from my point of view it's a great place to live - we're in a cul de sac (semi-d) and have a little girl. it's very safe, all our neighbours are very friendly, a real sense of community, most of our neighbours are in early 30's like us, and we do tend to socialise alot with them - bbq's, parties, poker nights etc.
lots of young kids around so very friendly for families.
no properties rented at all so no problems there. there is quite a good management company and you should be able to see that all the public areas are well maintained.
we have had some water problems - every time the council cuts off water for repairs we are last area in swords to get pressure back as we're at the end of the line.
the estate is well laid out and build quality of houses are good. some gardens are quite small however so be careful there.
there is planning in for another 190 houses beside the estate but it's still going through the process.
don't know alot about the 2 houses for sale except that i thought 1 went sale agreed ages ago for 975k.
