It's way easier to keep clean.As I look for property to buy, there's no way I'm going to buy a property and pay a premium for a flip where they installed a bunch of light colored carpet for a rental. 

The bathtub tile is vintage but that's a color that has come around to being popular again so keep it.

What the owner I managed for did, was he used the same color paint for all his properties, and when a tenant moved out, he'd just paint from the floor up to wherever he had to do any patching for nail holes.  

By the time you recoup it, the new color will be something else.The only upgrade really worth doing, in my opinion, is laminate or wood flooring.  

These days the difference in floor urethane oil v water is color. 

I'm up there in years now and I've seen fads come and go, and have dealt with different landscape issues and pests and dust flingers and accent walls, and many different types of decor and colors that all went out of style almost as quickly as the stainless steel appliances and gray walls went up....oh, I meant avocado green, no wait, I meant gray and stainless steel are the new avocado green....Anyway, if you want to go with timeless and save money in the long run, you can't go wrong with white and clean, in my opinion. 

The color scheme for the paint job, matching the lights with the faucets and all that good stuff.

What color?

I even used a poly with a color built in over my floors and It looked great!  

Going an inch wide and a mile deep is a more colorful and engaging way of saying that it would be wise to pick a very specific target market and a niche.Unless you have money to burn, you are better off choosing a specific target market and drilling down.
