There is no "Popular Guru" teaching lease-option to buy programs where the transactions will be compliant as intended meeting new accounting requirements (by everyone in business) and/or the IRS Code, they don't event touch the subject matter I'd bet on it. 

You won't be able to pull the necessary permits unless the zoning is compliant with the current code.

I said initially as loans must also be compliant with federal laws.

HUD-1 forms were not formerly required to close cash sales, and TRID documents are not required to close cash sales now, although either the HUD-1 or the TRID forms can be used if the parties so desire.In my own real estate businesses, I regularly have some transactions that must be TRID compliant and others that are exempt from TRID.

Your RMLO to be compliant in underwriting and processing a financing arrangement must verify income, employment, debts, credit and other matters just as if the buyer were obtaining a conventional loan.

Owner financing using an interest bearing loan can only be done for one home per year to be compliant with Dodd Frank and SAFE Act laws.  

You might also check on the SAFE Act and Dodd-Frank requirements if you are living in that property because giving credit under a contract to the purchase price is a financing contract, regulated by those federal laws and if your seller is not exempt, you may have won a free house or at least. all your money back as rent-to-own stuff is usually not compliant. 

Settlement agents may still be used by lenders in providing the Closing Disclosure if the settlement agents are compliant with the Final Rule’s requirements for the Closing Disclosure.How can you prepare?

Got all that taken care of and now I have to find out if I have to register the property with some local entity to be compliant with their rules.
