Give Orford, Longford, Penketh, Sankey a miss. I grew up in Appleton/Stretton (mum and sister still live in a couple of detached houses just up from the Cat & Lion!), lovely area but doubt you would get anything there for your budget. Stockton Heath you might just about get a terrace as you get closer to Latchford, which is another choice. Lymm and Grappenhall are also nice areas but again, i think they are out of your price range.
