Ending the Enabling

My DH was diagnosed 2 years ago at age 42, is on Adderrall with good results overall.  We have been together 20 years and have a good partnership-best friendship based marriage with fairly good communication.  The issue is that I realize I am enabling him at a plateau in his improvement and I now am the only income for the entire family - and it is not enough to support us on the basics.  We are living in a house that is in my father's name - we moved in when the 10yo was only 2months old, intending to buy the house & had some money in the bank.  My husband had been in real estate for 10 years and did fairly well at it, until the last few years and his follow-through was lacking more and more.  He did "just enough" consulting and photography "gigs" through the years around the diagnosis to bring pocket money in, and sometimes it seemed he might develop steady income again.  He of course knows the steps he needs to take to get a job, understands to break the task into smaller tasks and accomplish those to meet the larger goal....  the issue is he is now basically a stay-at-home-dad and finds home repairs, etc to redirect himself away from the non-fun task of job hunting.  He has been to a few job fairs, etc but has not submitted resumes.  I want to be out of this house by the end of the year - or to have been able to buy it off my father so that he will be able to retire.  Without income from my husband, we will have to move our family of 4 into an in-law suite as that is all I can afford.  My ADD husband is a pack-rat and our full-size basement should be on Clean Sweep or some other cleaning show.  How do I stop enabling him from being home all day without truly following through on a job hunt?  The kids will both be at day camp all day 5 days/week for the next 6 weeks of summer.  Hubby is an ENTP on the Myers-Briggs and does not respond well to ultimatums, deadlines, or consequences - he can be spiteful if something does not seem to be to his benefit, or his idea.  I understand I have made it "easy" for him to continue as-is... but how do I break this cycle that his brain will not allow him to break?  I have told him bluntly but calmly that it is important to have the house out of my father's name and out of his stack of bills by the end of the year.  I am concerned my ADD hubby is living in the "now" moment and will worry about the "not now" moment of being on the street or in a very small apt only when that is the "now" -- instead of helping to prevent that.
