I would upgrade a slummy looking kitchen or bath with builder grade materials or do tweaks to something old looking but in good condition (refinish a pink cast iron tub, use oil based paint to cover dated bath tile in good condition, paint good condition cabinets white and add new counters)

With Amazon taking the old Euclid mall, about 800k sq ft, and now building a 1 million sq ft facility 20 min away in the heart of everything , seem as though pricing is going even higher.

Most posters say to use oil based Kilz, but are you also using some sort of enzyme odor remover prior to this?

It is a one 2800 sq ft building facility (built in 2004) on approx. 1 acre of land.

We installed a water well, fencing, a compacted house pad, and built an $80k barn/workshop.Before we could start the house, I got laid off (oil & gas) and we converted about 1,000sf of the barn to living space.

If the furnace had some specialized function, such as in a climate controlled self storage facility, then it could be a 5 year asset. 

You can use Google Maps (GM) to measure out 3 miles from your target facility.

An exception would be if the A/C or furnace had a specialized purpose such as in a climate controlled self storage facility or a restaurant walk-in freezer.

Have spent my entire professional career in Facilities Management and will be working on my Real Estate license this year.
