Well that house fell through, due to rising costs and delays, and we've purchased a very different house. A 1930s brick house, original build for US military housing, but the base shut down in the 90s.

In any case the Ubiquiti APs (One Lite, and one In-Wall) are providing solid coverage (5gb available two floor up) from their undignified location of the basement floor. Once we're settled in (we moved yesterday), I plan to properly install these APs plus a second In-Wall unit, and will update with a coverage floor plan then. But this may take a while as things are working so well in this sub-optimal setting.
