"Arrange" vs "Arrange for"

[Tom]

Hi

Could you please tell me the difference between:

1- He has to arrange a flat in the new city.
2- He has to arrange for a flat in the new city.

1- He has to arrange a flat in the new city.
2- He has to arrange for a flat in the new city.

Although 'arrange' can have several meanings, both your sentences suggest the same sense of 'organizing', especially as you've added 'in the new city'. To me they both mean: 'He has to find a flat in the new city'. The first sentence, however, could also mean that he already has a flat and has to adapt it, making some changes to it.
