Cathleen and Andrew have made offers on multiple homes, without any luck, and with their lease about to expire, they're running out of time to find a place near Northern California's wine country. While Andrew prefers the Marin County city of Novato, where he works at his family's lumber mill, Cathleen wants to buy about 15 minutes north in quaint Petaluma, where the homes are more affordable, but some sit on "adobe soil", which can shift over time. With $450,000 to spend, will they stretch their budget in Novato, or will they be desperate enough to buy a home that could be moving right under their feet?
