If the serial number on the manufactured home does not match exactly with the serial number listed in your purchase agreement, the easiest thing for you to do is have an amendment to the purchase agreement created clearing up the issue and have the seller sign it. This should take care of the problem you have.Assuming the seller does not sign the amendment (which in most cases the seller will), you could file a declaratory relief action in the court against the seller seeking a court order that the purchase contract be amended to state the correct serial number of the manufactured home. Once you get the court order on the amendment, you can send a ceritified copy of it to your desired lender or any future purchaser.Good question.
