As such, I believe if the agreed fee payment deadline is missed, a landlord could then file a 7-day notice to cure rather than a 30-day notice to quit.

I also recommend giving a 7 day notice to cure, so it is in writing that they need to act appropriately.

Post a notice to cure.

If you do get in, make sure to take pics or video documenting any violations you find and immediately send notice to cure these violations.

I think many people on BP are still doing RE because it gets in your blood and they haven't invented a  cure yet! 

If so, issue the appropriate notice to cure and if they don’t file an unlawful retainer against them for the boyfriend and his +1.

Again, spend the extra money and heat treat to cure the problem quickly.

Check your state laws on the "notice to cure" requirements.If you want to try a different approach, cash for keys works in many situations.

I would probably give him a cure or quit, and if he tries to argue, remind him that a 100% chance of an eviction action on his record + some chance of getting in trouble under state law (Florida has a law against service animal fraud) is gonna hurt way more than a 0% chance of you catching a FHA case.
