1,905 |
| Management fee (apartment) | €250 |
| Home insurance | €60 |
| Maintenance reserve (1% of value ÷ 12) | €375 |
| Property tax (LPT) | €30 |
| Total monthly cost | €2,620 |
⚠️ The maintenance reserve is real. Financial advisors recommend budgeting 1% of property value per year for repairs and maintenance. That's €4,500/year on a €450k property. Boilers break. Roofs leak. Kitchens age. Don't skip this line.
The true cost of renting
A comparable two-bed apartment in Dublin in 2026 rents for approximately €2,400–€2,600 per month. We'll use €2,450 as our baseline — a fair market rate for a well-located apartment outside the M50.
| Monthly Cost (Renter) | Amount |
|---|---|
| Rent | €2,450 |
| Contents insurance | €20 |
| Less: Rent Tax Credit (€1,000/yr) | −€83 |
| Total monthly cost | €2,387 |
So on a pure monthly basis, renting is €233 cheaper per month than owning in this scenario. But that's not the whole picture — and this is where most comparisons go wrong.
The deposit's hidden cost
Aoife spent €53,900 upfront to buy. Ciarán didn't — he kept renting and invested that €53,900 instead. This is called the opportunity cost of the deposit, and it's one of the most overlooked numbers in any rent vs buy comparison.
If Ciarán invests €53,900 into a diversified index fund at a conservative 7% annual return (the historical average of the global stock market):
| Year | Ciarán's investment pot | Aoife's equity in home |
|---|---|---|
| Year 1 | €57,673 | ~€8,600 equity built |
| Year 5 | €75,600 | ~€55,000 equity built |
| Year 10 | €106,000 | ~€140,000 equity built |
| Year 20 | €208,000 | ~€330,000 equity built |
| Year 30 | €409,000 | ~€605,000 equity built + owns property |
By year 10, Aoife is ahead in equity. By year 20, she's comfortably ahead. By year 30, she owns a property now worth ~€1.09 million and has €605,000 in equity — far ahead of Ciarán's investment pot.
But here's the crucial nuance: Ciarán also invested the monthly difference (€233/month) every month. Over 30 years, that extra €233/month at 7% is worth approximately €280,000 more. The gap closes — but Aoife's property ownership still typically wins over a 30-year horizon in Dublin.
When does buying actually win?
This is the right question. Buying has high upfront friction — the deposit, stamp duty, legal costs. The longer you stay, the more those costs are amortised across time. Here's the rough break-even:
| Time horizon | Winner | Why |
|---|---|---|
| Under 3 years | Renting | Transaction costs, early mortgage heavily interest-weighted |
| 3–7 years | It depends | Property growth pace and rate changes matter a lot here |
| 7–15 years | Buying edges ahead | Equity builds, rent keeps rising, you're protected |
| 15+ years | Buying wins clearly | Compounding equity, rent inflation, asset ownership |
The 7-year mark is roughly when buying tends to pay off in Dublin — assuming you're not forced to sell in a downturn and assuming rates don't spike dramatically beyond your stress test threshold.
What the maths doesn't capture
Against buying
- Illiquidity. Your deposit is locked in a depreciating-value asset if prices fall. Unlike an investment, you can't sell 10% of your house when you need cash.
- Rate risk. Fixed rates expire. If you fix at 3.9% for 5 years and rates hit 6% on renewal, your repayment jumps from €1,905 to €2,420/month. Can you absorb that?
- Life changes. Divorce, redundancy, relocation, a new relationship — owning makes all of these significantly more expensive and complicated. The average Irish person moves every 7–10 years.
- Concentration risk. Your entire net worth becomes one asset in one city in one country. Diversified investments don't have this problem.
Against renting
- Rent inflation. Dublin rents have risen an average of 5–8% per year over the past decade. In 10 years, your €2,450 rent could be €4,000+ at the same rate. Mortgage repayments are fixed.
- No security. Landlords can sell. Rent Pressure Zones help but they don't protect you from a Notice to Quit. Owners can't be evicted from their own home.
- Forced savings. Most people don't actually invest the difference. They spend it. Mortgage repayments are a forced savings mechanism. Without a mortgage forcing discipline, the numbers rarely work out as neatly as the model suggests.
- Pension in property. Owning your home outright in retirement means your housing cost effectively becomes €0 (bar maintenance). Renters in retirement need their pension to fund rent indefinitely.
The honest verdict
Neither is obviously right. Here's how to think about it.
BUY if…
- You plan to stay in the same city for 7+ years
- Your income is stable and you've stress-tested the repayments at 6%+
- You have the full deposit + at least €10k in additional savings as a buffer
- You value security and are not relying on capital growth to make the decision work
RENT if…
- Your life situation might change — relationship, career, location — in the next 3–5 years
- You don't have a meaningful buffer beyond the deposit and transaction costs
- You would stretch to the absolute limit of your borrowing capacity to buy
- You will genuinely invest the difference (not just say you will)
The question isn't "is buying better than renting?" It's "does buying make sense for my situation, at this price, at this stage of my life?" The maths is a framework, not a verdict.
Run your own numbers
The scenario above uses Dublin averages. Your property might be €320,000 or €600,000. Your deposit might be 20%, not 10%. Your investment return assumption might be different. None of that changes the framework — but it changes the output significantly.
