Pets?

One had reference on their contract for owning pets and the other one did not, but both tenants had them.  

I recommend to my owners/customers that we do not allow pets due to the possibly of a dog bite or damage.

When they get a pet and they are not willing to pay the pet fee, what happens then?

I allow pets in my rental and having the back yard fenced is a way to increase rental revenue.  

Self managed, no leases on any of the units, missing deposits, pets with no pet deposit, and friends staying in unit for below market rent.

Do they pay on time, pets, lots of calls, what the place looked like the last couple of inspections.Quarterly seems very frequent and most tenants are going to push back....... unless there are real issues or concerns, I would do it that frequent.The typical move in/move out form work fine... you a can add in some more details like checking the water heater and HVAC, applicances more thoroughly etc

They are mostly single female, maybe with a pet, and will want a safe location and probably nothing too big to have to maintain. 

I accept pets.
