At some point in their selfish little lives, your kids wanted something expensive. A horse. A pair of sneakers. A new car. A college education. You, being a sane parent, said something like, "Fine. Earn the money and we'll talk." Or, still being a sane parent, you said, "A horse? Are you nuts?" In either case, your kids probably burst into tears and called you a cheapskate. This is your chance to indulge in those penny-pinching ways without anyone blinking an eye.
If you're on a fixed income (and really, who isn't?), there are low- or limited-income apartments out there that will allow you to live comfortably and still treat yourself to the occasional decaf latte. The trick is this: There are more people wanting or requiring a rent-controlled senior apartment than there are rent-controlled senior apartments available. As Americans live longer and longer, there are more of us stretching those dollars farther and farther.
Again, you're going to have to think like a teenager trying to get into college. Do your research and apply for one of those coveted apartment slots as far in advance as you can. No entrance essay required -- usually.
