NO pets..  

@Isla Arshad - Pets are a risk, but when there are more dogs living in houses than children under the age of 18, you will be isolating yourself from a large pool of potential renters if you say no to pets. 

Do I need coverage for damage by a dog (many residents have dogs in the area, but current tenants of this duplex don't have pets)?

Id ask if they smoked or had any pets, how many people would be residing there, when would they like to move in, etc.

Or if you have a no-pets policy, but see photos of the applicant's pet in recent posts.Some landlords even said that when checking social media account on one of their applicants, they found a post that said something like "the next house will be the best party house"Right now, I just google the applicant's name and find any social media accounts associated with their name.

Lets say you have 2 applicants who have 800 credit, excellent jobs, no pets, and are basically equal and wonderful.You still have to pick one, since they both cant move in.I let them know very nicely that you had several outstandng applications and you have signed a lease with another person.  

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

Address of the rental property.Names - all the names on the rental agreementHow many people lived in the unit.How many pets they had and what type.Did they pay rent on time?

For my tenants, I allow pets but they are responsible for any damage the pets do, even if it exceeds their deposits.

This was invaluable and I used many of the forms, including Pet Agreement, Rental Credit Application, Security Deposit Receipt, Tenant Information Sheet, Lead Paint Disclosure, Garage/Parking Space Lease Agreement etc.
