Pets.......yes pets.  70% of renters have pets.  

Co-living spaces, communal workspaces, rooftop gardens, fitness centers, and pet-friendly facilities are increasingly popular among Millennial renters and homeowners seeking a sense of belonging and community engagement.Impact of Demographic Diversity and Inclusion: Millennials are the most diverse generation in U.S. history, with a significant portion identifying as racial or ethnic minorities.

They can implement or may already have rules like no rental signs, HOA needs to approve any application (but they might only meet quarterly), no pets for tenants, owner must live in the house for 1-2 years before renting, no leases less than a year, limit on # of rentals, and more.   

We rent property short term and allow dogs (up to 2, 50 pds or less, pet agreement and $100 pet fee). 

First the approved tenant moves in: perfect applicant, single mom with one kid, no pets... soon her adult kids move in with their kids and then her ex moves in with his kids and their kid's kids and their pitbulls and mastiffs... 

Seems like cancer patients and transplant patients want MTR...may not want to stay in hotels...may want someplace pet and family friendly and want a host with a heart that can shorten their stay---Say YEAH....or extend it, without paying big penalties.....and these are people often networking with other patients and families who may be your clients too. 

Hello,I am getting all my property management documents and software in order before I buy my first rental property so that when I buy it will be a smooth transition, Beside the lease and application, what other documents should I have in my files so that i am prepared (pet agreement, inspection checklist etc.) .

Where the tenant puts his info out there and what he's looking for, # of pets, what he can afford,  etc. 

For room rentals, do you allow pets?

He did mention in his Ad “ no pet”.
