When I was on the job market with a two-body problem, I got this advice:
This is assuming that you already have an informal offer.
Postdoc or RAP type of positions are easy for the university to create. But
if your LD wants a TT job, then you should demand that and negotiate from
there as much as possible. If you start by saying something like 'I'm
flexible and can accommodate', then they will lowball you from the beginning
and it's hard to negotiate.
If you don't have an offer yet, then they just want to chat...?
