That's fair - but that is assuming indefinite long-term deflation. What about intermittent modest deflation as a tool to bring prices down? It seems that just the idea of deflation is immediately rejected in any conversation about monetary policy.
Also, I think in the real world today, a home would still sell in a deflationary environment, given serious supply shortages. Especially for those buyers which are looking for a home and not an investment (investors would lose long term in a deflationary environment, as you say). Couldn't temporary, modest deflation actually open the housing market up for those "real" buyers primarily looking for a place to live?
