Okay... Now I totally didn't expect this to happen. Within the last few weeks I sold the house (173 Blackford Castle) that my character Amgine had owned using the in-game option to put it back on the market. Tonight, out of curiosity I checked the availability of the house with the Housing Vendor in Leringard and saw that it was available. I went through the purchase dialogues, expecting to be told I didn't have the funds to buy the home, but instead it was sold to me for exactly nothing. Not a single True.
I guess you could say Emwonk found the house abandoned and became a squatter!
Obviously this is a bug. When someone can get around to it, please fix it so that the house goes back on the market at it's proper pricing (which I believe was originally 65,000 True before Amgine made his own renovations to the home).
Even though I don't play here much at all anymore, I still don't wish to be banned for exploiting the system or anything, which is of course why I'm posting here about what happened. Honesty is the best policy, even if Emwonk wouldn't agree from an in-character point of view.
