Hi, I was in the first class and am now finishing M1 at CUSM. I thought the MBS program was solid, and very intense! They've made some scheduling improvements for the second class, and the new program director who came on board in Spring of 2019 is outstanding. It will be a lot of work still, since you'll have 8 courses at a time. There are some opportunities for research - reach out early to the various MD student groups The jury is out on how strong the linkage to the MD program will be. I believe there are only 10-12 students from MBS 2020 applying right now, plus a few from MBS 2019 who hadn't applied last year. See earlier in this thread for admissions stats for MBS 2019 who applied last year (10 of us are M1s in the MD program now).
CUSM can give you a list of housing options; you can also check the usual sites: Craigslist, Realtor.com, Trulia, Zillow, etc. There are some newer apartments and townhouses right near Arrowhead Regional Med Center (ARMC). There are also houses to rent nearby. Many students grouped up to rent houses which is an affordable and comfortable way to go - rents are around $800 per person in a shared house. You can pay a lot more for one of the newer apartments, e.g., a two bedroom at Circa2020 in Redlands is more like $1200/person and one BRs there are as high as $1800. Other apartments (especially right around ARMC) are less expensive. Most of my classmates lived in Redlands or Grand Terrace or Loma Linda. When classes move over to the new building (hopefully whenever school starts up again in July or Aug), the closest towns will be Colton, Rialto and the city of San Bernardino. Ontario, Fontana and Rancho Cucamonga are more upscale suburbs to the west of ARMC on the 10 freeway. Many students live farther away in a different direction: in Riverside, which is a university town and has a more urban vibe (and is also on the way to the beaches in Orange County). Some live even farther in that direction, e.g., Corona, Chino Hills. A few brave souls commute from LA which is a 1-2 hr drive depending on traffic. In sum: you'll have plenty of housing options.
