:)I am sure this is a solvable issue with some work.

May I kindly request your help should you have a model I can use?

And no help.

Is this a new build?  

I would think your insurance agent might have access to some historical information for a specific area as they would want to examine this closely for their underwriting.

Is this normal?

This is correct.

Your taxes are none of the ex wife's business and this would seem to address your concerns.I would also put her on notice that future requests for financial discovery will be two-way and if a discrepancy is seen in the other direction you will seek support from her.

Any help or tips/tricks would be greatly appreciated.Thanks!

I could say a particular town or area, but if there aren't any, many properties for sale that doesn't help.
