That's a difference of ~$60/month, or ~$720/year. Actual costs vary based on your Medicare plan, supplements, and health needs.
Can I afford to retire in Dallas on a $50,000 annual income?
On a $50,000/year ($4,167/month) retirement income in Dallas, rent alone would consume approximately 36% of your budget (1BR rent ~$1,500/mo) and healthcare another ~12%. That leaves roughly 52% (~$2,167/mo) for groceries, transportation, and other expenses. This is tight — a studio apartment or lower-cost neighborhood would help.
