Moving to Belgium and maybe Brussels!

It's 70km from Brussels to Mol but it's a much longer drive than form Antwerpen, the most direct route is on minor roads, the quicker route is via south Antwerpen and that's 1 hour 20 minutes minimum. By train it's a minimum of 1 hour 30 minutes by train, via Lier which is south-east of Antwerpen.

Apartments are generally more expensive in Brussels than Antwerpen.

There are plenty of train stations in Brussels, 3 main ones are Midi/Zuid/South, Central and Nord/North.

There are 23 postcodes in Brussels region. South station is in 2 postcodes, depends on which exit you take, 1070 Anderlecht and 1060 St Gilles and is just across the road from Bruxelles Ville 1000. Central is in Bruxelles Ville 1000, North is in Schaerbeek 1030 but really near Bruxelles Ville 1000 and St Josse 1210.

There are lots of areas where it's not really advisable as a white foreigner to live, as you'll rather stand out. I'd avoid Anderlecht 1070, Molenbeek 1080, St Josse 1220, I'd be wary of certain areas in St Gilles 1060 and Schaerbeek 1030.

Personally, I would never live that far from work, you'll find a commute Brussels to Mol is something most Belgians would never consider. Eindhoven is only 47km from Mol, Tilburg is 48 km, Antwerpen is 53km. Or even plenty of lovely towns in the Mol area.  I would seriously consider Eindhoven or Tilburg - remember that Mol is actually on the border with the Netherlands.
