They steal stupid stuff like people's flip flops. they party late into the night on weekdays. they behave as if residents are there solely to facilitate their good time and buttonhole them for information and directions when they're out walking their pets. they tailgate at the beach access because the hosts are too cheap to pay the association dues. they trespass on resident's property to fish and sightsee then become belligerent when asked to leave. etc etc etc.It really does degrade the character of the neighborhood and the experience of living here during the high season.  

I would lose the pet fee since they no longer have a pet.  

The lease said no pets allowed except if it's a trained service animal yet when we went to walk-through, They have pet dogs. 

Security deposit, pet deposit, key deposit.They are really good tenants, they pay on-time/early, no issues, easy to talk with.

On rental contract states no pets.

Love both cats and dogs, as long as the steady stream of pet rent is coming in. 

Yes about 90% of books are from Vrbo.I can automatically get a pet fee up front too.

@Hideaki YenYou just need to know a very basic understanding of accounting to get involved in real estate.Know that your gross income is rental income, late fees, pet fees, etcExpenses are items such as mortgage interest, real estate taxes, insurance, repairs, etcIf your strategy is cash-flow, your income should be higher than your expensesIf your strategy is appreciation, cash-flow may not matter as much.When you file your return, you will need a list of income/expenses from your rental property.Best of luck.

Especially interested in implications to others on the lease, security deposit (they also have a pet deposit), etc. 

A friend had the property management company secure a tenant who signed as a single person on the lease; without pets.
