I currently live in TN and I'm looking to buy a home in St. Petersburg Florida. Many homes in the area where I'm looking to buy were built in the 50's and on a slab. My concerns are galvanized water lines, cast iron drain lines, and anything else that could be an expensive repair. I'm not familiar with 1950's building techniques in this area and have I never owned a house on a slab. Any advice would be greatly appreciated. Thanks in advance!
