@Account Closed You're looking for houses that will cash flow in San Diego with I'm assuming a low down payment after 10 years of wild appreciation in one of the most desirable places to live in America...
Your head is in the right place, but maybe we need to temper expectations first. As an example, let's say your options to rent are going to cost you around $1,000 a month for a room and another $200 a month for any various utilities.
If you "house hack" and get your living expenses down to $200 a month total, you will be saving $1,000 a month. $12k a year cash. That's a huge return. Sure you aren't technically cash flowing, but your finances are in a much better position than renting.
Me personally: what I would do is find a 5 bed house in a nice area where the seller is willing to do some sort of seller financing. Furnish the rooms and then rent by the room. $750 a room total gets you to $3k a month cash. That would probably cash flow or break even at the worst. I have a house hack in Vegas that cash flows around $1,200-$1,400 a month after all my living expenses are covered. It's a great way to get started in this game.
