NEED HELP! Need 1 extra bedroom

[Edgar Cienfuegos]

So i have a question, I am looking to buy a house currently that is 2bed 1 bad (1,386Sqft) but it has a seperate "living room" where the carport was originally , Making that into a room would significantly help with the sale of the house. Any advice on how to make it a legal room.

Location: MACON GA

Note:it does sit 2 steps lower then the rest of the house and it does have A/C , The front has a sliding door facing the driveway
