If he wants rental property though, it's almost a sure bet since rent is ridiculous in most areas. Almost certainly enough to cover a mortgage.
Is it really? I rented by the beach on a regular basis. Two blocks from the beach in Marina Del Rey was going for about $2400 a month for a 3 bed room giant place when I was there. You couldn't buy even remotely close to that.
You really have to look at rents and if you can profit from this. If you have to dump $50,000 in the property to get rid of 70's shag carpet and wood paneled living rooms plus inevitably a new kitchen then it's hard to make money on these places as rental properties.
Want to get in on one of the areas that only had a minor correction? Sure go for it. Hit up Beverly Hills, Beverly wood, Cheviot Hills, and that whole area for $1,500,000 and see if you can make a profit on rent. It's not easy. If you want to try to buy a duplex or something in that area it will probably be in a somewhat less desirable area and it will still cost you a boat load of money.
Maybe try San Diego. I haven't looked down there in a long time but maybe they have it better.
