I can't speak specifically about Oroville - although the SFR market and the Multi-family (apartment) definitely are affected differently. In Santa Clara County, where I work, rents are up, apartment values are up, both in direct contrast to the single family market. This is primarily due to the disappearance of loan programs for first time home buyers. These buyers are shut out of the purchase market due to financing issues and are forced to continue renting. So, in this valley, landlords are very happy and home owners are feeling the pinch.
