An investor-driven recovery -- What does it mean?

[John M.]

I saw this article on metanews and it went into how what we're seeing as a potential recovery in housing isn't an organic recovery, it's an investor funded recovery.
They said because the return on investment is better in rentals than anywhere else right now, housing is recovering from cash investors, not from home owners.

My question, assuming this is true, is what does it mean in 5-10 years?
And assuming there's an end to the investor money, what then?
