During the rehab he send me the invoices and what needs to be paid and as some of the stuff that needed to be fixed was bought from places like home depot and i could not transfer them money I gave him the company credit card (i made sure there isnt much money on the account and was monitoring it on daily basis).

Additionally, since the banks make you sign up for auto pay to obtain the HELOC, I'm guessing they're hoping that you just forget about monitoring the payments when the interest rate reverts back to the variable rate.  

I have rules of no outside dogs, only out while owner at home to monitor there  noise level and there safety. 

Do you charge for monitoring and maintaining vacant units?

On top of that, they can sleep at night without having to worry about whether their property is managed.Some of my owners have enough time on their hands that they could possibly manage better on their own because they can drive by the property every single day, inspect every 1-2 months, monitor every penny, spend six hours on the phone procuring the best bid for a maintenance issue, swinging their own hammer, etc.

The kitchen is full of old moldy food and nasty gunk everywhere including inside the dishwasher, walls from top to bottom just dirty and sticky, with wax etc. all over everything, Every smoke detector, carbon monoxide monitor pulled of the wall, trash stuffed down the bathroom drains, 100s of holes in the walls and ceiling (her stripper poles) etc., Just gross.  

Apartments notoriously have tons of frivolous claims and an important part of your risk management plan should be requiring a monitoring renters insurance of your tenants.

Will also be installing internet on this unit so I can monitor my stuff via my IP Cameras and using the basic services of the unit (gas/electric) as I plan to have a refrigerator there. 

Please let me know your experience with cosigners and if you would have any problems with a parent being a non resident lessee so that they can monitor condition and have a little more control.

Perhaps they will monitor the dog better, if they keep getting billed for ongoing damage.
