Sheila and Karine want to buy an apartment in San Francisco's popular Noe Valley neighborhood. They think their needs are pretty simple: at least one bedroom, laundry, outdoor living space, parking and to be in the heart of Noe. But, in such an expensive real estate market, trying to find a place that has all that and is within their $500,000 budget won't be easy. It's up to their realtor, Danielle Lazier, to set them straight.
