Gut feelings and common sense are some of your best defense against a wacky tenant but once off their meds, breakup with spouse, or job loss, anyone can go wacky. 

Had a great first tour of the place to a well-qualified military med student.But he emails me back saying he only wants an agreement until end of year!!!

Win-win.At any rate, if you have law students or med students or other grad students (preferably not theater or music majors - they're flaky party animals), see if there is an off-campus housing listing for their grad students, or go talk to them about how to advertise to their grad students.You have to be careful how you word advertising on Craigslist or anywhere, though.  

You seem to be having a fight entirely with yourself about something off topic.Did you forget your meds this morning?

And I'd hire someone to go clean the place every week or ever other week, and include that in the rent.I've heard med students are also great students for the same reasons.Students are great - if you rent to the right niche.  

By the way, if there is any way you can just rent to grad students - preferably med students or law students or engineering students - just not art or theater majors (party animals!)

I heard med students are also great.  

Med students or law students are great.  

In fact, if I recall correctly, there is a built-in deferment for students starting their own practices (law students, med students).So, as long as the student loans are not in default, I wouldn't worry about them.

I've heard med students are just as good.
