If so, are you concerned about Spain's tax system on worldwide items?

Unless the item is a total fabrication.  

Plumbing, windows, driveway, etc - all big ticket items. 

Roads, water, sewer, gas, electric, etc..I'm also here for any discussion on any other items that might be of note, trying to learn as much as possible on this front.

All 3 of those big ticket items that you're looking for can be found in the Memphis , TN market.

The itemized damage estimate that my insurance provided me lists an Actual Cash Value that is 15% higher than my Dwelling A Coverage. 

Birmingham’s market is diverse, with various areas offering different levels of potential and risk, so getting boots on the ground can be one of the best investments you make in terms of time and money.I’d be happy to connect and share more about what I’ve learned from my experience managing properties in this market. 

They won't learn those items until they actually do deals. 

An example was a line item for alimony (I am single and have never been married).

So using your words "Lockup" the property but make sure your offer includes due diligence items to protect yourself.
