Houston, We Have Tenants
And they don't seem to be quite as green as we feared; they mentioned that they're looking into renter's insurance, which is something that never even occurred to me until I was a good dozen years older than they are. Also, they asked very nicely if they could have a new shower head.
In the last week we've fielded dozens of calls and emails, showed the apartment to twelve or fourteen prospective tenants, but received only six actual applications (two of whom each called back within a day to say they were taking another place). I've now had enough excitement for the next year or two and now just hope [karma being what it is] that these guys don't do what we did last year and ditch us for another place in the next week.
Also that they're really as low-key and unassuming as they seem. They mentioned that their big social event is video game parties on Sunday afternoons. I think I can handle that.
