Hi Gpsma,
I do hope you are able to find a home that is just right for you!
Although non-negotiable new home prices might be unusual, there is a silver lining. At least you can rest assured that you would not have paid a lower price, if only you had held out.
I bet there's a home with your name on it here, and I hope you find it and live happily ever after. Please keep us posted, ok?
