I am, for going on 3 years now. I was renting a 3-bdrm home and decided to downsize for obvious reasons. I applied for subsidized housing and moved in with my son and his wife until I was notified that a one-bdrm apartment was available. The rent is only $344. I'm also in the HEAP program and since it's an efficiency apartment, I pay an average of $30/mo for both gas and electricity year-round. These easy-to-handle costs allow me to buy cable TV and internet. Though I have no premium channels and it isn't the fastest internet, I feel lucky that I can afford service at all. I have one phone, a cell-phone, not a smart-phone, that my son included in his friends and family plan. I keep usage under limit and don't get a phone bill. I have one small credit card that I use to buy Christmas gifts every year, limit gifts to grandchildren under age 20, and pay it off within 6 or 7 months. This way there's always credit available for vet or auto emergencies.
Took me a year to really get into the swing of things, but it's working well. The only thing I find distasteful are the rules in my state-subsidized apartment community, and not having a private yard. I'd have been happy with a 5'X8' patch of earth so I could make a hobby of growing ornamental plants and a few vegetables.
Next year I turn 65, and expect a change of income followed by a rent increase and no doubt other changes.
