Hey I resent that. Ontario was a great place to buy for me, conveniently located with good services, and it's not hardly as dangerous or Mexican as say Pomona, Fontanna, Rialto, Baldwin Park, Azusa, Compton, or about a hundred other cities in California.
BTW: You would have probably tripled your money if you had, bought a house any any one of the above cities five years ago.
I've just had negative experiences whenever I've been to the "Inland Empire." I simply try to drive as fast as possible from Studio City/Burbank to Palm Springs without stopping. Sometimes, however, you have no choice. ;-)
So...I guess it wouldn't matter if the market dropped 10%, would it?
