Most turn keys have there standards and your right there is no parity to it.. so a buyer should get a rehab scope of work and compare exactly what was done and then have a 3rd party inspection verify that its done as noted.

I was planning to just install the single piece 22" depth formica tops from HD and cut to fit, but notice the diagonal piece above the DW which is deeper than the 22".

The diagonal has HUGE shoulders.You could find a SFR in Longmont for under $500 - You could find a DUPLEX for under $500.

Come to NYC and you'll see brokers pitch MF buildings with cap rates at parity with 10 yr treasuries.

Inside in an old home, I want original 3/4 in. oak floors, and ideally diagonal 1 in. subfloor planks.

There's a railroad track that runs diagonally through it... which may preclude it from residential use.With the general lightening of attitudes towards Marijuana, I know certain areas have made it easier to cultivate it.  

The appraiser for the most part cares little what upgrades were done the value can only go so much with respect and consideration given to the other sales in the area so if you know the forecast for the pending sales, and completed sales are only 60-70k higher and your superior product may only be 80-90k in value  higher than your acquisition price, but your rehab is 100k in cost then you might want to scale your rehab down to 50-60k to ensure that you'll atleast get 1:1 conservatively with the money you spent on your rehab or maybe you dont even do a major rehab but a light rehab to get 2:1 parity  (1 dollar spent to 2 dollars created in value) so that you'll have enough profit to make some extra equity for yourself for risking your capital and your time in the rehab.

Something small that will still maintain parity in the relationship. 

 So far I've only done long-term buy and holds.An upportunity has presented to buy 6 acres in an up and coming area to subdivide and develop a subdivision.There is an easement on the property with powerlines that goes through  most of the property diagonally. 

I had to remediate the absestos adhesive under the resilient flooring in the kitchen and large pantry before I ripped all the luan plywood up and the 3/4 oak flooring underneath it with plywood over the diagonal planks, then cement board, then tile.
