I look at a 12 month commitment with a rent of $5850 + a $5850 security deposit.

While separate accounts sure helps with the audit trail, it's not necessary if you note the reason for a a deposit and withdrawal on the drafts or "source" document. 

Otherwise the background check features, having a pre-set but editable application, direct deposit, rent reminders to my tenants, and automatically adds late payment fees (should that be needed). 

I’d then deposit the, still sealed, envelope into a USPS mailbox.

Young couple..... young wild puppy breed..... want to breed and have even more young crazy puppies all over your unit.... sounds great....lets do that... the pet deposit is 15k. :)Deny but dont cite a specific reason.... you have selected another candidate. 

And California also capped security deposit, thus literally robbing landlords by AB 468 that's faking human right issue.If there is class lawsuit, I want to be the first to jump on.But my question is, why landlords are so docile to this evil law? 

Then charge her pet fees, pet rent, additional deposit and additional rent for the extra people and demand a 2 year or longer lease.Then you can get them a second room and find a place that allows dogs.Red roof Inn is cheap.Maybe just do a couple nights while the bathroom is being redone and have contractor work around them for the other stuff Tell the contractor you'll give him a bonus if he can work longer days and finish sooner.

As a general rule, it's best to learn how to handle problems before they become problems. make a list of the potential problems you could face as a landlord: rent rates, marketing, collecting deposit, late rent, unpaid rent, abandoned rental, early lease termination, unauthorized pet, etc.

If you have a pet policy, they must meet breed restrictions and pay pet fees, deposits, and rents.

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.
