Newest rental home subdivision?

My family lives on the beach in Tampa Bay area, and we need to escape for a while because the red tide is making us very uncomfortable. I want to rent a house, and I'd like it to be as new as possible. We have a lot of allergies to pets, dust, and all kinds of other things (which is why the red tide is bothering us so much in the first place). I need to get the cleanest possible house so that our lungs can have a chance to breathe some really clean air for about a week before I have to come home for my kids to start school. Location of the house isn't that important since we won't be going to any theme parks or anything. We have a red tide-caused cough and have to stay away from people because all coughs look suspicious these days. I just need a nice, clean house with its own pool. Any recommendations?
