Hard to say. All three small houses have been sold like this for a while, and they don't turn up that often like this, so I would consider it to be a more valuable variation of the normal small house. But how much more Not a great amount, I would imagine...
Funny you should mention this....I bought one yesterday for $11 US. I think this was a pretty good price for it though as I know they would probably sell for over $20 US on ebay I would imagine.
