text: Upkeep maybe is used more often in connotation with houses or vehicles/physical machines (eg: "the upkeep on this yacht is very expensive"), while maintenance is way more general (maintenance could be done to an operating system on a computer for example, where I would not say "upkeep" on a computer system), but these 2 words are in essence very similar and interchangeable.
