As an owner, I don't like to read the above comments as the landlord does not know the potential renter and is painting with a broad brush, then hurting feelings with an ignorant comment. Tact can go a long way.
I have seen extreme differences in the students I rent to. Generally speaking, the ones with strong GPAs do the following: pay their rent on time, notify me if there is a water leak, notify me if something is broken, reply to my text inquiries within a few hours, and generally rent responsibly. We have a big investment we protect by renting to responsible students. In return, they live in a decent complex with a great location, have an owner who upgrades and improves, keeps the place in working order, communicates when water will be shut off in the building due to maintenance, or parking lot interruptions, etc.
Further, as young adults, it is time for the students to arrange these things on their own. If I see a parent who is super involved, part of the rental process, wants to take the tour with the student, that is a huge red flag for me, as it typically means the parent will be over involved in other situations that are normally handled between the student and owner, and it greatly complicates processes, communications, etc. .
A rental agreement can be a positive situation, and I strive to make it so. I reject that the owner/renter relationship is inherently adversarial, and part of the groundwork in that is renting to students who demonstrate responsibility, treating them like the awesome young adults that they are, and keeping communication lines open with clear expectations.
Because they typically do not have a viable credit history, as they are young, the GPA serves as a type of credit history. Yes, of course students can be responsible and have a low GPA, and my own son is in that category, and he is not a partner. That is why I always take a personal reference as well as a work reference, make those important calls, and find out more about the character of the person who is going to take care of my investment for the next year. I love the personal reference calls, as I get to learn about these neat kids, how they mowed the lawns, raked the leaves, watched the dogs, etc., as these kids were growing up. Always fun and interesting calls.
Yes, many kids love to party, the occasional door gets knocked off, the occasional room smells of pot, and typically there are some bottles of liquor on top of the fridge. I recognize all of that. I charge the kids for the door repair, , I tell them to stop smoking pot inside as it is stated in their lease that all smoking is outside and give them the cost of repainting the room with KILZ then regular paint (aboout $400) and it stops. Kids who are responsible typically own their mistakes and move on. A strong GPA is a strong indicator of responsibility. The statistics agree with that and so for every strong correlation is an exception, which I take into consideration.
