23 knocknacree park

starting to look in the dalkey/killiney area and was wondering how much 23 knocknacree park is worth? i viewed it and it looks like its needs a total makeover any advice appreciated.

last one sold for under €600k that was about 6-8 months ago, this current one is smaller sq. footage and in worse shape, I dont think this will sell for more than 600k and I think its worth alot less, huge work to be done, replacing those north facing front windows would be a huge cost, lots of issues with it, really think this is a site you are buying but then again the estate is very sought after and close to the village and the views are the real selling point!

thanks for the advice
