Forgive me for asking an ignorant question, but does this mean it will be easier for them to keep their buildings and property?
I am not sure. It would be a good idea to verify when exactly the Church in the United States was actually formed. Remember? They had to ask England for a bishop. Prior to the Revolution, the Church was overseen from England and visiting bishops were sent from there to tend the flock in the new world. Subsequent to the Revolution, the appointment of a bishop from England became an impossibility. The solution was to seek a bishop from Scotland instead (as recommended by the Church of England) Bishop Seabury was sent to the United States to be its first Episcopal bishop
(From Wikipedia)
The Scottish Episcopal Church enabled the creation of the Episcopal Church in the United States of America after the American Revolution, by consecrating in Aberdeen the first American bishop, Samuel Seabury, who had been refused consecration by bishops in England, due to his inability to take the oath of allegiance to the English crown prescribed in the Order for the Consecration of Bishops. The polity and ecclesiology of the Scottish and American churches, as well as their daughter churches, thus tends to be distinct from those spawned by the English church - reflected, for example, in their looser conception of provincial government, and their leadership by a presiding bishop or primus rather than by a metropolitan or archbishop. The names of the Scottish and American churches inspire the customary term Episcopalian for an Anglican; the term being used in these and other parts of the world.

The establishment of both churches pre-dates the creation of TEC and the Diocese of Virginia--they were charted under the Church of England while Virginia was still a royal colony.
It's debatable.
