> He assumes a 2% increase in rent (no, just no)... and an ROI of 8% on an MMF. Also no. I don't think the example was an MMF - isn't it a whole-market index fund? (The link under that phrase doesn't really clarify, it's just a driver for internal traffic.) Even so, I just checked examples for those, and that class of fund has been earning about 6.5%. That's quite a difference from 8% The 2% rate on rent isn't insane as a national average, but failure to break it down still invalidates large parts of the article. In particular, the P/R section is ruined by that assumption. We're told that at P/R ~15 Owen and Rachel break even, and at P/R >20 Owen loses badly. But high P/R is basically inextricable from rapidly increasing rents. San Francisco, with national-high P/R of 45, has seen 10% average rent increases. Boston, with P/R of 28, has been averaging 4% rent increases. Individual circumstances vary, of course, but the toy example is rendered seriously misleading by overstating market returns while ignoring the fact that rent growth is guided by home price growth.
