My house has such language in an old deed. How do I know? When I bought the 1910 house, I did the deed research and traced the property all the way back as far as I could go. Who else besides me (or a similar weirdo) would even do that?
Of all the things I have to spend my money on, all the things I need to spend my money on, not to mention things I want to spend my money on… I’ll let this one go.
