It's unintuitive, but it turns out that borrowers who write long descriptions tend to default more often. You are statistically better off investing in borrowers who write little or nothing.
I speculate that maybe it's the liars that do a lot of talking, when it comes to loans. And people with good credit mostly assume that you are going to rely on what the data tells you anyway.
My personal anecdotal experience is that it doesn't matter one bit what someone has to say. But it DOES seem to help if you avoid borrowers who can't spell and/or ignore grammar and/or don't know the difference between there/they're/their, that kind of stuff.
