Depending on the brand name of equipment, you may have parts-only costs of about $2000 for a bare bones unit and ducts to $4000+.I would infer as to the equipment brand name and costs. 

The goal with the 36 cut is to get the existing floor to bare wood, take your time with this cut.  

For example: should I buy the $100k homes and barely break even on rental holds until the revitalization is complete and sell?

Rent in some places climb 3% with barely any upgrades.

If you are going to rent it out do the bare minimum and rent it. 3/2 in james island or west ashley should rent for 1300-1500 before renovations and not much more then that after the reno right?

("Set your real estate on auto pilot") When it comes down to the bare facts unless I've done one deal I can't understand heads or tails of what to expect.

I have already  learned much more than I could have if I would have spent the cost of pro somewhere else, and I have barely used any of the pot benefits yet.

Just fix the roof, give it a good cleaning with appliances off of Craigslist make sure plumbing, heating and cooling works and is safe to live in (no bare wires, black mold, smoke detectors etc..) when you are ready to sell it than that's when you would want to upgrade it.Good luck Wishing you success;) 

@Casey CarrollThis is all new to me so bare with me please......So, the NROC is basically insurance for the owner to protect their property while you're renting, until and IF you dicide to buy...
