Letting Tenant Pay Months at a Time?

[Lindsay Wilcox]

Just got a question from a prospective tenant and wanted to know what you think. He's a college student and receives his student loans in August and January, so he wanted to know if he could pay four months' rent at a time.

I don't see any reason not to take him up on it, but am I missing anything?

(Ignore the fact that college students are often irresponsible. He comes very highly recommended by people I've known and trusted for years who know him in a professional capacity and vouch for him.)
