How we estimate

We take recent sold prices from the Property Price Register, adjust each to today's money with the CSO price index, and weight them by how close and how recent they are. We blend that with a model trained on 5,000 matched sales that knows how price moves with floor area, bedrooms, BER, type and area, and we correct for condition read. Our estimate is the blend; the range is where 80% of homes like this actually sold.

Tested on sales the model had never seen: half land within 8% of the sale price, four in five within 20%. It never sees the survey. An estimate, not a valuation.

This property is a contemporary, modern residential dwelling situated on a corner plot within a recent development off Phoenix Park Avenue. It features robust red-brick construction, modern pitched roof detailing, and large architectural feature glazing, combining modern aesthetics with solid modern building standards.

4 large multi-unit applications on the register within 1 km. These are applications matching multi-unit residential wording anywhere in the planning record for this area, which goes back decades.

10 must-do checks, tailored to this house. Budget €3.3k to €6.8k for the paid ones.

Get your surveyor to

Commission a pre-purchase survey from a chartered building surveyor
The most important spend before you sign, and the only thing that examines the actual fabric of the building. Nothing in an online report replaces it.
MUST
€500 to €1.1k

Get your solicitor to

Instruct a solicitor for title, planning and local authority searches
Confirms the seller owns what they are selling and that everything built has permission.
MUST
€2.2k to €4.5k
Get Certificates of Compliance with planning and Building Regulations for any extension or attic conversion
Unauthorised work can block your mortgage and becomes your problem the day you close.
MUST
Check the Local Property Tax band is correctly declared and paid up
An under-declared band follows the property to you, not the seller.
MUST
Review the nearby planning applications in full
What gets built next door affects both how you live there and what you sell it for.
MUST

Ask the seller or agent

Ask for the BER certificate and the advisory report that goes with it
The advisory report lists the specific upgrades recommended for this house.
MUST
Ask why they are selling and how long they have owned it
Free, and it tells you more about the property and your negotiating room than any document.
MUST

Do this on your viewing

View a second time at a different time of day
Traffic, noise, parking and light all change. Most buyers only ever see a house once.
MUST

Sort with your lender or broker

Confirm your approval covers this specific property and price
Approval in principle is not a loan offer. The lender still has to value and approve this house.
MUST
€150 to €200
Budget for stamp duty and check what other costs land at closing
Stamp duty is 1% up to €1m, 2% between €1m and €1.5m, and 6% above that.
MUST
8 more worth doing
Confirm the boundaries on the title map match what you were shown
Boundary disputes are slow, expensive and surprisingly common.
SHOULD
Check the BER certificate has not expired
A BER lasts ten years. An expired cert will not support a green mortgage rate application.
SHOULD
Look for Japanese knotweed in the garden and along boundaries
It is a genuine mortgage blocker in Ireland, and treatment runs for several years.
SHOULD
Ask whether the property has ever flooded, and about any insurance refusals
A seller need not volunteer problems, but must not misrepresent when asked. So ask, in writing, through your solicitor.
SHOULD
Run every tap, flush every toilet, open every window
Water pressure, drainage and rotten frames are expensive and easy to miss in a ten-minute viewing.
SHOULD
Get into the attic and look under the stairs
Insulation depth, damp and the age of the wiring are all visible where nobody looks.
SHOULD
Ask whether the ground floor has been tested for pyrite (IS 398)
Relevant for homes built in the Leinster region during the 2000s boom.
SHOULD
€400 to €900
Do a radon test if you buy, or ask if one has been done
Ireland is a European radon hotspot. Testing is cheap and remediation is usually straightforward.
WORTH IT
€30 to €50
