There is an old time gas station by my house, they tried to sell it as a house a while back. It fell through for several reasons:
1. Price for what it needed.
The legal stuff it needs
2. gas tanks need to be removed from the ground and the ground abated. They have been in since it closed, pre 1940.
3. The garage for the house, was built half on the house property and half on railroad property behind it.
