We are in escrow on a single family home right now. The market is crazy with everyone wanting to close by the end of 2012. There are multiple offers on just about everything under $500,000. I'd pull up Zillow and search for sold homes in the last 90 days, then 14 and then 7. The market is rapidly changing with values increasing. So much of the Costa Mesa area is location. PSF and total $ amount really aren't as critical as other things. What you need to decide is where you want to live within Costa Mesa...East side or West side. Do you want to back up to a busy street? Are you comfortable with a neighborhood that has both single family homes and multifamily on the same street. Can the property be financed or do you need to come in with all cash. What are the Homeowner's Association fees? We chose to buy a single family home with a big lot, no homeowner's fees on a street with both single family and multifamily homes. Our price per square foot is higher than the average because the house is only 1300 square feet on a big lot. Certainly cost per square foot is less in a condo, but you have homeowner's fees and typically no yard. So you see that you really have to look at the big picture.
