Hello Mary and thanks for your post.
Although I'm not familiar with KB Homes, the Quarry at Iron Mountain, my husband and I once owned a KB Homes condominium here in San Jose. At least here in Northern California, KB Homes properties were often subject to construction litigation due to problems that developed at the homes. Although our townhouse style condominium did not have any major problems, many homes in our condo complex developed problems and, ultimately, even our complex filed suit against KB. In all, I was not as impressed with their overall product as I was with other developers.
If you choose to purchase a home--even a brand new home--have the property inspected by a qualified new homes inspector. You will not regret the money or the time it will take to do a thorough inspection of the property. I would also suggest, especially if other product is being built, that you take the time to watch how the building is constructed and have your inspector make periodic inspections of the property while the building's "skeleton" (frame) is exposed. I'd like to think that the quality of KB's homes has improved over the years, but our first new home buying experience taught us to be cautious and not to assume that the product is good simply because we fell in love with the models.
Good luck on your home hunt and purchase!!
