Copper pipes got stolen.... 

In fact the listing agent told me that the permits were actually stolen from the property.

I'll add a reminder that Bitcoin has lost 62% of it's value in the last 6 months. 

We don't spend a lot of time worrying about theft but over the years we've had some tools and materials stolen.

If you find yourself in need of expertise in "commercial lending that we're going to shove into residential because terms/conditions/rates are way better," where guidelines trump logic, let me know how I can help.I've stolen business from folks on your side, for example, by having them put the 5th unit's oven/fridge/sink hook-ups under sheetrock and calling it a residential 4-unit. muahahahaha. 

The 220 plugs stolen along with my AC unit.

If the walls are wrecked and the wiring is even partially stolen...move on to something else....if they neighborhood stole from it once...it will happen again either during your rehab or if it ever goes vacant.  

If you are too dogmatic about the 2% rule it can lead you into some war zones that look good on paper, but don't turn out that way when you're tenants don't pay rent and then wreck the property and then it gets broken into and all the copper gets stolen... ask me how I know these things...

Water pipes are cheap and easy to fix (install PEX so they won't be stolen again). 

However, if you reported your license to the police as lost or stolen and you have proof that of such, you may be able to send that proof to the collection agency/municipality that is sending these letters.
