Currently, the property we are interested in is using oil for heat. The house already has gas line hookups close to the boiler but not connected. I am wondering how much approx would it be to convert oil to gas for heat. This is an above ground tank, which will be removed.
PS, I also found this thread regarding Oil heat conversion: https://www.biggerpockets.com/forums/67/topics/598222-conversion-of-the-heating-system-from-oil-to-gas
