I think your agent is making a good suggestion.You can go to about $200 per square foot. That will up the potential of the 50% rider also, putting you around $300 per sqft.I believe you also have coverage for demolition and clean-up before rebuilding. That should do very well for now,including handling any code upgrades, not forgetting that 10%.There is plenty of coverage to allocate toward code upgrades even if 10% wouldn’t cover it otherwise.
If you go this route, verify that the rider stays intact. I recently did the same thing with Allstate and still have all the coverages mentioned here, including the rider at 50%.
