They didn’t completely destroy the house, I did keep most of their security deposit and used it for the repairs, along with some of our own cash.

I’ve never had a problem with a lender when I showed them the deposit that was made into that account.

Money was deposited into my account the day after checkout.

Renter's Insurance is a cheap date for the tenant; it protects their security deposit and assets. 

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

We were not able to recover any yard damages due to other damages they had left that needed repair, which empted out their security deposit.

I don't rent furnished and others may be able to point out where this is flawed, but I would consider renting the furniture SEPARATE of the unit because that may allow you to collect a deposit on the furniture.

Leases are signed electronically (esign.com), and I set them up with RentRedi for deposit, cleaning fee, and rent payments.

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.

I have a clause in the lease that says the security deposit will be held in so and so bank with so and so address and interest rate will be xyz.
