It is certainly possible to find a home that fits those requirements. The issue of course is price and location. I would recommend working a Realtor in the Tampa area to learn what locations might work best for your lifestyle and that of your parents. I have worked with my "out of town" buyers and I pride myself on finding the hard to locate homes.
Please review my profile on Trulia and send me a message or email me directly at THOYT@prutropical.com I would be happy to answer your questions and guide you to the area you are looking for.
No pressure, just help.
