There's a lot of basic financial "tools" one can use when looking at whether you should treat your home as an investment bank, arbitraging interest rate spreads or investing in other opportunities. The gravity of the risk and the probability of harm should be balanced against the "gain" one can have on the upside, when you turn your home into an investment house.
One can agree that being house rich and cash poor is not an enviable position to be in as well, but on balance there are many more things you have to consider (emotional as well as financial) which might tip the scale of being "stuck" with an illiquid asset (which can be monetized by a reverse mortgage after 62 and beyond) and not making a better return on your home. Indeed, taking into account creditor-debtor protection for jointly owned residential property by spouses, and favorable estate and Medicaid-long term health care planning -- the balance might actually tip in favor of having the illiquid asset of a house rather than leveraging it into better returns (and even safer ones too) from investments.
