James DeRoest what about those tenants who have a good credit and no evictions but are the ones who don't take care of the rental and who other renters always complain about noise or other issues.

For example, no rice, pasta, grease or oil, for these gum up the pipes terribly and bring most disposals to a grinding halt.

Even if your college guys don't cause noise problems with the neighbors, they will probably want to change roommates fairly often.  

The owner was very against renting to students, because of the noise problems, etc.  

One of his tenants had a police visit due to a noise complaint. 

Then, she began to rudely complain that my industrial tenants were making noise that bothered her illegal tenants.

This building has few vacancies; my daughter finally got in when she evicted someone because they made too much noise.

No smell and no noise.

Then you are not open to all pets yet not closing off the possibility altogether....So, for example, one small well behaved dog you may approve  (especially one that a previous landlord says was not a noise, damage or other problem) but a pack of loud unruly ones not so much...And you can refine some of what you are looking for in terms of size, behavior, numbers, breeds, ages (no puppies without house training for me, eg), even spaded/neutered (especially for male cats, etc), references (ie how the owner did with a pet in past places), etc... 

They are really working in the noise of the issue not doing anything meaningful other than hurting tenants if anyone.Before all this came up I'm not sure how many landlords actually knew about the exceptions.
