Flipping the houses in France?

I recently hit my fi # . My wife has EU citizenship and we have been planning to move to France for the past 8 years. Both kids are getting graduate degrees in the NL and will likely stay over there.

Though we can draw down from our investments I still would like to generate income. I'm a home builder, hands on, and was thinking of buying / living/ renovating homes and reselling. ( Surprisingly my wife is onboard) I would imagine to live there for 2 to 3 years and move on. From what I've been able to gather, seems flipping is not encouraged by the government . I would frame what I intend to do as creating a more sustainable home by adding solar panels/insulation and heat pumps but I understand the negative connotations..

Does anyone have any opinions regarding this plan?
