Mystery flowering shrubbery…ID help requested…

A friend of mine up in NJ bought a rental property and it had these bushes on it...I've not a clue as to what it is (not familiar with what grows up there in the NE), but I told him that I'd ask the knowledgeable folks in the gardening forum about it... He said that the flowers didn't have any discernable scent, if that helps... Many thanks for any help!
