I am single, too, and almost an empty nester. Without knowing your specific needs, I will just let you know a few areas I like for myself, and maybe they might appeal to you, too. Mission Viejo has some wonderful neighborhoods with a variety of products from smaller single level detached homes to terrific lake view condos in an upscale guard-gated community with its own private beach. Dana Point has some terrific attached homes that are easy maintenance, beach close and close to shopping. Laguna Niguel, like Mission Viejo, has some lovely established neighborhoods of single level homes, many that have been updated and remodeled, as well as some terrific easy-care attached homes in neighborhoods like Marina Hills that have fabulous community amenities. If I were to choose for myself, I would most likely choose a smaller single level detached home with a view in Laguna Niguel. You can see you have a lot of options. Once you check out a few communities for yourself, you might have a better idea of what feels right for you and what fits your budget.
