On a trip from D.C. to California's wine country a few years ago, Keith and Rob discovered how much they love the place. So much so that they decided to move to San Francisco permanently just so they could continue spending their days off strolling the vineyards and tasting wine. Now they're putting the next phase of their plan into action--buy a tiny home there. That is, if they can afford it. Tiny or not, real estate with wine country views can get pricey.
