Rent Credits with a Lease Option

Hey DG family, I'm have a question about giving rent credits to a lease option tenant. I know the Don frank act took place at the beginning of this year and permits sellers from giving rent credits to lease option tenants from what I heard. Well, I have an lease option deal I have under contract and looking to put a lease option tenant in it but a couple of people who call to ask questions regarding my ad on Craigslist, they ask me if any money from the rent goes to the purchase price and I say no because of the new law that kicked in. Me telling them no have made potential tenant buyers turn the deal down. I had one lady who had the option fee ready to give me but her attorney told her if I'm not offering rent credits for her not to take the deal. I was confused because I though the attorney would know about the new law. Well, I want to know if they is anyone out there still putting together lease option deal and offering rent credits?
