If you are moving to an area like where I live … ie no mains sewage, no mains gas etc… do check if oil heating and hot water, state of the oil tank. If it’s relatively modern, it will be plastic and be sound… if older it is likely steel and could be in a rough way…. and can be a bit lumpy on finances to replace if not expecting.
Good thing though domestic heating oil has been cheaper than gas sometimes massively so in recent years.
The other thing to check is the mains fuse and utility feed… ideally you want it rated at 100 amps, and if overhead feed, there is a good chance it will be … what with all our electric car chargers will be needing over the next 10 years or so.
