What do you do to ensure that the tenant is responsible for security deposit disputes since that is the largest reason for owner lawsuitsHow familiar are you with the newly changed laws that can affect you the owner if they are not used correctly?

if you have an LLC and both properties are under it, you just need 1 operating account.If both are under your personal, 1 bank account specifically for the rental is enough for operating.Security Deposits should always be a separate account altogether.

If they fail to pay, then you can choose to try eviction or just hold the charges until the end of their lease and collect it from their deposit.

It's written into the lease that tenants must deposit their rents into that particular account (either by online bank transfer or by walking in a check/cash); I do not collect rents directly, nor would I if anyone asked.

If you can get your direct deposit moved against your heloc right away, and then you do not have to pay bills instantly, you are leaving your idol funds offsetting a 7.5-8.5% interest rate.

If a bank has to pay out 5% to get deposits then they usually want 7% to lend back out or it's not worth their time.  

-When a tenant moved out, the management company refunded their security deposit but failed to account for damage, such as holes in walls and outlets ripped off the walls, leaving me with repair bills and also tenants moving in without the repairs being done.Stuff like this that is consistent and when I ask questions they are defensive, when I ask for more quotes for high ticket items they are defensive. 

.: You don't need insurance or a deposit.

First of all it's very rare a seller gets a buyer's EMD deposit for buyer's financing falling thru.
