Yes, if you only measure real estates. It is more affordable to buy house/flat ( very descent one) in RS/ B&H if you work as an ATCO. It is not unussual for some to have house with swimming pool, big garden, vineyard or orchard ( a few hundreds of plum trees, hazelnuts or so) , a few flats, new cars and so on...
Daily shopping ( groceries,clothes,technics ..
) is the same price ( if not higher) than NL. Quality and choice are much lower.
Last, but not least- general quality of life ( political stability , social security and general perspective....) are of course on side NL.
