Disagree with his last point here:<p><i>(One thing this illustrates is that the downside risk of owning is much higher than with renting.)</i><p>Financial risk, yes; health risk, no.  Only a homeowner who <i>owns and lives</i> in the dwelling would care enough to follow the proper procedure for cleaning up a hazardous materials spill such as this.<p>Landlords who invest in buildings (old, decrepit buildings) for the renters&#x27; income have almost zero incentive to handle a situation like this correctly.
