In general it is a form of a construction loan, at least if I understand what you are talking about. When you say remodeling you are talking I don't like the kitchen, what you are talking about is the kitchen is unlivable.
What you have to do is show how much it will cost for the work and how much the home will be worth when it is done. So pretty much if you are paying cash for the home then you need someone to appraise the homes value when completed. You need to have contracts for what they work will cost. Then you can apply for the loan.
I am not sure if I worded that right but my brain shut down an hour ago.
