What areas have produced the Best ROI?

[Raun Stout]

This will apply to both flipping and people who are possibly going to remodel in preparation to list a SFR.

I am wondering what has proven to be the areas or specific items that have produced the biggest return when putting dollars into a home?  Especially if there are any things you have done to a house that turned out to be very popular or big flops. 

Please be as specific as possible. Kitchen, Bathroom, flooring is an answer that is probably not the most helpful. What exactly did you do or not do to the kitchen or bathroom? What kind of flooring did you put in and why that vs. something else? Was there something you did as an afterthought that turned out to be a huge selling point? Or a costly expense that was a waste?

Thanks again BPeeps--I am looking forward to your answers....Pics too?
