In your CAMs charges, do you include the fee for a management company or manager?  

It's a cheaper neighborhood and it's turning more towards a rental neighborhood, but it's still in a good part of town and Frenship schools.

To me, not charging a deposit at such a high price can really benefit/reduce the move in price of a new tenant.

Does anybody have a cheaper suggestion?

What would be an appropriate charge for water passthrough?

Not all properties have an HOA/maintenance/common charge fees.

If the unit is damaged because the leak was allowed to continue, I would charge the tenant for the additional repairs required.If tenants have such obvious lease violations, there is a high risk of additional problems down the road.

If you qualify for conventional loans, bank financing is available to use for flipping and is much cheaper than hard money, but also slower and more headaches.Remember that buying a house requires money, but it doesn't have to be your money (although it's simpler if it is). 

As an aside: Contact your credit card company and tell them what happened and most likely you'll get a 'charge back'.
