Also...even though in 2020 this would REALLY be a stretch. If the house was built between 1945 and 1955, there is a possibility that the house is wired using aluminum wires instead of copper. This was done during this time because of a lack of copper; it was all used in the war effort. Aluminum isn't as good a conductor as copper, and overheats easily when current is run through it. Now, by now most if not all of those homes will have had the aluminum wires striped out and replaced with copper, or the aluminum wires were abandoned in place (and taken off the power grid) with copper wires installed in similar locations. But there may still be a few aluminum wired houses still out there. You will have to ask the seller about that and/or when the building inspector comes to do the inspection, make sure he checks to see how the house is wired. (BTW a house inspection is required, and you have to pay for that. That's another cost that you will incur when buying a house that I don't think was mentioned in another post above).
