I have looked over the site and can't find any specifics. I have been waiting for a call back from the mortgage department for about a week and thought maybe I could get some information this way.
I am sorry you have not heard back from someone from mortgage. You can send us an email here at social email@example.com (please include your member number and the type of construction loan you are inquiring about) and we will make sure a mortgage specialist reaches out to you soon.
Here is another discussion that may help provide some additional information.
