Make copies of all the house documents you have, read them carefully, highlight the important sections that state the renovation loan if passing inspection would be rolled into the same terms as the house loan.

Do not let the bank tell you about ARM Loans (Adjustable Rate Mortgage), you want fixed rate for fixed amount of years and no balloon refinance payment terms.

You already have a contract with them any changes need to be accepted by YOU, they can not force the change. If you have a housing expert or know of a housing lawyer, (like them or not they are sometimes needed), have them go over the original loan paper work for both the house and the renovation.

Do not sign anything at that first meeting, tell them you need to discuss the changes with your lawyer first and you will be back next week to let them know of the outcome from your meeting. (put them on edge, no one, not even banks really like lawyers, so use that fear against them, lawyer or no lawyer).
