I have an applicant with a service animal that is interested in my property, which is a 4-unit building that doesn't allow pets.

Some people have their accounts as public and some are set to private so I can't find it or see any activity.I check the social media profiles to see if they have any pets or excessive partying lifestyles because some of the units are in quiet areas with mostly elderly people living there and there is a strict no-pets policy. 

First let me start off by saying that this thread is for those animal lovers that have pets and consider those pets to be a part of their family.

They decided to bring their dog and pay the pet fee and pet deposit.

Both units were vacant and the 2/2 received a tenant first (seller has expressed that they are very picky-no pets, no college students).

My personal pet peeve is when investment managers provide long narratives on the economy, the geopolitical landscape, provide reckless forecasts, and opine on other macro topics in their quarterly updates.

Other than the potential for physical property damage caused by the pet, what kind of liabilities does the landlord open themselves up to when allowing tenants with pets?  

Make sure they will do the credit check, background check, show the property, generate the lease, discuss up front what credit requirements you require, what pets you will accept, etc.  

Also, people with pets usually post pics of their furry friends online, informing a landlord if the potential tenants are being honest when they say they have no pets.

Maybe having business cards on you at all times and handing them out like candy, or telling everyone you know and their pets that you buy houses.
