For players who have entered their estate at least once during the suspension period:

The auto-demolition timer will be reset after the release of Patch 6.3 for free company estates that have been entered by a leader or member at least once, and private estates that have been entered by the owner at least once.

The count for days of inactivity for the aforementioned estates will begin again with the release of Patch 6.3.
More houses incoming after 45 days have passed since 6.3 launch. They will auto-demolish on February 24 and we should be able to bid on them in the cycle March 1 - March 6.
