Ohiotennis,
Out of the five towns you mentioned i really like Weston.But, you should also include Cooper City.Located just north of Pembroke Pines and just South of Weston.Take Miramar off your list.The rest of the towns are good in certain areas.But, all of Weston and Cooper city are good towns for families.
Great public schools in Weston And Cooper City.
If you're looking for Catholic schools you need to check St.Thomas and Chaminade maddonna.St.Thomas is located in Ft.Lauderdale and Chaminade is located in Hollywood ane both are excellent schools.My ex-girlfriend is a graduate of Chaminade and my best friends Dad is the head Baseball coach at Chaminade.
A handy County website is
WWW.bcpa.net. it is the county tax collectors office and will help you when investigating for a new home.
For $400,000 to $500,000 you should find a suitable home. Prices in this area have gone thru the roof in the last few years.Insurance is a killer along with property tax.Just a heads up.
I hope i answered some of your questions.If you have anymore just let me know.
