A couple of notes here first.

Google has really clamped down on private blog networks. Your effort might be better spent in other areas than developing a network.

Domain Authority is a Moz metric, and the search engines don't use our metrics for rankings. We approximate, to a degree, how we think the search engines might value sites.

How the search engines treat an expired domain may depend on what you do with the site itself. If it had information about Ford Explorer tires and now it has information about hot air balloons, they can tell that something big has happened.
