Thank you so much to everyone who gave advice on my last thread, it's been an amazing help. We visited for a week, back yesterday, and I've more questions if you don't mind helping..
So, we had a tour with a relocation agent and saw all the areas we asked about: Oak Park (thinking this would be a comparison for N Shore), Evanston and a few places on the North Shore (bits of Wilmette, Highland Park, Lake Forest).
We ended up waiting 90 mins for a delayed train at Lake Forest which may have unfairly biased against the area but have essentially decided it's too far out (husband will be commuting to the Loop every day). I think we had some dream of stretches of beaches and lakeshore accessibility on the North Shore and have realised that is not the case. So: although it will ultimately depend on what houses are available close to a decent elementary school when we arrive we have loosely decided on Oak Park, Evanston, south North Shore.
Here is my question (sorry for epic post) - how safe is Oak Park? I feel ok about Evanston and North Shore but liked OP and we are concerned about availability of rental houses in Ev and NS after hearing horror stories from realtors. But, for every 3 online love ins for Oak Park there is a warning about safety regarding surrounding areas. Any experience or anecdotal evidence of how safe it is - particularly the commute into downtown - would be incredibly helpful.
Please chuck any advice you have at me anyway - offer letter will be signed next week to move in early Jan and then there's no going back (visa issue permitting) so I will be haunting this board regularly.
