I rented in Horley and found my location blighted by APU/ engine noise, being upwind of the airport. Horsham is expanding rapidly, Wickhurst Green is very popular with crew. Also Kilnwood Vale, Horsham is nice but lacking in facilities at the moment..it's cheaper partly as a result of that and it's close proximity to Crawley. A new Horsham development of 2,500 new homes alongside the A264 has just been approved. So, overall I'd say Horsham is the place to settle.
