Nick,
    My data set contain  sales price of a property (house) in a particular
county between the years of 1977 and 2007. The county is the same but there
are 11 different communities within that county. Within a community there
are more than one house that were sold in a particular year so when I use
community as my id I get the error message as "time values repeated within
panel".To me it looks like a unbalanced panel. 

How should I treat this kind of dataset????

Basically, same county, different communities, different houses sold between
1977 and 2002. Some houses might be sold twice between 1977 and 2002.

Thank You
Ajita
