SFH vs Apartment cash flows

[Mat Daussan]

Hi all,
I recently read the following article about how the US government is planning to market a ton of foreclosed homes as rentals and noticed the following comment in the article:
"Single-family home rentals can yield cash flows that are 300 basis points, or 3 percentage points, higher than apartments"

What are everyone's thoughts on this? Is this true in your experience in real estate? I've been under the impression that multi family units normally cash flow better than SFH units.

Here is the article: http://www.bloomberg.com/news/2012-01-31/foreclosures-draw-private-equity-as-u-s-selling-200-000-homes-mortgages.html

Any other thoughts on the article would be great as well
