But keep in mind:
- North facing aspect: The property has a north-facing orientation, which may limit direct sunlight into the rear garden and principal living spaces during winter months.
- Management company fees: Buyers should verify if there are any annual management charges or service fees applicable to the common areas of the development.
- Terraced noise transfer: As a mid-terrace home, occupants should investigate sound insulation levels between adjoining properties to ensure adequate acoustic privacy.
- Air-to-water maintenance: The complex air-to-water heating system requires specialized servicing, so buyers should check the installation warranty and maintenance history records.
- Electric fire limitation: The living room features an electric fire rather than a traditional solid-fuel stove or open hearth, which may not suit all aesthetic preferences.
- Parking allocation rules: Residents should confirm whether parking spaces are designated to specific units or operate on a general unassigned permit system.
- EV charging infrastructure: Buyers needing electric vehicle charging should inspect whether the current parking setup allows for easy installation of a home charger.
- Garden size constraints: The walled-in back garden is relatively compact, potentially offering limited space for extensive landscaping or large family gatherings.
- Attic insulation standards: While the BER is strong, purchasers should verify the exact level of attic insulation and check for proper ventilation around roof spaces.
- Ventilation system filters: The Vent-axia air filtration system requires periodic filter replacements, representing a small ongoing maintenance cost for the homeowner.
- High demand traffic: The coastal road and access routes into Blackrock village can experience peak-time traffic congestion during fine weather and summer weekends.
- Property tax band: Buyers must check the correct local property tax valuation band applicable to this specific address to calculate ongoing yearly liabilities.
- Broadband provider choice: Although fibre is available, purchasers should verify which specific telecom operators currently service the network wiring in the square.
- Snagging on completion: As with any modern build, buyers should commission a thorough snagging inspection to identify any cosmetic or minor structural defects before closing.
- Future local development: Check local planning registers to ensure no large-scale construction projects are planned for surrounding vacant lands that might obstruct views.
- Home insurance premiums: Given the coastal proximity of the Blackrock area, buyers should obtain insurance quotes early to check for any special flood policy conditions.
- Utility connection tariffs: Verify the current suppliers for electricity and water to ensure efficient tariff choices are established upon moving into the property.
- Drainage and sewerage: Inspect the shared estate drainage systems to confirm responsibility for maintenance and to rule out any risk of surface water pooling.
- Window thermal efficiency: While double-glazed, buyers should inspect the seals around all windows and doors to ensure no draughts compromise the A3 rating.
- Title and boundary check: Legal advisors should carefully examine the title deeds and boundary maps to confirm exact ownership limits of the rear garden and parking.
Price positioning
?

- Potential factors supporting such a price include general property price inflation and high demand for energy-efficient homes, while broader economic headwinds or financing costs could undermine it.
