Dublin's Salary Map: Exactly What You Need to Earn to Buy in Every Postcode

Executive Summary

Analysis of 15,710 Dublin property transactions (2024–2025) reveals stark income barriers across the city. A single buyer needs a minimum salary of €73,125 to enter the cheapest postcode with a 2-bed apartment (D22), rising to €219,375 to access a 3-bed house in D4 or D6. Only 5% of Dublin's market is accessible to a single buyer earning €60,000 — the approximate average Dublin salary. This data maps the precise income required to meet Central Bank lending rules at every Dublin postcode, by property type and bedroom count.

How Irish Mortgage Lending Works: The Central Bank Rules

The Central Bank of Ireland imposes two binding constraints on mortgage borrowers:

1. Loan-to-Value (LTV): First-time buyers can borrow up to 90% of the purchase price (10% deposit required)
2. Loan-to-Income (LTI): Maximum mortgage = 4x gross annual income

These rules create a straightforward formula:

Salary required = (Property price × 0.9) ÷ 4

For a couple, lenders typically assess combined income:

Combined income required = (Property price × 0.9) ÷ 4 Each partner's share = (Property price × 0.9) ÷ 8

A €400,000 property therefore requires:

• Single buyer: €90,000 salary (€360,000 mortgage + €40,000 deposit)
• Couple: €45,000 each (combined €90,000)

What Your Salary Actually Buys

Single Buyer

Couple (Combined Income)

The single-buyer reality: On the average Dublin salary of ~€52,000, the maximum mortgage is €208,000 — enough to buy approximately 2% of the market, almost exclusively 1-bed apartments in the cheapest postcodes.

Entry Points by Property Type

2-Bedroom Apartments — Lowest Salary Required

The most accessible route into the market:

D22 is the outlier: A salary of €58,725 buys a median 2-bed apartment. This is the lowest entry point for a 2-bed unit anywhere in Dublin by a significant margin.

3-Bedroom Houses — The Family Home Threshold

A 3-bed family home in Dublin 4 or Dublin 6 requires a single-buyer salary over €200,000 — well above the top 5% of Irish earners. For couples, it remains at €104,000 each.

---

The Apartment vs House Premium

The price gap between apartments and houses varies significantly across Dublin:

In D6 and D18, a house costs more than double the equivalent apartment. For buyers priced out of houses in premium postcodes, apartments offer a viable entry point at roughly half the price.

Strategic Implications

For Buyers: Choosing Your Postcode by Budget

Under €70k salary (single) or €35k each (couple): Market access is extremely limited. Target 1-bed apartments in D22, D24, D11, or D17. These four postcodes represent almost the entire accessible market on a single average-to-above-average salary.

€70k–€90k salary (single): The 2-bed apartment market opens up across D22, D24, D11, D17, D12, D15, and D9. This is the most efficient income bracket — €80k unlocks 21.7% of the total Dublin market. Beyond 3-beds, expect to consider D10, D17, or D22.

€90k–€120k salary (single): Full 2-bed apartment access citywide including D3, D8, and D7. Three-bed houses accessible in D10, D17, D22, D11. At €100k, over 42% of the market is within range.

Couple, €60k each: Roughly 60% of the Dublin market is accessible. Three-bed houses are achievable in 10+ postcodes including D24, D15, D11, D22. This is where family formation becomes financially viable.

Couple, €80k each: 80% market access. Four-beds open in D24, D15, D11. Three-beds in D7, D8, D3, D9, D5, D12, D13. Only D4, D6, D14, D16, D18, D6W remain largely out of reach.

For Sellers: Pricing to Maximise Buyer Pool

Every €50,000 added to asking price increases the required single-buyer salary by approximately €11,250. In competitive postcodes like D10 (92.5% over asking) and D11 (89.7% over asking), sellers have pricing power — but in areas like D1 (67.5% over asking) and D18 (77.6% over asking), the buyer pool thins at elevated price points.

For Investors: Apartment Yields in Accessible Postcodes

The cheapest postcodes for entry (D22, D17, D24) also offer strong rental demand due to their affordability. Apartments in D22 at a median €261,000 represent the lowest capital outlay in Dublin for a 2-bed rental unit. With Dublin rent averaging €2,200+/month for a 2-bed (RTB Q3 2025 data), the indicative gross yield at that entry price is approximately 10.1% — the highest accessible yield bracket in the dataset.

Conclusion

Dublin's property market has a stark income geography. The city splits roughly into three zones:

• Affordable entry (D10, D17, D22, D24, D11): Single buyers on €70k–€90k can access 2-bed apartments; couples on €60k each can reach 3-bed houses
• Mid-range (D15, D12, D9, D8, D7, D5, D13): Requires €90k–€120k single or couples earning €55k+ each; 3-bed houses at or above €440k
• Premium (D3, D4, D6, D6W, D14, D16, D18): Family houses require €140k+ single or €70k+ each for a couple; the apartment premium is lower but still demands €80k+ salary

For first-time buyers, the practical entry point is a 2-bed apartment in D22 or D24 on a salary of €60k–€65k — but only with a 10% deposit already saved. Couples jointly earning €120,000 unlock the majority of the market, including 3-bed family homes across the affordable southern and northern suburbs.

According to the Central Statistics Office, median gross earnings in Dublin stood at approximately €47,000–€52,000 per worker in 2024, meaning most single earners are priced out of all but the cheapest corner of the Dublin market (CSO Earnings and Labour Costs, Q4 2024.
