Hello, Stephen and welcome back to Just Answer!My name is XXXXX XXXXX it will be my pleasure to assist you today.If you can place a second door on the other side of the house, your best Feng Shui direction, and the cost of construction isn't a problem for you, then that would be the best solution. The second door overlooking the back yard is fine, if you don't mind walking around to the back of the house to enter. However, make sure that the current front door and the new front door are not directly opposite each other, as this would not be good Feng Shui.If you are keeping the original front door but you would never use it yourself, it will not pose a new problem, because you will have designated the new front door as the one overlooking the back yard.
I forgot to add that I have not actualy purchased this house, and that there is extensive damage to the interior! Is it better to not buy it in the first place?
