Thank you, Kevin
I assume that means that the living area is below grade, also. That is kitchen, dining, and living are all below grade.
Guessing, this is unusual for your market, but there must be others that have things upside down, too. And that is what I would look for, other functionally, unusual floor plans.
You say it is being purchased at below market. Is that because its condition is below market, or is this floor plan the problem? If it is the floor plan, it may not be selling below market. If the living areas are in a basement, it may make it difficult to sell at typical market prices, under any situation.
Most houses in this area have basements, but the living areas are not down there and the market would not be kind to that type of situation.
