In most times, I would certainly suggest renting for a year before buying. But 2020 and 2021 are not normal years with Florida home prices heading up substantially. In this market, time is of the essence.
I was talking to my close friend last week who's a realtor in Ft. Myers. He sold $10 million in homes last year, and he wasn't even working that hard. A 2 bedroom (small) condo in a 4 story beachfront building is running $550K. He cannot get over the increase in prices.
I would suggest you identify where you want to live, and start looking online. If you don't know where to move, look to City-Data.com for great suggestions if you give them what you're looking for.
Florida is 832 miles from Pensacola to Key West, and there is big differences region to region within the state. If winter temperatures are your biggest concern, look south of Orlando and Tampa. The Panhandle is a completely different place with lower home prices--but it's a little cooler in winter.
I've traveled the state extensively, and I like the Atlantic side from St. Augustine down to Cocoa very much. An alternative is LA--Lower Alabama where home prices are cheap and property taxes are ridiculously cheap. No AL income taxes on defined pensions or social security either.
