Yes, I'm familiar with Margate - I grew up in a house on the edge of Melrose Park near Plantation, in the SW area of Ft. Lauderdale, near Broward Blvd. My husband's parents lived in Melrose Park, a little area right off Broward Blvd and near State Rd 7. Our house was brand new in 1960 and we found out our builder had a little more work to do when Donna hit. I walked into my room and had water up to my ankles so as soon as the storm was over, the builder had to come out and fix it.
Speaking of 60's houses, ours had terrazo floors which I used to hate but have since remembered more fondly. I would take those over carpet any day. I hear that you can't get them anymore. I'm glad your house looks better now, the last time I saw my old house it was kind of sad. It was right on 31st Ave which has since been renamed and has not aged well.
