First of all, the insurance-contractor circle is ridiculous. People will figure out what the max extent of your insurance will pay, and charge that.
Understand that, and you understand the basic economics of every failing plan behind insurance, health or otherwise, as well as why universities are in the same category as health care insurers.
Second…if I was king for a day, and thank your personal gods that this will never happen, I would make school loans fully dismissible in bankruptcy, and make the institution that sponsored the loan responsible for the resulting subrogation.
That aside, building codes can be a beotch. After Andrew, Florida coastal building codes went nuts. A tiny 2000 sqft home was running about $40k to replace with nothing special. Anything tile related would be $60+.
Want to save money? Move away from the coast. Duh.
