In my latest article for BiggerPockets, I discuss the types of renovations that are better left undone. Yes, these renovations may add a little value to your property, but they are almost never worth the cost. In the article, I reference my own experience as well as a 2003 study from the NAR.

The study found that the following upgrades added the below percentages to the houses' final sales price, all else being equal:
I think that list alone is a good start to what makes sense to add and what doesn't. But I go into much more in the article, so it's worth reading if you're in the business of renovating houses.
