House Hack Detached Garage in Florida

[Tyler Lukey]

I am looking for property in Lake Worth, Florida. There are a large number of houses here that have in-law suites (guest houses, cottages, etc.) behind them. I am trying to crunch numbers to house hack and found a few houses that are 3/2 that have detached garages behind them. How much on average would it be to convert a 400sqft garage to a livable room with a small kitchen and full bathroom? In this case, I would rent the main house and live in the "tiny home."

Thanks
