We build almost everything out of concrete and steel with ceramic bricks that don't burn.

Many finishes like the laminate counters and fiberglass shower surrounds can be replaced with granite and tile in the future when the neighborhood warrants it (Tubs are new steel tubs). 

Also if I did go for top dollar flip do you think I would get a higher ARV going with a more modern look on the interior (White with stainless steel appliances brush nickel hardware, White bathroom tile etc.)

There’s a GC on one of the BP Facebook pages erecting a two story steel duplex in a matter of days.

We have redone the kitchen counters, cabinets, blackspalsh, added cabinets and stainless steel appliances.

Improvements after purchase - paint, new carpet/vinyl flooring, new blinds and all new stainless steel appliances.

When you add a brick 2nd story above it and you have a LOT of weight pushing down on a very wide steel (probably) lintel that will deflect over time.  

If the building is really old it may have galvanized steel plumbing which needs to be completely replaced - from the water meter! 

I'm sealing the existing plywood and metal floors, in lieu of installing flooring, and I'm also leaving the exterior corrugated steel as the siding on most of the build.
