Lee, I believe I now understand your intent of your original post. It was to ask people to speak with brokers and determine if there was a way to use 223f financing to achieve 100% financing. And then to report back on what they had found so we could compile a list of the situations and parameters where 100% financing using this program was possible.
Your first sentenance, though:
In some circumstances HUD 223F is able to do 100% financing.
very much sounds like you are stating that 100% financing is possible, and leads the reader to believe you know how to do this. When I first read this post, the first sentenance led me to the mental assumption that you did know how to do this, and were going to tell us. Reading the rest of the post just left me confused. The message I took from the rest of the post was "go to your brokers with your deals and they will be able to make this work for you, too."
Since we're discussing how this went off the rails, let me suggest that a first sentenance like:
I have been led to understand that in some circumstances it is possible to use HUD 223F to do 100% financing. Has anyone seen any evidence this is true.
That makes it clear you're asking a question about this, not a statement.
This is a forum, not a wiki. Posters here make statements, then others react to them. On a wiki, which I have used extensively, the goal is different. It is to work collaboratively to produce a final product that reflects everyone's knowledge and that factually covers a topic. Even on a wiki, throwing out something as a statement when its really a question can lead to misunderstanding and confusion.
So, assuming the question really "Is it possible to achieve 100% financing with 223f financing?", we can continue the discussion from there. So far the responses seem to be no, that's not possible under any circumstances.
