You asked this same question in Feb. 2009, stating you didn't think you could afford the expenses (property tax, hazard ins., upkeep, etc) Well you've made it another almost 21mos.
Your property value has most likely declined further since Feb. 2009. You could get a home equity loan, like you were looking into back then, yes there will be fees to do that, but you also have to be able to afford the payments.
There are still a lot of homeowners in Montebello that are defaulting on their loans, causing foreclosures & more properties will still decline in value. If you don't think you can hold onto this house for another 5-10yrs, you should sell now.
Or else you're going to be back on Trulia again in a year asking if you should sell, and I'm going to be telling you that you should have sold a year ago when values were higher.
Let me know if I can help, I can let you know what your home is worth Now.
