I decided to go the turn-key route to start with because I still work 30 hours a week as a Labor and Delivery Nurse and I have two small children (3 and 1).

The first delivery was in 2013, the development sits on 63 acres with ~180 units, so far. 

If it is in option to buy the home upon completion and delivery?

It used to be The Financial Times but they stopped delivery in my area - I've moved over to books lately.  

Also, I have the most updated address so I'm 100% sure my FedEx letter is going to deliver. I

Often, they will give you a discount as a landlord, have delivery service available and be able to service what they sell.  

Be very clear with them if you want them to take the old appliances away upon delivery and also have a clear understanding on the delivery charges if any.  

This policy has allowed me to be consistent when dealing with late pays, flexible enough to work with good tenants that have the occasional problem, it encourages good communication with late fee discounts (I send out a letter saying next time you can save money if you let me know in advance...)discourages habitual lates (tenants save lates for 'emergencies')limits my losses (at most I'm out 15 days rent before I file for eviction)I'm probably going to add a fee for the delivery of quit or pay notices in all future rental agreements.

I work in the IT field and have been obsessed with working on my side businesses for a few years now, which include building websites and a donut delivery.

I understand your hesitation, but like most things, it is all in the delivery.
