I am very familiar with the area that you have described in Deerfield Beach (and southern Boca Raton).
There are very few duplex homes available in those neighborhoods. 2/3 bedroom Condos can be purchased from $200,000 to several million$$.
Some considerations for Condo complex's are type of security (full time guard, gated), number of parking spaces (assigned, covered, community garage, etc.), pets allowed, monthly maintenence fees, rentals allowed, elevator, pools, community activities, etc.
Please contact me with your "wish list" and approximate purchase price and I will get busy and help you find the "prefect home".
