Keep pressing on him to rent… Invite him over to a bbq to your house then just happen to show him a computer that happens to be logged on to this site…
Otherwise I like some of the older homes in La Costa Valley… Perhaps something in Solana Beach? I am not overly thrilled with Olivenhain. I do like the Elfin Forest recommendation but is that the lifestyle he will like?
What is important to him? Coastal proximity? School districts?
