My oldest is 18, in her first semester of college, and should be house hacking in 2025.

They used the tactic that we would spend the same amount on a semester at college.

@Michael Plante my tenants pay monthly (although I have heard of others in various markets charging by the semester or year)

Typically those are shorter stays as they are doing something for a couple months vs staying for the entire semester or year.

You could easily have any two of the areas mentioned (in some areas one) consume 8 hour classes, 5 days a week for an entire 6 week semester.

Lately, we've had a great deal of luck with one particular university referring us to visiting professors who are often from overseas and in to teach for a semester.

Your new potential guests are insurance companies for homeowner displacement (flood, fire), buyers looking to move to the area but not sure where they want to be, sellers who want to sell but have nowhere to go, contract workers in the area, adjunct professors on a semester job, etc.

Such as extended periods of vacancy between semesters...I have a MTR that is close to a university campus and my current tenants are students, but they also passed all the usual tenant screening in the same way that I've rented to other mid-term tenants in the past.

Are most of the renters students that move out when the school semester ends?

I've rented to a few medical students and professors who are at a college for a semester or less. - The tenant type will help you determine the best areas.
