Value add or mistaken calculation

[Todd Finger]

Considering turning our garage into a 4th bedroom. Which would turn our now 3/2 at 1840 sq. ft. with a 2 stall garage into a 4/2 at 2000 sq. ft. with no garage or car port. At the same time, putting a large storage shed in back to hold what the garage would have. Only been in Florida 2 yrs. and don't know how important having a garage is to Florida Real Estate. Any advice would be appreciated. Thank you.
