I own a 2 car, detached garage with space above it that could be turned into an apartment (ADU) behind my home.
It has access to water and electricity.
I tried putting it on neighbor.com and got a request the second day it was up from some guy that I got weird vibes from when he visited so I deleted the listing lol. Claimed he wanted to store boxes and I think a car.
I’m never going to use the space for anything at this point in my life.
I need some ideas on how to make some dollars from it.
I would go ADU or if you live in a desirable area then list it on AirBNB.
BUT, your biggest issue is going to be converting it into a livable unit and adding a sewer line if one is not already there. You could convert it to a studio which would save you some renovation cost but will also lower your rental rates.
I would get quotes to finish the apartment. Then you could split the garage with the unit so you keep 1 space for yourself to either use for storage or parking or whatever and the other space goes with the rental. The ADU will also increase your overall property value.
