I asked the builder's rep the same question when we had our walk through. He said they usually install them the same place water softeners are installed. In our designer it's in the garage where your water shut off valve is located. You have to use a couple of elbows because the pipes are in the wall. You need route them out of the wall so you can have access to the filter. They're plastic pipes so it doesn't look too difficult.
We're snowbirds too so I'll take care of this when we return to TV in the fall.
The reason for the whole house filter is the same reason I installed one up north. The water just tastes nasty. Up here it's chlorine. I don't know what it is in TV but I'm hoping the filter removes whatever is causing the off taste. A softener might work too but a whole house filter is way less expensive and easy to maintain.
