As an interim solution, the property owner might be able to install large batteries (for example Powerwall) that renters could use to charge their vehicles. The batteries could be charged continuously, without overloading the old electrical service Probably this wouldn't be enough if every renter was a heavy EV user, but it could be good for a few years, and also would be useful for power outages and to take advantage of off-peak rates in future Metering and payment would be an issue, but it should be possible to find a solution for that
