Here Comes Happiness (1941)

With the moral and financial support of her self-made millionaire father John Vance, coined the Copper King, Jessica Vance ditches her engagement announcement party - the engagement to Jelliffe Blaine who she doesn't love and who she believes doesn't love her, but rather only her money - to find true love from someone who doesn't solely love her for her money. In the working class apartment building into which she moves, she quickly makes a new group of friends who don't know about her wealth, she and one of that group, Chet Madden, who fall for each other. What Jessica likes about him is not only he being a real person, unlike the calculating type that Jelliffe is, but that he wants to make something of himself. He works as a commercial building washer, but is taking business classes at night school in an effort to start his own building washing business. In their love, Jessica knows the longer she waits to tell him that she is heir to millions, the more difficult it will be. But in Jessica clandestinely trying to help him financially with the startup of his business, some misunderstandings occur which could kibosh their relationship altogether.
