How are you going to manage the day to day trial and tribulations of dealing with a contractor and dealing with all of the aesthetic decisions?  

We will keep that wall and live with how it looks aesthetically. 

So speaking from an aesthetic point of view I think it is an option.

The kitchen was the trickiest part of the house due to a VERY poor original layout - but I did my best to make it the most functional and aesthetically pleasing kitchen I could. 

This year we installed a new front yard at my personal residence and I didn't like the aesthetic of the cookie cutter xeriscaped formula.  

I don't see why it would be a problem but playing devils advocate, maybe the rental manager would rather wait for a finished project to show rather than an undergoing project only because perhaps someone does not like the aesthetics of the bathroom (tiles, vanity, etc) after they've committed to the rental (security deposit, tenant screening, etc).  

If you have no information on where the floor originally came from, how would you go about finding the right match of both aesthetics and interlocking mechanism to match the rest of the floor which really doesn't need to be replaced?
