For an individual? Not really, no * . The residential geothermal you refer to is actually not geothermal at all, but more accurately a ground source heat pump which is relying on the fact that the soil temperature a couple meters down is about the average annual air temperature. Actual geothermal-powered applications typically require engineering at depths well beyond the grasp of an individual household, and at costs that almost certainly wouldn't make sense for any reasonable payback period that was only covering household energy consumption. MIT/INL had a nice overview ~10 years ago[1] on enhanced geothermal systems across the USA. Even the commercial power plants that rely on this type of resource are typically situated only in areas with very nice conditions. You also need to be mindful of the heat extraction over the area underground vs. the natural recharge rate. You can draw down the resource if you don't have a good model of recharge, which is particularly problematic for something you probably want to just run constantly once in service. * Obviously, it is possible for there to be exceptions based on extremely fortuitous resource access (in terms of both the heat and personal capital), but for almost everyone this isn't going to be the case.
