Yes, this might have had in impact on the Trumps' decision.
Reportedly it will to be a very serious, heavy-duty renovation. I wonder if there are other areas of the WH that will also be disturbed that we're not hearing about.
When Truman ordered the WH gutted in the '50s, allegedly for installation of modern wiring, better security etc, the Truman family lived in Blair House for quite a long time, I believe.
The Bush family had quite a big mess to clean up after the Clintons moved out also, especially the West Wing where the offices are!
