From a marketing end of things, think of Pain vs Solution. While having some brand information on some pages is good, most people will not care too much about it. People searching have a pain (needing a place to live) and want a solution (apartment for rent near 84th & Dodge St).
If you position your Titles (and descriptions) as a 15-second elevator pitch, that's essentially what searchers are looking for. The brand is less important on MOST pages, but good to have on both the home page, contact and about pages.
Also, we're huge fans of having a different Page Title (in SERPs) than that of an H1 on the actual page. They don't have to be the same, and for all intents and purposes, they shouldn't be the same.
