Affordable Apartment rentals in Boston?

My life partner and me anticipate moving to Boston in August. While hunting down flats, I am recognizing numerous lease dates begin in either June, July, or Sept. Is there a reason I can’t discover a begin date in August? I thought I was looking excessively soon, however, there are heaps of posting for September. Any criticism or recommendations would be incredible. I have fundamentally been seeking Craigslist. Much obliged!
