I prefer properties that are heavily focused on the residential component  because mix-use assets receive far less attention than multi-family assets.

However, in the long run, I love the "buy a house a year" strategy (as a primary, for preferred financing) and just keep moving (pending that your spouse is on board with this of course, if you have one).
