Hi! My family and I are planning a move to Manchester next summer and are fairly decided that we would like to settle in Trafford, as we have a child who will be attending their first year at sixth form next September. She would like to attend either Sale, Urmston or maybe Stretford grammar school for sixth form.
When we move, we will initially rent a 2/3 bedroom house with a budget of £850. Is this a reasonable budget? We already know that Altrincham, Hale, Bowdon etc. are not realistic for us, but I hope you can advise me on some other areas! 
We are just looking for a safe area with good connections into Manchester, preferably on the metro link.
We really liked the Firswood area and it seemed within our budget but I've received mixed feedback on it. Does anyone know anything about how safe/pleasant to live it is there?
Thank you for your help!
