This  10,000 sf building on 9 acres would seem over priced if we were comparing apples to apples.  

@Adam Widdicombe  just to set the record straight  I started turn key reviews to give the public a place to rate the operators so that if there were some bad apples like you talk about they could be found out.TK reviews is basically a public service site.. there is no money being taken other than tiny revenue to keep the site up and running.I could care less were people buy their homes.. but since TK is a thing and has been for 2 decades we might as well talk about it and take the mystery out of it.I am a fairly active new home builder doing about 20 million a year in new builds

Make sure you are looking apples to apples. 

Upsetting his apple cart will quite possible do the same to yours.

You want to compare apples to apples, so if in the subject property each side has 2 bedrooms, 2 baths you want to use comps where the other duplexes each have 2/2 each side.
