only if he bought that software and equipment especially for this work.
No he had the software to do some virtual home decorating! You buy 3D animating software to do this kind of work, most likely he used post-processing software and editing software.
Hardware: he had no strict schedule so no need for lots of processing power, low resolution also decreases the amount of processing power needed per frame. This does not fly in a commercial hollywood production with a strict schedule. It's not a one on one comparison.
Actors: friends, art-school students etc. no need to pay them or provide lodgings, food etc.
Outdoor footage, often cheaper. Inside you need gaffers, screens, etc etc etc.
There's so much more to a big production, in terms of logistics. A small production like this is always much much cheaper because it doesn't have the huge overhead of all kinds of support staff ( and an expensive cast).
