I've been adding in many of the houses and buildings in Waverly rather quickly using mapwithai's microsoft buildings data. I've kept corrections on the microsoft buildings data to a minimum in the interest of getting data into osm. Mostly just made major corrections where multiple buildings got merged, buildings overlapped, or building areas were grossly off. If I was reasonably positive the building was a house I marked it as such, but left some buildings that I wasn't sure about as just "buildings". Much of the labeling and geometry of the buildings could be improved upon.
