And of the stuff that is cheaper it's very hard to find something that you won't have to carry until rent appreciation makes it cashflow neutral.

Neutral palettes are key.  

@Tim Richardson I think you will find that most everyone goes with a neutral color to appeal to the masses, and there are threads on BP complete with before and after pictures. 

Bernie Madoff,  Enron, etc. etc. weren't at fault: it was the investors who were the true guilty party.Also, I would suggest that as a crowdfunding portal owner, you may not have the most neutral opinion on the subject. 

Here is what I can tell you:I will call a title company at 4:53 PM on a weekday, expect them to pick up the phone, and confirm within 2 minutes that they have a notary that can sign someone at 10 AM the next day.If they do not meet my expectations, that is a big fat negative mark in my book.When they do meet my expectations, as they typically do if it's a local branch with folks I've worked with before, it's a neutral mark in my book.Your market may be different, I don't know, but that should give you an idea for what someone in RE professionally expects from any decent title company. 

I typically go with a neutral ceramic tile in the kitchen and baths, vinyl plank in other rooms.

I am guessing it may even be a third alternative on value: neutral...

To stand out from the competition, I give the choice of single neutral paint color to prospective tenants.

Electrical System: A garage outlet has hot and neutral reversed.

Although, you might have to refinish the hardwoods to get the oder out, because if it has seeped into the wood and subfloor that will be hard to remedy with sprays and neutralizers.
