Ever since the big hedge funds like Blackstone, Empire Residential, American Residential, and Colony Residential started buying "massive" amounts of SFH here in Phoenix (and elsewhere) people have been predicting a crash when these homes are sold.
These are the facts, Blackstone and the others own approximately 13,000 SFH's in Maricopa County, AZ (basically the metro Phoenix area). There are at least 910,000 owner occupied homes in Maricopa County so they own approximately 1.4% of the homes in the county. We have about 30,000 homes on the market at any given time. In addition, nearly all of the homes they bought were smaller, starter type homes which are in very high demand here. I suspect EVEN IF all the hedge funds got together and decided to list their homes at the same time (unlikely) that they would be easily absorbed into the active inventory and sold within 90 days. Plus, there's no evidence that their business model is to make a quick buck by selling. All these homes are rented and shooting off cash flow to these hedge funds.
To date, only a dozen or so of the 13,000 homes have been sold.
AND, to answer the topic of this post, IMO the Phoenix market is extremely stable right now with very few new listings being added and demand starting to pick up from a slow 2014. Definitely no crash here in 2015. I wouldn't pretend to be smart enough to comment on other markets.
