If you could answer those items I think we could provide some specific recommendations.

Assume 600 sf per unit. 1200 sf*$6 sf = $7200 /10 year life span/ 12 months in a year= $60 per month for 1 item.

A couple additional items to consider.

I also take pictures of the appliance information plate that shows the make, model, and other details in case I have to send a technician.

Get every form you can find, compile the items on all the forms and create applications and lease agreements that covers everything you find on those forms and write that information to cover your butt and to make everything clear, in the beginning, for what you expect from your tenants.

If you are referring to any additional cost to close in an LLC, there isn't a line item cost to close in an LLC.

That's the most important item. 

But I sure like how Tesla does it.. buy a car on line and never talk to anyone about finance  TEsla would make the finance manager job obsolete. and maybe that is where car dealerships will end up going they will all start to model Tesla super cool way to buy a car.  

You should take each major item (roof, HVAC, exterior paint, etc) estimate replacement cost and lifetime and use that as Capex reserves.

For each item that we felt was above and beyond what was immediately obvious from a walk through and would substantially affect our rehab budget, we included photos or excerpts from the inspection report, as well as an estimated cost for repair.
