Question healthy market or less than healthy?

[Mike Darling]

when looking for the best area to start buying homes for fix and flip is it best to look for areas that have a healthy market or ones that do not? I have looked at a lot of my local areas. I looked up on zillow the market health index for a specific ZIP Code and in most areas it is not very healthy for instance a 2.8 out of 10 should I look in healthier areas for a better area to invest in to get started? There appears to be deals in the less than healthy market areas and according to one realtors sold comps the average days on market after all repairs are done is under 90 days.
