Newbie question about buying half of a duplex

[Clint Barrett]

Hi,  I've been reading a ton about buy and hold and just recently found Biggerpockets.   I have found what I think would be a great cashflow rental, but it is half of a duplex.  I'm wondering if there are any legalities, special insurance, or any other potential issues I should look out for when buying a property that is physically attached to another.

The property in question is a 900sf 3/2 listed at 69k, and I think it could rent for $850-900.  Seem to be in pretty good shape.

Thanks for your input!
