I think you've answered your own question.
It's really not practical, and some homes don't have the infrastructure to plug in your car overnight. My last five homes haven't.
Current home: indoor parking garage, there are some outlets, but that's a shared resource and can't be use extensively for one person's car. We actually have a car charging station in our visitors parking, but it's frequently in use, I would not be able to rely upon it being available when I need it.
Last condo: the complex had a parking lot. Each spot had an outlet but those outlets could only be used for block heaters, vacuums, etc. Not for car charging since again, that was a shared resource, each outlet wasn't tied to the electric bill for our individual units. They're working on a solution for this, but it wasn't resolved before I moved, and was the reason I didn't buy an electric car when I was living there.
Apartment before that: I lived on the 3rd floor of an old house. There were outlets outside, but they were connected to the account of the renters on the main floor.
Condo before that: another heated indoor parking garage.
Apartment before that: second floor of a house, same problem as the third floor unit previously.
Condo before that: another complex with a separate parking lot, no outlets at this one
In some regions, laws are coming down that are mandating accomodation for electric cars, but if you are moving jurisdictions, you can't count on this.
If you're not even driving much, I just don't see a significant benefit here.
