Finding a Real Estate Matrix

Is there a Real Estate Matrix that I can refer to, to see if I have all that I need in regards to compliance? Example: I have a Consumer Real Estate loan and it is a renewal with no new money. Purpose of Loan my worksheet says Renewal orginial purpose (0602) was to purchase and improve residence. temporary financing. So do I need a new application, collect HMDA, Good faith? This is where I am getting confused. We make a lot of Commerical Real Estate loans and some consumer R.E loans. My confusion comes in when we renew. So is there a tool out there that I can refer to to help me make the right decisions when it comes to exceptions?
