For instance if there is a beautiful new kitchen but no permit on record for it, that would not be good for the seller.While it does not automatically mean the work is inferior, it usually is.

Anything with a cap is an inferior service.   

You are bidding based on still owing that amount. depending on the state you need to know what is superior and inferior. think about it this way, you are marrying a person with kids from a prior relationship - those kids do not go away, you are taking them as well.2.
