My point was that it is a public record and someone could go to the local municipal office and look up who owns the place, purchase price, etc. Maybe such info is available on line too.
All of the information is online.
Go to the link for "District of Columbia: Real Property Assessment Search", and enter "Square 0273, Lot 2128".
Huma Abedin is listed as the sole owner of the condo.
The sale took place on September 18, 2006.
The sale price was $649,000.
