If you move to Florida, I think the best way to do it is the way you're doing it, i.e. have your company move you and your family with the same salary.
I don't know how much cheaper it is to live here especially in recent years but, the life style is much better. The weather is the big issue here. Almost everyday is a sunny day and that does effect your emotional state.

This past week end me and my family were in West Orange N.J. attending my nephew's wedding, at the Manor, you probably know it. I played there a few times about 25 years ago.....anyway, we came into Newark Airport.....what can I say. I forgot how congested that area is and part of the weekend was DREARY!

The winters down here are absolutey wonderful. After you've lived here 3 0r 4 years that understanding really starts to sink in. That understanding doesn't sink in if you only come down a week or a month at a time in the winter. I do not miss the cold weather at all.

I know you have a tough decision to make considering your new home, your daughter and your commute to the city. Maybe what I've said here will help you make a decision.

Good luck.
