>> the declining interest rates that fueled past appreciation don't have much room left to move down, and that they'll be underwater on that huge loan if interest rates go up* and the value of the property declines.
The price you can charge for something is related to how much other people can pay for it. If houses are usually bought with loans (which they are), then the availability of loan funding is a major influence on the price of a house. When funding is plentiful -- another way to say this is that interest rates are low -- the price of a house will be high. When funding is hard to find -- or interest rates are high -- the price of a house must drop to compensate for that.

I am not very optimistic on homeowners in a downturn, UNLESS the government bails them out.
There are some other options out there for veterans or first time buyers, but those are the normal options.
