I google-searched for "relocate northwest" and came up with zero examples in the meaning implied here. Don't you think we ought to say "relocate to the Northwest of Huston, relocate to northwest Huston, relocate to somewhere in the Northwest of Huston, etc."?
Yes, I am looking to relocate northwest of Houston.
The above sentence seems to mean that I am actually move "northwest of Huston" to somewhere else.
What do you think?
