With new bathroom, widening one bathroom door, upgrading a toilet in master, granite on kitchen island (had ugly tile), hardwood flooring, upgrading lighting in dining and kitchen to can LED lights and paint, we spent about $19K in upgrades.

So I don't know the real rules on that.I know crews that can do new cabinets and granite counter, and simple backsplash in a weekend.

New flooring with warranty and robust sound barrier underlayment, beautiful new granite countertops, updated stainless steel appliances (refrigerator, stove and new dishwasher), in unit laundry, outdoor maintenance, snow removal, and garbage included.

I'm leaning towards finishing because I want to be sure that they know all of the finishes are final, that I didn't plan on switching to granite counters at some point lol. 

they have designer colors slab granite in baths and kitchen.. all new HVAC Plumbing is all replaced along with electrical and roofs windows insulation etc.. average rehab 80 to 100k.

For that market, I rehab the properties to a higher modern granite standard.

We may upgrade to granite at the end (another $1500 or so), if we're doing okay on budget.  

Yes, you are correct, they would pull the plywood and the tile off and install the solid surface/quartz/granite top.

1/2" drywall with plastic fixtures, particle board vanities and cabinets, and fha minimum grade throughout or 3/4" drywall, 10' ceilings, granite, wood tongue & groove cabinets, deep sinks, 9" faucets, smooth stucco, and full interior trim?

In Atlanta, standard construction using mid-range finishes (granite, hardwood, etc) is running us $60/sf.I have another thread here on BP that details one of these builds with all the costs broken down...
