Being near family is important and I think worth more than anything else. I think starting in Miami will turn you right off of Florida. If I were ever to want to be in Florida I would pick Cocoa Beach, Melbourne area if that is in the area that your family is choosing, it is peaceful in that area compared to other areas I’ve been to. Orlando area is crazy for traffic. If you think you would ever want to return to CA and you sell, going back may out price you so I’d keep the house but if you think you will be moving and that’s it, sell it and use the money for your new abode. Whatever your choice enjoy the journey.
