Dublin City Delivers 8.4% Gross Yield, No Short-Term Rental Needed

Estimates for a typical 3-bedroom house. Short-term letting is not available to investors in this market.

At 8.4% gross, Dublin City sits comfortably above both the Eastern and Midland regional average (8.1%) and the national average (7.5%). The question is not whether short-term letting beats long-term letting (it cannot, legally), but whether the long-term yield justifies entry at Dublin's price point.

Dublin City's RPZ Rules Mean Long-Term Letting Is the Only Legal Path for Investors

Ireland became a nationwide Rent Pressure Zone in June 2025, and Dublin City sits squarely within it. For investors, the regulatory picture is unambiguous: you cannot legally operate a short-term let on a property you do not live in. Only owner-occupiers may let their principal private residence for up to 90 nights per year without planning permission.

From 20 May 2026, all hosts must also register on the Fáilte Ireland Short-Term Letting Register. Registration is free initially, with annual renewal and a compliance declaration required. Platforms like Airbnb must display registration numbers on all listings.

For buy-to-let investors, this means the entire strategy discussion reduces to one question: does long-term letting in Dublin City generate adequate returns? With gross yields averaging 8.4%, the headline answer is yes, though costs and tax erode that figure significantly.

The RPZ also caps annual rent increases at 2% (or the Harmonised Index of Consumer Prices, whichever is lower). This limits income growth but provides stability: vacancy risk in Dublin City remains low given persistent housing demand. Investors should model income growth conservatively at 2% per year rather than assuming market-rate increases.

Top Suburbs Yield Over 11%, but Entry Prices Vary by €230,000

Dublin City contains 163 electoral divisions, and gross yields range from under 7% in premium southside areas to over 11% in the north and west. The price spread is equally dramatic: the cheapest 3-bed houses sit around €334,275, while the most expensive reach €564,592.

The pattern is clear: lower entry prices drive higher yields. Areas like Decies, Finglas North C, and Ballymun B all sit below €456,630 while commanding similar rents to more expensive suburbs. Rathfarnham and Botanic B, by contrast, carry price tags above €500,000 with comparable rental income, compressing their yields.

These are averages per suburb. The dashboard breaks it down further, by bedroom count and property type, so you can model your specific property.

Operating Costs Take Roughly a Quarter Off Dublin City's Gross Rent

A 8.4% gross yield does not translate to 8.4% in your pocket. Long-term letting in Dublin City carries several recurring costs that investors must account for.

Management fees typically run at around 8% of collected rent if you use a letting agent, which on €3,211 per month equates to roughly €3,080 per year. Landlord insurance costs approximately €848 annually. Maintenance and repairs average around €4,749 per year for a 3-bed house (covering routine upkeep, not major capital works). Local Property Tax (LPT) adds €414 at the current rate of 0.1% of market value.

Totalling these: management (approximately €3,080), insurance (€848), maintenance (€4,800), and LPT (€414) come to roughly €9,090 per year. Against annual gross rent of €38,531, that leaves approximately €29,440 before tax and mortgage costs. Stamp duty on purchase applies separately; check current banded rates with your solicitor, as these change periodically.

Investors who self-manage can save the management fee, pushing net operating income closer to €32,500. For a city with strong tenant demand and low vacancy rates, self-management is feasible, though the RPZ's strict compliance requirements (rent reviews, notice periods, RTB registration) demand careful attention to detail.

After Tax, Dublin City Investors Keep Roughly Half of Net Rental Income

Ireland's tax treatment of rental income is among the least favourable in Europe for individual landlords. Rental income is taxed at your marginal rate: 20% at the standard rate, rising to 40% on the higher band, plus Universal Social Charge (up to 8%) and PRSI (4%). The effective top rate reaches approximately 52% on rental income.

On estimated net operating income of around €29,440 (after operating costs but before mortgage interest), a higher-rate taxpayer would owe roughly €15,300 in income tax, USC, and PRSI. That leaves approximately €14,140 after tax, before any mortgage payments.

There is one significant offset: 100% of mortgage interest is deductible against rental income for residential lettings. For an investor financing 70% of €456,630 at current rates, mortgage interest could reduce the taxable amount substantially. At a 4% interest rate on a €320,000 loan, annual interest of roughly €12,800 would cut the tax bill by approximately €6,650 for a higher-rate taxpayer.

Pre-letting expenses are deductible up to €10,000 for properties that have been vacant for more than 12 months, which can help offset initial refurbishment costs. Capital gains tax on disposal is 33%. The RPZ rent cap of 2% per year limits income growth, meaning investors should model tax obligations conservatively rather than assuming significant rental increases over time.

Dublin City Yields Outperform the Regional and National Average

Comparison of key investment metrics.

Dublin City's higher sale prices (around €456,630 vs the national average of €287,540) are more than offset by significantly higher rents. The result is a gross yield that exceeds both the regional and national benchmarks. This is notable because Dublin is often perceived as "too expensive" for rental investment; the data shows that rents have kept pace with, and in many suburbs outpaced, price growth.

The entire country operates under the same RPZ rules, so there is no regulatory advantage to investing outside Dublin. Every Irish market faces the same 2% rent cap and the same prohibition on investor short-term letting. The decision between Dublin and other markets comes down to yield, tenant demand, and entry price, not regulation. See our data sources for how we calculate these averages.

Dublin City's Cash Flow Covers the Mortgage, but Only Just

Cash flow positive from day one is achievable in Dublin City, but the margin depends heavily on leverage and suburb selection. Consider a typical scenario: a 3-bed house purchased at €456,630 with a 70% loan-to-value mortgage (approximately €320,000 borrowed) at a 4% interest rate over 25 years.

Monthly mortgage repayments would be roughly €1,690. Against monthly rent of €3,211, that leaves approximately €1,520 per month before operating costs and tax. After deducting management fees (around €257/month), insurance, maintenance, and LPT, the monthly cash surplus narrows to roughly €760 before tax.

At the top suburbs like Decies and Finglas North C, where entry prices sit around €335,000 to €375,000, the mathematics improve considerably. Lower purchase prices mean smaller mortgages, while rents remain comparable. An investor buying at €334,275 with 70% LTV would borrow roughly €234,000, reducing mortgage repayments to approximately €1,235 per month and widening the pre-tax cash surplus.

High-leverage investors (80%+ LTV) face tighter margins. At 80% LTV on €456,630, monthly repayments rise to approximately €1,930, leaving just €1,280 before all costs. In pricier suburbs like Rathfarnham, this approach risks negative cash flow after tax.

Investment Bottom Line for Dublin City

Dublin City offers a clear proposition for long-term letting investors: strong gross yields averaging 8.4%, persistent tenant demand driven by population growth and housing undersupply, and top suburbs exceeding 11% gross. The trade-offs are equally clear: high entry prices (averaging €456,630), a punitive tax regime that can claim over half of net income, and RPZ rent caps that limit income growth to 2% per year.

Short-term letting is not an option for investors under Ireland's nationwide RPZ. This simplifies the decision but removes a potential income lever. Investors who need the flexibility to pivot between strategies should look at markets outside Ireland entirely.

For those committed to Irish property, Dublin City's combination of yield and demand is difficult to match elsewhere in the country. The key is suburb selection: a difference of €230,000 in purchase price between areas with similar rents creates a yield gap of 3 to 5 percentage points.
