Those with option-ARM mortgages ratcheting up to a higher APR in October, take note: A well-polished piece of advice for home owners is that mortgage payments, including principal, interest, insurance, and taxes, should not be more than 28 percent of your gross monthly income, according to the August issue of the USAA member magazine. Individual situations may vary, but the basic idea is not get more house than you can afford. Around 28% gives you enough to take care of day-to-day living expenses and food and gas and going to see Transformers and whatnot.
