Yeah, but rent costs go up year after year while your mortgage is locked in at the purchase price. What will SF rents be in 2030? The mortgage payment on your 2013 house purchase might not look so bad in comparison, and often for a lot more space. You can also regain some flexibility by renting out your home and temporarily staying somewhere cheaper. This probably isn't doable if you've got kids, but getting a cheap apartment and AirBnBing your old place might be what you need to do to keep the house without sinking your financial ship. That said, if you're going to start a business while buying a house, better to buy a smaller house and have a working spouse who can carry all/most of the payment for a couple of years. I wouldn't probably wouldn't do it unless I had a reliable high-earning spouse willing to share that responsibility.
