Home prices in the San Jose area are going to run you around the 325-375k for a mid level 3 bed 2 bath home on the east side of San Jose. Mid level being around 1200-1900 square feet with an ok yard. If you're looking for a little higher end neighborhood (west SJ) you're going to be starting around 425 for the same size home. The bonus to buying right now is that rates are stupid low and you can buy more home for less money per month... but on the flip side inventory is way down are there are huge bidding wars going on. Check area's like Willow Glen, Evergreen hills or even Santa Clara. All are decent places.
Taxes are a tad bit higher in CA versus NY but you wont have to deal with the dreaded Tax Stamp that comes with buying in NY. Ive seen those go for 10-15k in NY for a similarly priced home depending on what part of NY you're in.
