Housing - tips on finding an apartment or room in BU

My daughter will be joining BU this fall as a grad student in BME. She is going to visit later this month to look for a place to live. I am told housing in the area is a serious challenge.

Any tips on areas to focus on, neighborhoods to avoid, chances of finding on campus housing this late in the year will be deeply appreciated. Her budget is to stay under $1300 a month, preferably more like $1000 a month in rent. Safety and proximity are priorities as well. Any input on what her options are and resources for finding potential roommates would be super helpful! Thank you
