My fiance and I have been looking online via Redfin, Zillo, Landwatch, Land & Farm, Mojave Realtor, and a few others. Some of the lands that are for sale show up on all the same sites, so we're wondering if we should simply buy the land through a real estate agent or directly from the seller (via Craigslist, for example)? We will only be able to fly out to California from the East Coast one time to view the land & make the deal. We also need to be able to camp on the land while we build; off-grid is okay but we'll need access to water even if via well because we have pets. We're looking in San Bernadino, Kern, and San Luis Obispo counties. Thank you for your time and advice.
