PGY-1 here. (Recent Grad of Hofstra). Just wanted to clarify one pt. If you are referring to "prelim" list on 2016 Hofstra Match list, that's because several specialties require prelim (PGY-1 year prior to R1 year). For an example, a derm resident who is doing pre-lim at Winthrop will be considered a "Winthrop Medicine prelim"
We only have 1 true "prelim" from our class, and that's because he wanted to keep his options open for next year, as he was mostly undecided. Otherwise, all of us matched to a specific program (R years) +/- prelim (depends on specialty)
I don't think you guys have much to worry about residency at all. Many of my classmates stayed at home for various reasons, including 1) we had a large group from long island, and they wanted to stay home 2) You get student loan wiped out if you work at NSLIJ for certain number of years, and residency counts for those years.
Hope this helps.
