No I have never had any pictures or decorations stolen.

Gold can be stolen, so; it is a risky investment and one that puts gold owners' lives in danger by making them vulnerable to loot and attack.The stock market is also unpredictable.

@Eldridge Stroman Talk with your insurance agent, but you'll probably want vacant property coverage and builder's risk.While you're rehabbing, takes steps to guard against having tools and building materials stolen. 

One last thing that I’d recommend looking into is Bitcoin.

To briefly touch on some important points, however …If you’re worried about a downturn, it’s not at all clear that precious metals and cryptocurrencies are uncorrelated assets or negatively correlated to the stock market, meaning in the event of a recession one should expect them to retain value (in fact, recent evidence suggests the potential for an opposite correlation of both Bitcoin and gold).If you’re worried about inflation, real estate is as good or better hedge than just about anything besides stocks.If you’re focused on returns, RE returns easily beat precious metals pretty much any way you slice it.

I was at a closing in ATL a few years back  ( attorneys office in a A class office park) and commented on how come its so hot in here.He said their condensers were stolen the night before :)  its really quite the sport in many areas of the mid west deep south. 

You have bigger issues to worry about if your identity was stolen.

One "student" has a side gig: mining bitcoin - lookup what open pit mining rigs look like on Amazon- ten fans, thousand wires.Or they have a grow in closet or in the bathroom -black or silver plastic with zippers and lots of vents and fans.Bill it to tenants they all know who is doing the power grab.

. #1, is it worth having insurance cover the loss for the tools that were stolen?

We often have stolen vehicles abandoned pretty much everywhere.
