I work for in Salford Quays - Commute from Urmston by car is 15-20 mins by car in the morning, 30 mins in the evening. Other than Christmas (having to go past Trafford Centre) its very easy to get home to after school club pick up etc.
Urmston is a lovely area, we're so happy here. Unpretentious (as stated above), leafy, nice parks, a centre with Sainsburys/Aldi, Library, plus a few discount shops for bargains! A great area for families, it has everything from dance schools, brand new leisure centre, sports clubs, plus all general facilities.
Primary schools in the area are excellent. Trafford council is renowned for schooling, but Altrincham/Sale are much more expensive. Urmston is generally cheaper as it's not on the tram line, but not a problem if you're driving to Salford Quays. Trafford Park line has just opened (a 5-10 min drive away from Urmston), so park and ride again will be an option to Salford Quays. I won't be doing this, much quicker to drive straight there rather than waiting around for a tram.
There is generally very little dodgy housing/areas in Urmston, just the odd small estate here/there. If you look on Rightmove, 90% of anything in Urmston/Davyhulme/Flixton would all be great.
I work for a large organisation in Salford Quays, so know people who commute from all sorts of areas. Places like Glossop, Marple, Disley would be a nightmare as a single parent. Even places like Prestwich are a pain, I know people coming in by tram and changing at Cornbrook interchange; that part of the journey to the Quays takes ages. Fine without kids, not so much if you're chasing to get back to school.
If you're on your own, I'd really be looking at being able to drive easily. Other areas that are doable, and that I know parents commute from are Sale, Monton, Stretford, Chorlton.
Happy for you to DM me if you wanted more information. I've lived in the area 15 years (Trafford/Salford) so know it really well.
