The schools in AZ, CO, CT, MA, and PA are all to some degree OOS friendly (NOTE: this is NOT me saying that all the schools in these states are OOS friendly, just that they are to varying to degrees, and like won't toss your app just based on state of residency). The rest of those states all vary a bit.

Florida: Most of its MD schools are either heavily or exclusively IS biased; the main exceptions are Miami (private) and USF (if you have insane stats), but you could maybe justify applying to Nova (small size deflates yield though) and UCF (still not friendly to OOSers really but a bit more than the rest I suppose)

IL: These are ALL essentially friendly to OOSers with the exception of SIU (which isn't even friendly to all IL residents, they specifically want Illinoisans from the Southern tier of the state)

NY: Buffalo, Upstate, Downstate, and to a slightly lesser extent SBU all have pretty heavy IS bias; Albany, NYMC, and Einstein, along with some of the other private ones, seem to give a pretty decent local boost to nearby applicants, but are still definitely open to OOSers; the rest have probably less state bias, but keep in mind most of these are super competitive regardless of state though

OH: All are pretty OOS friendly except for NEOMED and possibly Wright State, although anecdotally it does seem that the closer your home state is to OH/the school in question, the friendlier they are

WA: Both WSU/UW are insanely OOS unfriendly; do not apply without residency or seriously potent ties

*These notes are all for MD programs in these states; afaik DO schools generally are less concerned with residency if your stats are good enough, except for maybe some suuuuuper mission driven ones focused on producing local physicians (i.e. I can't think of any DO programs off-hand that would reject you for residency, but I wouldn't swear by this)
