I think various factors have to be taken into account in order to properly answer the question.
Do you own the property (no mortgage, completely paid off) where you will reside in?
What are the property taxes per year in said area? I know of areas in the Northeast that sport $30-$40K in taxes/year, which will eat away at that imaginary $8k/month figure.
Do you own the vehicles you have on site?
Do you have HOA fees?
If all else the same and you have very low monthly costs of living, I think I would do somewhere warm, as close to tropical as possible, with proximity to the water.
