I'd be cautious about a house left vacant for 6 years.
Most likely the heat/ac was not running that whole time.
Without ac/heat, there might be moisture/mold issues.
Check the crawl spaces/attic/basement (it's good you found the termites so it can be fixed before purchase is final).
Be sure to look for signs of flooding/watermarks, etc.
Does it have any Chinese drywall in it? (You'll know by the smell, and check electrical wiring for signs of corrosion).
The plumbing (incoming/outgoing), septic system, well (if any), the wiring, roof, etc all should be checked out.
Also (it seems basic but it saves a WORLD of problems if you do it up front) a lot survey - know where your property lines are!
It saves with arguing with the neighbors about who owns what (and who mows what) and where you can put fencing for kids/dogs, etc.
New houses don't have maintenance/replacement problems like some older properties do, BUT new houses can have issues where some things were not installed properly (vents/duct-work/insulation/etc), and mostly likely any builder warranty the property might have had with it's first owner was over within a year or two (4-5 years ago).
It could be everything will be perfectly fine!
I tend to be on the cautious side, but that's just me.
