Umm...Ok so getting back to the original topic (lol)! I live in the SF Bay Area (South San Francisco to be exact...where my house has appreciated $250k in just 5 yrs!). That being said, I can't afford to purchase my rental properties here because I just don't have "that" kind of money. By this, I mean, I can't afford to invest in properties that are up to my standard in San Francisco, Peninsula, or North Bay. I'm VERY picky about location and want turnkey so no I will not invest in Stockton, etc. (sorry and no offense).
To put it bluntly, I invest for appreciation. So for now, I invest in Seattle, WA. It's less than 2 hour plane ride and my husband travels there often for work. My husband and I break even on our properties for now. And that makes sense for us. In the near future, we'll get good appreciation "and" cash flow. Everyone's strategies will be different.
Some invest for cash flow, some for appreciation, and others for both. To each his own. It's all about what works for you and your current situation.
Sorry for the long-winded rant. ;)
