If management wants to do this "quickly" they might be better served finding a bank (a larger bank or a bankers bank) that will do this for them (a "private label" type of proposition).
Otherwise, begin to explore origination and servicing software. You CANNOT do the documents that will be in place as of next August 1 without documentation software in my opinion..the forms are dynamic and different language is required or MUST be omitted depending upon the loan. Fees must be alphabetized, very specific abbreviations are required. It frankly is not humanly possible.
You will still need extensive training in the rules so that you understand what is going on, how to classify your bank's fees, what to turn on in the vendor software. I would recommend bringing in a third party to help get the software set up properly given the bank's lack of history with this type of lending.
You can review the CFPB booklets on the current rules and the new rules. I would start there. For the new rules, much is revealed in the preamble. You also might see if you can still purchase the prior BOL Lending Triage materials, and the ones for the Triage that just ended.
Also, I don't recommend trying to do this quickly unless you go the private label route. Even if you hire a LOT of consultants to come in, it will be quite an exercise.
If you go the private label route, the bank still needs expertise because you ultimately retain the risk, even if you can sue the processor. That just gets your money back; you still get the fines and penalties and MRAs and cease and desist orders.
Best of luck.
