Used 30x30 Marlin Would Making Repairs To My Lot And Work Building Improve The Value Of The Property?

Would making repairs to my lot and work building improve the value of the property? - used 30x30 marlin

I have a very nice and open about 33 acres. No house is on the lot. I used to have an RV it.the many residential and commercial buildings. Zones unofficial here yet. I work two jobs history of the building on the first floor 30x40, 30x30 second floor.
I thought of a large garage door to replace before sale. At that time the garage door is not the age Operti. It is actually stationary with a gate 8 feet with a door, across the former garage door. It looks nice. What about roof repairs on a 12x40? Do not make no difference in the value of the property at the sale. The lot was once much smaller and manufacture of garden decorations. "I can well imagine, to $ 3500.00 to repair these issues. Thank you for your comment
