Freddie Mac announced that as of October 29th, changes they have made to the Home Possible program will go into effect. Of these changes, possibly the most beneficial is the change to allow a buyer to utilize Home Possible, regardless of owning other properties. This would allow people to house hack and put a very low down payment on SFH and MFH. See bulletin snippet below directly from Freddie:
