Estimates for a typical 3-bedroom house. Short-term letting is not available to investors in this market.
Rents in Dún Laoghaire-Rathdown are substantially higher than both the regional and national medians, reflecting the area's strong tenant demand. However, purchase prices are proportionally even higher, which compresses the gross yield below the 7.4% regional average and the 6.7% national average.
This is the classic premium market trade-off. Investors pay more to enter a market with lower vacancy risk, stronger tenant quality, and historically robust capital appreciation. The yield is lower, but the asset tends to hold value through downturns better than higher-yielding markets in less sought-after locations.
For investors prioritising cash flow, markets outside the Dublin commuter belt will typically offer better gross yields. For those prioritising capital preservation and long-term appreciation in a supply-constrained area, Dún Laoghaire-Rathdown's premium pricing reflects genuine underlying demand.

Investment Bottom Line: Appreciation Play With Steady Rental Income
Dún Laoghaire-Rathdown is a long-term letting market by law and by economics. The ban on investor short-term letting is absolute, and even if it were not, the numbers would not support it: the 90-night cap and operating costs would push short-term letting returns deeply negative. Long-term letting is the only viable strategy.
Within that strategy, the county offers a gross yield of 5.7% and a net yield of approximately 3.6% after operating costs. After income tax at the top marginal rate of approximately 52%, the real cash return narrows further. This is not a cash flow market. It is an appreciation market with rental income that covers costs and provides a modest return.
The variation between electoral divisions matters. Choosing Stillorgan-Leopardstown over a premium coastal area could mean the difference between a yield of 6.9% and something meaningfully lower. With 69 electoral divisions in the county, the dashboard is the best way to model your specific target area, bedroom count, and property type.
| Investor Type | Fit |
|---|---|
| Cash Flow Focused | Fair |
| Appreciation Focused | Excellent |
| Short-Term Rental Operator | Not Viable |
| High Leverage (80%+ LTV) | Good |
High leverage investors benefit from the 100% mortgage interest deduction, which reduces the tax burden and improves cash-on-cash returns. The strong rental demand in Dún Laoghaire-Rathdown also reduces the risk of extended vacancy periods that can be devastating for leveraged positions.
