> correspondence set in Calibri looks like something dispatched from a leasing office

In general this is the way I feel about anything written in a Microsoft-, Apple-, or Ubuntu-supplied typeface. If you stick to system fonts you the pinnacle of embodiment of apathy in my book.

Have some backbone, browse through Google fonts, pick something that represents your organization and stick with it.

Even if you are a leasing office, pick a good font. That will make me more likely to lease from you because your attention to typography conveys to me that you will also be attentive to details in building maintainence. If you communicate in Times New Roman and Arial it tells me that you probably are apathetic about mold in the walls and electrical code as well.

While I appreciate nice typography like not many do (I decide on what editions of a book — especially classics — to get based on the typography and overall layout), I also appreciate that I may be easily swayed by good typography and land on a crappy outcome (I have several very lousy books that were done really well typographically :)).

So I'd never use that as a metric: yes, I care about typography, and if the content of the message is equivalent, I'll pick the one done better. But I do not expect everyone else to put as much weight on it.

If it's legible, the terms of a lease are way more important than the typeface. Anyone wasting time on the typeface of the contract would worry me more than comfort me with regard to knowing what's important.

That's... certainly an opinion.

Any typefaces you’d recommend?
