Me I live in Chester but if you can’t afford Chester then Mold and the villages surrounding like Cilcain and Pantymwyn are good with the benefit of having the Clwydians on your doorstep.
If the OP is having affordability problems, they’ll well out of their depth in Marford. :D
There’s plenty of cheap property in Chester too.
Personally I’d be looking towards Llandegla, but I have no need for the train. There’s an excellent bus service between Wrexham and Chester, so that would put Gresford on the map. I’d avoid Llay, Brymbo seems to have cleaned its act up a bit and doesn’t look too bad on the Minera Road side. If you’re looking at Hope, have a look at Higher Kinnerton.
I don’t know anything about Summerhill, there might be a reason why people don’t visit the place.
