I'd put some outdoor type of tiles, but use whatever is appropriate aesthetically.2. 

Home was in great shape just needing some aesthetic updates and remodeling to personalize the home.

May add a little additional value due to aesthetics.3. 

Thanks anyway.Best, MelindaHi Melinda:  this quote of yours came from the other duplicate thread to this one.As I mentioned in my post above, getting the exposed existing structure aesthetic won't be practical. 

These are things cash buyers and future home buyers (who will likely finance via banks) are wanting to see proof of even if the surrounding properties aren't presently at their aesthetic best.  

I may later this month with a rehab, but I have no experience yet.However, I agree that having an exposed tank in a living area is not aesthetically pleasing. 

Visuals go a long way to help the aesthetics of a property. 

Mostly cosmetic with cost effective touches to the bathrooms and kitchen to improve aesthetics What was the outcome?

However, if I had the money I could easily find uses for $30k in improvements (Debating between aesthetic and functional improvements).

As @Chuck Kramer mentioned, there are a ton of 4-7 bedroom high end new construction properties being finished this year and next, so you'll want to make sure that the aesthetic of yours will be unique enough to be competitive when all of those start entering the rental market.
