Smart investors evaluate both cash flow AND appreciation. In Portland, the 2.78% cap rate provides modest ongoing cash flow, while 3.2% annual appreciation adds an equity component. Conservative underwriting is essential. Focus on deals where the cash flow stands on its own, and treat any appreciation as a bonus.
