Real estate startup ZeroDown will help you buy a house in San Francisco with no down payment

It’s fairly well known at this point that San Francisco is one of the country’s (if not the world’s) craziest housing markets. Houses there are incredibly expensive, and only getting more so. Heck, even ramshackle San Francisco shacks are listed for $2.5 million. But, now, there’s a way for people to buy a house in San Francisco for as much as $1.75 million with no down payment.
