Although it is not the most aesthetic look, all it needed was a deep clean to look new again.

From an aesthetics perspective, what are the go-to renovations and supplies needed to be done and is there a particular order to do these renovations (I.e., flooring first, then walls, etc?)?

Unfortunately, on some structures the taller height destroys the aesthetics of the building.

@Adam Craig seems you have the right plan by making modest aesthetic improvements to get the property into a more attractive, marketable condition so that when potential tenants walk through they are not distracted by the distress etc. 

@Carl Boswell carpet on the stairs and through the landing does make perfect sense in terms of aesthetics.

This is partly aesthetic but it also seems practical since I want to operate my real estate business as a professional.Lastly, the bank has of course given me a residential property loan so even if I were to set up the DBA, my mortgage will be paid using through a personal account.

(some may be concern more with aesthetics, some with functionality, and some with being cost effective: so you have to understand and know what combination of all of that and balance of those you want for your project). example: sometimes I work with home owners or investors that want a good balance of those... or sometimes, some clients say to me...Sebastian, I don't care about saving money (I don't want to over pay) but I am not concern with budget to a realistic extent. :) I also saw: 4900 270th Ave NE, Redmond, WA 98053Listed for $700k (2500 sq ft) but it looks to be a fixer : @ $277 per sq ft with a huge lot: (I don't know if the same market as the home above: and where your realtor would come in... ) but if you look at this: you could buy something like this and renovate it: and add the ADU : 1000 sq ft for about $150k to $200k all in: where you spend $100k on the main home: and now you are all in for $700k + $100k +$200k : total $1 million (which is less than the finished home above).
