What actually moves the needle
In rough order of impact per dollar: paint, the front door, the garage door, exterior lighting, and the walkway. Shutters and trim details matter less than people expect; proportion and colour matter more.
Florida particulars
Colour behaves differently under this light: a shade chosen from a chip indoors reads several tones brighter on a sunlit elevation. Sample on the actual wall and look at it at midday. Landscaping should not touch the stucco, because plants against a wall hold moisture and invite termites.
What a curb appeal remodel is worth
More than its cost, and unusually reliably, because it is the only remodel every visitor and every valuation sees. It is also the cheapest to get wrong: colour chosen from a chip indoors reads several tones brighter on a sunlit Florida elevation, and a front door slightly out of proportion for its opening is the detail that makes a new one look wrong. Sample on the actual wall, at midday.
Do it in one pass
Painting now and replacing the door in a year means masking and touching up work you already paid for. Sequenced together it costs less and the result reads as deliberate.
