The only time I see "selling to buy" as a viable strategy is if there is some degree of certainty that my sell property is going to suffer some type of economic set back, and my buy properties are going to return at least as much cash flow to me (including the recovery of sale costs and loss of cash flow from that asset) , appreciate at the same rate or above as the asset I sold and the by assets are NOT going to be exposed to the same degree of potential economic set back as the sell property. 

What most don't, realize, remember or know is that Denver was one of the 1st markets in the country to get hit in 2007 - so it is one of the 1st and strongest in the recovery.

as we say here... recovery.  

If you're going to invest here I'd suggest you concentrate on areas you know particularly areas which are lagging the re recovery.  

All great athletics have coaches, but not all coaches are athletics.

YOU need to cut yourself off from the drug and start your recovery.

While you wait for the market recovery, enjoy the positive cash flow.

There is no such thing as a successful professional athlete who doesn't have at least 1 good to amazing coach.

Recovery from a market shift is a slow process and many may be forced to sell prior to a return to break even.Many plan for long term hold however life will often get in the way.

As many have voiced - you have minimal chance of recovery from the Builder, due to expiration of Builder and Structural Warranties , compounded by the fact property was also an "As Is" Foreclosure.
