The short answer is absolutely. Like any town in South Florida - or anywhere else for that matter, whether it be Boyton Beach, Delray or Coral Springs, you should check different neighborhoods of the town to see where you feel the most at home for your retirement. Delray has a beautiful downtown area, quaint shops, family owned restaurants and terrific entertainment. It is as safe as any other South FL town, and to find an area around there to live, I would ask the local Realtor to email you some homes in your price range. The homes further west of downtown should be newer than the ones closer to the coastline due to the natural expansion of that area.
Let me know if I can help you further.
Best of Luck,
