Not only is MacGyver an international man of mystery, but he's also a sound investor. MacGyver has residences all over the world (and by world I mean Vancouver, British Columbia). MacGyver has several pads that just scream successful bachelor.
Here are some photos of his Observatory Pad, Condo Pad, Loft Pads, and Houseboat Pad.
As you can see, MacGyver's only vice seems to be compulsive spending on lavish real estate. As a super secret agent, however, it's just part of the job to stay on the move.
