Your Welcome! I hope you're able to find a great deal in Costa Mesa. Again, it's important to drive the area & figure out which neighborhoods you like the best, you should also check just over the border into South Huntington Beach, there are many more neighborhoods over there that are much like the Costa Mesa side.
If you find a particular area you like but aren't finding enough homes on the market that look like they'll work for you, just let me know. It may just require my digging around a bit, there's likely homeowners who are terribly upside down & you could get a great deal on a short sale/pre-foreclosure property.
