Honestly, Shea is a good builder, but Reunion is not a good location. Sorry, it isn't ... Green Valley Ranch (Reunion) started building new homes around 2003 when the market was super hot. Like now, there was huge buyer demand and very low resale inventory. When the market tanked in 2008, just about everyone who bought from a builder is now under water (owe more than the house is worth). Reunion was hit just about harder than anyone.
The other thing no one will tell you about buying a new home is the extra expenses you'll incur after the sale. Things like fences, sprinkler systems, landscaping in backyard; new window coverings throughout the home; MUCH higher taxes regardless of area (at least 1 to 1.5% of purchase price).
Also, beware of signs saying "Starting from the ...." regardless of what's advertised, just wait until you get to the design center. Everyone falls in love with the models (which have every upgrade and more to grab your attention). What a builder really includes is below average.
So, my advice: skip buying a new home and find a knowledgeable realtor who works in the area where you would like to live. Resale is ALWAYS a better value -- let someone else pay for the upgrades and lot premium!
