My limited qualification is that I analyze, buy, and sell several beat-up houses and land each month.Objective, non-opinionated summary: Councilman Darrell Clarke and the Strawberry Mansion Community Development Corporation have pushed a zoning overlay that prevents higher unit density on land, building heights, roof decks, and other development characteristics non-homogenous to the current neighborhood aesthetic. 

Only use chrome if aesthetics are an issue. 

My understanding is that both will require maintenance but steel is ultimately more durable, fire resistant, and generally considered more aesthetically pleasing.

Love that you are utilizing a DADU for this method and you approached the stylization, design, and overall aesthetic with an STR mindset. 

Verify the specifications for 203k rehab loans - I was under the impression that they can be used for "needs" (house *needs* a roof or hot water, house doesn't *need* granite countertops and new cabinets) and not necessarily so much for aesthetic upgrades.

(pictured below), but after applying these, you'll still want to manually review each comp and determine how close the "finishes" (flooring, appliances, aesthetic, door handle...) are to your target property.And THEN, you'll still want to consider if whoever is managing/hosting the listing could compete with (or beat) the listing quality of your best comps.

They just want to get in, get out, and move onto the next.To be fair, I had an "aesthetics only" rehab (20k give or take?).

Aesthetics are important.

I would remove it for both aesthetic reasons as well as possible foundation issues.

Then design it aesthetically in a way that would be attractive or inoffensive to 8/10 of them.
