Why can't the government simply payoff everyone's mortgage to resolve the housing crisis? 
Could it be done? Yes, it could, subject to local law. A variant of such an approach has been suggested for those countries experiencing collapse of demand. One might consider whether whether it applied to secured loans (such as mortgages), unsecured loans, or both; whether it would be capped at a certain absolute (say £100k) or proportional (first 50%) of each mortgage; whether it would cover first homes only, or all homes; and so on.  These details would radically change the feasibility and consequences of any such intervention. See the related question: https://economics.stackexchange.com/q/146/104 Such a policy of debt cancellation would have several consequences beyond initial stimulation of demand, that would need additional policies to deal with them. Inflation The resultant surge in demand would, in the absence of any other intervention, result in a massive surge in inflation. There are some interesting questions about whether this burst of inflation would be a one-off, or not. One could make an argument that as housing has become much more affordable (at least for home-owners), it would increase the downward pressure on wages, which would be in itself counter-inflationary in the medium-long term. Nevertheless, it would be injecting much more money into the economy than has been seen in QE to date, so the risks would be of extraordinarily high inflation, which might or might not get entrenched. In order to manage the short-term risk, and long-term inflation expectations, it might be necessary to incorporate a lot of tightening, either fiscal (higher taxes and/or lower public spending), or monetary: (higher interest rates, unwinding QE, new requirements for higher core capital for banks) Moral hazard There are risks of moral hazard for individuals: however, as a society, we were prepared to accept the moral hazard for financial institutions and their staff, so that may or may not be an issue: it is likely to be a question of long-term expectations. If the expectation is that this is at most a once-in-a-lifetime occurrence, then the consequential risk from moral hazard ought to be lower. Excess profits to lenders Lenders will typically work on the basis of a certain proportion of defaults, so paying off all loans effectively gives them an artificial boost to their profits. Worsening balance of payments There is to a degree a prisoners' dilemma facing nations here. Pressing the reset-button on personal debt across many of the countries experiencing demand-collapse would benefit all of them. However, if just one such country were to do it alone, they alone would increase domestic demand, resulting in a large increase in imports, but no significant increase in exports.
