But keep in mind:

  • Poor BER Rating: The property carries an inefficient F energy rating, indicating that extensive insulation, heating, and window upgrades are urgently required.
  • High Retrofitting Costs: Bringing this home up to modern energy standards will demand a substantial financial investment alongside the initial purchase price.
  • Outdated Interior Finishes: The internal decor requires complete modernisation across kitchens, bathrooms, and flooring to meet contemporary living expectations.
  • Potential Rewiring Needed: Given the mature nature of the house, buyers should budget for an electrical survey to check if the wiring requires replacement.
  • Plumbing System Overhaul: The existing heating and plumbing systems may be dated, requiring a full system upgrade or a new boiler installation.
  • Single Glazed Windows: Buyers should inspect the window joinery closely, as older properties of this vintage often feature glazing that needs replacement.
  • Potential Insulation Deficits: Wall and attic insulation levels are likely substandard based on the BER rating, impacting comfort and heating bills.
  • Renovation Disruption: Undertaking a comprehensive modernization project means the buyer may need to rent elsewhere or live through extensive building works.
  • Planning Permission Limits: Any major structural extensions to the rear or side will need to comply with local planning regulations and guidelines.
  • Asbestos Material Check: Older homes built during certain decades should be professionally checked for legacy materials such as asbestos in artex or tiles.
  • Ventilation Improvements: Modernizing an older home with improved airtightness will require careful planning for proper mechanical or passive ventilation.
  • Bathroom Modernization: With only two bathrooms serving a five-bedroom home, additional sanitary facilities or extensions will likely be required.
  • Drainage Survey Requirement: A thorough CCTV drain survey is recommended to ensure the older underground drainage network is free from root ingress or damage.
  • Roof Structure Inspection: The roof timbers and coverings should be professionally assessed to ensure there are no hidden leaks or structural sagging.
  • Boundary Verification: Buyers must verify exact property boundaries and title maps with their legal representative to prevent any future boundary disputes.
  • Local Traffic Congestion: Access routes in and out of the wider area can experience peak-hour commuter congestion during school and working terms.
  • Upfront Capital Requirements: Beyond the asking price, the buyer must hold significant cash reserves to fund the necessary energy and cosmetic upgrades.
  • Uncertainty of Hidden Defects: Opening up walls and floors during renovations often reveals unforeseen structural or damp issues requiring extra funds.
  • Extension Restrictions: The orientation and layout of neighboring properties might limit the scale and positioning of any future ground-floor extensions.
  • Compliance Certification: Buyers must ensure all previous historical alterations or extensions have proper planning compliance and building regulation certificates.

Price positioning

?
This comparison depends on limited public and listing evidence, which may be incomplete, outdated or not directly comparable. The score is not a percentage, professional valuation or guaranteed estimate. Ask an independent qualified valuer before relying on a property value.
The asking price looks somewhat undervalued compared with the available evidence.
  • The asking price of €750,000 appears slightly undervalued relative to the immediate estate context, primarily because comparable houses on the same road have achieved higher figures in recent transactions despite potential modernization needs.
  • Valuation signals present a mixed outlook, where the generous 159 square meter floor area and quiet cul-de-sac location argue for a higher worth, balanced against a poor BER rating that requires substantial capital investment.
  • A supportive factor for this price point is the enduring high demand for family homes in well-established Dublin 16 locations, whereas the very weak energy rating could actively undermine buyer enthusiasm without immediate financial concessions.
  • Additional relevant factors include the substantial opportunity for new owners to reconfigure and add value through extensive renovations, making the lower initial asking price an attractive entry point for purchasers willing to undertake upgrades.

Build Analysis

What we know from similar construction types

  • The property is a semi-detached family home built in a mature residential development, offering a generous floor area of 159 square meters on a quiet cul-de-sac.
  • The description notes significant potential for reconfiguration, modernization, and further enhancement, indicating that the building may require substantial interior updating to meet modern standards.
  • A buyer should investigate the structural integrity, electrical wiring, plumbing systems, and insulation levels, as the current layout and finishes appear to date from an earlier construction era.
  • Given the mature setting and the presence of established trees and planting near the property, a buyer should check for potential root interference with drains and foundations.

Retrofit Cost*

Possible renovating / insulating expenditure

  • The property has a poor BER rating of F, which indicates that the building envelope, heating systems, and thermal insulation fall well below current energy efficiency standards.
  • A deep retrofit to bring this 159 square meter home up to a modern BER rating (such as B2 or A) would likely cost between EUR 65,000 and EUR 95,000.
  • Major works required would typically include external wall insulation, upgrading windows and external doors, installing a modern heat pump or high-efficiency heating system, and adding attic insulation.

Heating cost*

Estimated expense to heat this property every year

  • Estimated annual heating cost: approximately 2500 to 3500 euro.
  • Explanation: Given the floor area of 159 square meters and a poor BER rating of F, the property is likely to have high thermal heat loss, resulting in significantly above-average heating demands.

Pollution Safe

Environmental situation to investigate

8/10

Water overflow reports to follow up
