See not only how much it sold for, but what exactly was sold
"I can check the archival price - that is one thing, but what offer stood behind that price is another. That is what gives an edge."
We attach the archived listing to the notarial transaction price: photos, description, condition and year of construction. You show the client the standard of the comparable property that sold - not just a dry number.
