Some of us didn't have a choice. I've been severely disabled since before I was an adult, and chose van dwelling as a risky escape from intolerable abuse and neglect. $733/month is the most I've ever "made" in my entire life. It is difficult to live off of and very difficult to save with. I have no shame entering this lifestyle without savings; it is the hand I was dealt and I played it as best anyone could have.
The question of making payment is a good one, but it's never been a problem for me. First, I rarely carry a balance, which means on payday the first thing I do is pay off credit. This over a month before its actually due, since I also pay as much off throughout the month as I can. So, if I have a bad month, there is some cushion.
I have super bad memory, so I've set up autopay as 'safety nets'. The accounts I rarely use are set up to pay the balance in full, and the main account is set up to autopay minimum balance. I set this all up to occur as early in the month as possible, when there would be the most money in my account. I don't like to rely on autopay for credit balance, so this is just my backup system. Usually I'm paying off a balance long before I get the actual statement for it....and when I can't, I have time to tighten down my budget. Even then if I couldn't pay in full I'd still definitely be able to make minimum payment.
In short, I don't worry about it anymore.
Sorry to hear about your disability bitty you'll be in my prayers!! i know it's hard being on disability on what they give you to live on in short it sucks!! not calling anyone stupid but for me it's a personal choice not being in debt while being on the road as living on the road can be exspensive also. but it all comes down to how you manage your money!! if your a spend thrifty forget it someone won't last on the road one break down can cost em LOL. i agree with your system also about rarely carrying a balance and paying em off early!!
