Hi Tristam, I unfortunately can't offer any commercial insurers as for you but would like to comment on the loss...I'm not sure if Carrier denied this claim entirely ; if they stole wiring that would be considered Theft however I personally would consider the damages caused to the property Vandalism; in order to remove the wiring they had to gain access to the wiring and that would have probably damaged the sheetrock wall, damaged/scratched the paint, debris on carpeting (maybe metal shavings from wiring in carpet) and possibly even caused damage to the front door to the home to gain access.  

The current lease states the landlord is responsible for water, sewers, and garbage.   

Oh, and I should mention that water is on a master meter, if that makes a difference...

. - thats fix and flipBRRRRbuying property for $400k, ARV $700K, will try to save in renovation but will still come out to about $140keach 3 bedroom apartment in area is going for $2,300/month (confirmed with rentometer and local listings) Taxes are $5,300/yearso what I did was $2,300/month each unit = $4,600/month75% of $700,000 = $524,250 at 4.25% = mortgage payment of $3,943.82/monthWhen you add water, tax, insurance, maintenance I am getting another $1,138.75/monthso in the end you negative cash flow ($482.57)I know the property is being bought at the right price, compared to location, but can that be possible where a property makes sense as fix and flip and not as BRRRR? 

The eldest daughter, 14yo, stated that the youngest had spilled some water.

Also, I have to pay for normal utilities that he would normally cover for another tenant like water and sewer which also reduced the monthly rent.

But also there are others such as damaging the unit, causing a nuisance, etc.

Aside from multiple ongoing code violations, neighbor complaints and damages, they moved in extra people/pets, tried to scam the utilities, stopped paying rent and ultimately had to be evicted. 

They do have a sump pump installed yet there was enough water damage to ruin the carpet the first time, and the brand new carpet is now under water.
