I'm on the ACA right now. Started out on Cobra, then the price went way up, so switched to ACA. My plan is pretty high because I wanted to keep my specific Dr., but I do get a subsidy. Just have to get through Sept 2018 and I will be on Medicare. Husband is older, so he is on Medicare already. Even though I pay quite a bit for health insurance, it beats working!
Right now, I'm not taking SS and letting it increase and husband is still running a business, but has subcontracted it out, so our income is OK with pulling out 4% from total stash. Just have to watch how much I pull out to keep subsidy.
