What the sales say
The kind of place Castleknock Dublin 15 is
Read out of the sales themselves. None of this is a description of what Castleknock Dublin 15 is like to live in, which we have no way of knowing. It is what changed hands here.
Established housing
Almost nothing sold here since 2016 was new: 1% of sales. What changes hands is what is already there.
In line with Dublin
The median here sat within a quarter of the county median in 2025, so it tracks the county rather than standing apart from it.
A steady market
58 sales counted in 2025. Enough changes hands for the figures to hold up.

How the place was worked out
The register has no town column. It has an address, and the place is read out of it: the county is stripped off and the part left at the end is the locality. Addresses that end in a street name rather than a place are not counted towards anywhere.
A place appears here only where at least forty sales were recorded in it, and a figure is printed for a year only where at least ten sales sat behind it.
