3) What should a pet fee be?

Plus any damage or cleaning that resulted from said animal.That said and more to what I think your question may be: I don't think you can bill the tenant just because you found out they had a pet without citing, depends what your lease says. 

This includes checking their credit history, employment status, and references.Set Clear Rules and Expectations: Clearly communicate your expectations and rules to tenants, such as rent payment due dates, pet policies, and maintenance procedures.

and you never know when someone's phone battery dies on their way to the property....no directions...well then maybe they can't find it....if they're from another country without a local SIM card....very possible in Dallas..then written directions can be vital..not just see GPS.......so that's why things like directions are important.Do you allow pets?......

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.

It could be mold or pet damages.Large gaps in the foundation.

Normally, when we perform the initial inspection noted above, after we have completed the inspection, we will ask questions of the Tenants, confirming the terms and conditions they are under; inquiring if there are any unresolved maintenance issues; confirming ownership of all appliances; confirming parking assignments and vehicle ownership/responsibility; confirming pets/no pets status; verifying number of occupants, etc.

PETS not pents =)

- That is one of my pet peeves . . .
