In my humble opinion only Tim Hensley could answer this best. However, I can tell you that from my quick review of recent transfers it would calculate out to $160/sf. I've seen as high as $250 and as low as $107 for their work. I would highly caution you to utilize that as any gauge for pricing. You need to quantify many things before you can do that.
You should consider whether the lot is included, the fit and finish, as well as overall construction style and or quality. Different finish levels can certainly add cost; arched entry ways, coffered ceilings, kitchen finishings among many other details. Foundation pour, insulation, lighting/electric, plumbing and other structural upgrades should be considered.
I hope this helps, please let me know if I can be of any further assistance. I'm happy to answer any of your questions or give you a second opinion.
Regardless of the quality of the builders work, if you are concerned about the foundation I would have it inspected. Not just a general home inspection, but by by a qualified foundation/structural inspector. Even with a well built home there are things outside the builders control or knowledge and problems could have occured due to the concrete. soil underneath the house, drainage, etc. since the home was built.
Are these homes listed with a Realtor and on the MLS? Since 84% of buyers start their new home search on the internet, it only makes since to work with a Realtor and get those listed online. I know Landen and Kings School district has always been a great area and these homes should sell. Many people are looking for a ranch with a basement. Price is another reason homes are not selling in this market but wait a few months to reduce anymore since the buying season is upon us. I list my homes in both the Dayton and Cincy MLS so if I can help you, please feel free to visit my website and contact me.... more
