My argument is that when investing in a property with few units, you need to count every penny and following a statistical formula is not always a good thing. 

Project Managers are not the same as General Contractors.As a contractor I've installed 10's of thousands of ft of cat5 & 6, copper, fiber, core drilled & hundreds of racks, millions of punch downs so IT can commence

Concrete resurfacing or coatings? 

So many landlords refuse to spend a penny and their asset just deteriorates to junk.

When using my software it is very simple to use and records are accurate-to-the-penny.

I am in the Subto program and would say it is worth every penny!

If it's in good shape, I put a couple of coats of paint on it to seal it in.

I decided to rewire the entire 4 bedroom 2 bath house because it had aluminum wiring.My helper and I tore out the entire aluminum wiring and installed copper wire (to code) Outlets, stoves, heaters, AC Units, washer, dryer, lights and so on.

Especially for kitchen stuff...literally pennies on the dollar.

The White was too pink/orange, even with the White mixed with Natural.We also had the contractor "pop" the wood prior to the stain application, which is lightly coating it with water.
