The balloon is always usually offset a bit. It's the bullseye that marks the location. Also just like using a car GPS, the actual location of street address can be off going up and down a street. Sometime my car GPS says I am in front of my house, when I am actually about 6 houses down from it.

Also if you look on some of the locations the street overlays don't always 100% align with satellite overlay. Sometime there is shifting involved, probably something to do in the mathematics with the conversion between the satellite imagery and the GIS data. All of this is really a function of Google Maps, and how the GIS data gets encoded. I have to take the street addresses and run them thought a script that converts them to Long/Lat for Google Maps to plot. Sometimes those tools and scripts don't resolved to pin point accuracy. Hopefully later the tools will improve to provide better "Front Door" accuracy.
