Potential buyers who like sheds will like it. Potential buyers who
don't like shed will not like it. You never know.
I recently sold my house. It had a shed and a steep driveway. Some
people didn't like the driveway and never looked at the house. Some
didn't care about the driveway, but didn't like the shed. Someone
thought both were fine and bought the house.
Six months out from selling, I would spend $3200 on making anything
that looks dirty clean again. That's the best way to appeal to
everyone looking.
