Site Finished Solid Hardwood
Here in Connecticut, there is a strong preference for solid and site finished hardwood. Most homes here have hardwood already, so this is the look customers are accustomed to, especially mid to higher end customers.
Pre-finished hardwood looks more fake here, due to the micro-beveled edges, which often show the underlying color of the original wood underneath. Also, dirt tends to get caught in the edges. When hardwood floors and sanded and refinished on site, the floors are smoothed out and you have the ability to test and customize the stain colors.
