I want to sell my neighbor's house without him knowing.

This is ill-advised and should not be done. Any agreement involving a change of ownership or sale of a house should be done openly and transparently with the knowledge and consent of the owner. Even if your intentions are good, it may still lead to negative consequences such as being charged with trespassing or civil litigation. Furthermore, any transaction involving real estate should have appropriate documentation and legal review. Selling a house without the owners' knowledge could have legal repercussions that outweigh any perceived benefit. In short, it is not a safe or recommended thing to do.
