I have been a Realtor in Naples for 24 years and will be happy to help you. My email address is hugnelson@comcast .net, phone 239-641-7692. Across Mercato you have Naples Park with older homes under $250,000. Pelican Ridge Villas under that price too. Let me know if I can help you.
Our office is across the street from Mercato so I know the area and there are a few property options available to you. In order to focus only on properties that meet your needs though, there are two important questions that need answering so your time isn't wasted looking through unsuitable properties. How close do you need to be to Mercato? and what property type(s) are you willing to consider?
If you can clarify these two questions, I would email you only properties that meet your needs and you could decide if they are suitable or not.
