My understanding is that in the first few months of the Trump administration, there was a significant increase in the cost estimate for the Wall (up to $20-25 billion), and that increased budget for buying land was one of the drivers.
There was discussion back then to ensure that the lessons learned from the Bush-era land condemnations (takings) were addressed.
We will probably see how this round is shaping up over the next few weeks.
We can only hope it gets resolved soon and under way.
