I'm in Mossley, it's like anywhere, you've got good bits, bad bits, good pubs and not so good pubs… the riding is good, saddleworth area just round the corner, easy access to the peak, west yorks by bike. rossendale, hebden etc are only 30-45mins in the car.
Housing is 'cheaper' than some of the surrounding areas, especially saddleworth, I guess the main reason would be the larger proportion of smaller/terraced housing with Mossley's industrial history. There are larger houses about but apart from new builds and 80's/90's stuff they're not that common.
If you're looking and want a 'locals' opinion on house location drop me an email and I'll let you know. Or if you want a ride out and check out the scenery/pubs I could have my arm twisted too.
Cheers
Keith
