I bought two new appliances for their term and let them pick a new stove for almost a grand.

for this luxury 3Br 2Ba 1501 sqft, top floor unit with all appliances /fireplace/granite countertops, wood floors, large balcony with view of the city skyline-- gated community and secured building with pool and clubhouse)Now my PITI will drop to $1120..So I just more than doubled my monthly positive cash flow, put $24k cash in my pocket--tax free --and I still OWN the highly appreciating income producing asset.

I called the contractor and he said it is very ridiculous as the gas appliances are property vented to the exterior now without using the chimney and the chimney is no longer being used. 

@Kyle Mccaw Thank you I was thinking of light grays on the walls and white in the kitchen for the cabinets and white appliances for the neutral factor.

Potential issues that you might want to look into are zoning, the structural stability of the building if it is multi-story (flooring, people, appliance add a lot of weight per sqft).Depending on what type of construction the warehouse is (Pre-engineered metal building, block, bar joist, or structural) you might have good luck partitioning areas off for contractors, light manufacturing, etc.

If so, does anyone have any best practices for procuring appliances?

A couple of years ago when we were doing a project, I ordered all my appliances that day.

I would assume you want to budget for roof 25 year life, appliances and hot water heater 12 year life, hvac 20 year, etc.

Upgrade on the kitchen will include new appliances, upgrade countertops, paint, and floor tiles.

I was curious as to the rental demand for each unit if updated (floors, paint, appliances).
