You tag even/odd/... on the interpolation-way, not on the street.
If you have to resort to interpolation you make a way between
a first house and a last house and tag that way with how the
interpolation is to be done and optionally what street this is for.

Only if every house and intermediate street and garden around the
house  has the exact same exact size.

And when someone else comes around to add the missing
building-polygons with the shapes of every single house it
gets obsolete anyway.
Interpolation is just a usable way to tag many long streets with
lots of houses in a sensible timeframe.
