Yes the probability of hitting a house is low. To begin with assuming uniform sampling over the planet (asterisk here) hitting land is lower than hitting an ocean / large water body. The asterisk here is that from my knowledge asteroid belts in the system are almost co-planar to Earth so even accounting for dispersion my expectation is that the dostribution to the Earth surface hits is not quite uniform.
