Lets say that the rules of your apartment complex are this: -max of two pets -no rodents (only dogs, cats, birds, and fish allowed) -all pets must be up-to-date on vaccinations -all pets must be monitored outside, wear a leash and have stool picked-up after -no dogs over 40 pounds Tenant A- elderly married couple and their grown son each work hourly-rate type jobs has a 12 pound dog allows dog to roam around outside without supervision does not pick-up after dog's stool the dog has had no training, no socialization, and can sometimes be mildly aggressive also has a caged bird keeps bird in ridiculously small cage with no toys or companionship small cage leads to bird being bored being bored leads to bird constantly squawking loudly neither dog nor bird ever see the vet- both in poor health and poor hygiene besides a dirty bird cage, the apartment is always very clean and well kept they always pay their rent in full, and generally they always pay it on time Tenant B- young married couple husband in the military, wife a stay-at-home student and mom-to-be (pregnant) have 5 pets one dog that is 48 pounds the dog is walked on a leash several times a day and the dog's stool is always picked up after the dog is in a training class, very well behaved and friendly one cat that is strictly indoor uses the litter box religiously (litter box cleaned daily-no smell) and three hamsters whom each have large escape-proof cages hamster cages are cleaned every week (no smell issues) all 5 of the pets see the vet regularly, are up-to-date on vaccinations and in good health the dog and the cat get baths once every month, so are in good hygiene the apartment is always kept clean and well kept they always pay their rent in full and they always pay it on time Tenant C- middle aged married couple with one young adult son husband works hourly rate, wife on disability, son dropped school and now is in an unsuccessful band has no pets however plays their music loudly keeps the apartment some-what clean...however not as clean as it could be pays the rent almost everymonth...however every month there's a problem: either the rent is late or the rent is not paid in full or both so who would you most prefer to rent to? who would you least prefer to rent to? this is interesting... I was worried because we had to renew our lease, but when I went in to the leasing office to speak to the landlord about our situation and how we had broken past rules she asked me this very question and I wasn't sure how to answer fyi- tenant A lives across the hall from us tenant C lives directly below us and my husband & I are tenant B idk why I was so nervous about the number of animals we have -we've never lied to our landlord, and we provide her with copies of all the veterinary documents for all 5 animals (I'm in school to be a vet tech and I've worked with the humane society as a groomer for several years before I married, so yes its important to me that my hamsters have medical care and that my cat be bathed regularly- quality pet care is what makes the fur-babies live the longest they can)
