In further testing, there's actually a bug here.

If I specify the property name in the projection, I don't get the null 
properties back.  e.g. SELECT @rid, Street1, Street2, City, State, Postal 
FROM Address WHERE (@rid=#14:1) will omit Street2 from the response if it 
is null.

If use wildcard, then I get the null properties back.  e.g. SELECT FROM 
Address WHERE (@rid = #14:1)
