I believe it is mostly a pet name given to underwater home “owners” that so kindly referred to the bubble blog participants as JBR’s or jealous bitter renters.
You will be hard pressed to find any sympathy for your position on this blog. The whole idea behind Rich’s site is that when he started looking to buy, the data suggested homes were over priced. Discussions of data turned to them vs. us, i.e., FB’s vs JBR’s. Funny you don’t hear the endearing JBR term anymore. Unfortunately you represent everything that led to unsustainable price increases … $0 down, interest only, no feasible way to actually pay for your home without massive appreciation or lottery win.
Wrt your current position, from a purely financial aspect you should have left a long time ago. Looking at home price indices, price trends, ARM reset chart, foreclosure levels and trend … it doesn’t appear prices will rise again anytime soon. At best, they will level off (doubtful) and have no appreciation for an extended period of time. You have no skin in the game, stop paying now, get your finances in order and find a rental you like since you won’t get another mortgage for many years.
Don’t mean to sound harsh but try to be realistic about your situation.
