You can't disclose what you don't know
Most sellers have never sold a home before. Nobody hands them a list of what they need, what expires, what a lender will flag, or what a buyer's solicitor will ask for. They find out at week ten of a transaction, under pressure, when the answer to every question costs time and money they no longer have. The Passport finds it first — quietly, early, when there is still time to do something about it.
