I had a listing that was a great home, but when you looked at it, the front door just did not fit.
This door just clashed with almost everything. It also did not fit tight and people made comment of that.
A new white door installed for less than $175 and it looked much better. The first people looked at it wrote an offer. Although my seller did not take the offer, the agent who had shown the house before said the door made a world of difference.
You don't always have to spend thousands, many times it may take a couple of hundred to make the extra few thousand!
