My sister and BIL had water leaks in the home near Orlando. They had already had 1 or 2 fixed by tearing up the foundation. When they kept occurring, they gave up and had lines run over into the attic as a "permanent" fix.

Our new home in Chandler AZ was plumbed (when built) with lines in the attic. In the summer, the problem was getting cold water to the kitchen. They water would come out VERY HOT, you'd have to run it for a minute or two for it to cool off.

You can check into a water recirculator pump as part of the re-plumb if you are concerned about delays in getting hot water to distant fixtures from the heater. Our house has one and we have zero issues with almost instant hot water to any fixture - and our house is 2 story (and basement) with >6500 sq ft. Our water heaters are in the basement - two plumbed in series with recirculator pump on the output of the 2nd.
