Zion, Beach Park and Wadsworth are all vying for the same buyer and each community has it's advanvtages. All are remote suburban to chicago and that makes them tough to sell to someone that works in chicago. Not having signs in the yard might mean that the owners are delinquent and waiting to have bank foreclose on them. There are a lot of newer construction homes and some older homes on acre lots to consider depending on if you want land or square footage, newer construction tract house or charming older home.
I am an active Lake County agent, based in Lake county that used to live in Wadsworth, has family in Gurnee and works out of Libertyville. Contact me directly if you would like me to help you sort through your options.
