If vacant you need to:what is cost of dumpsters vs buying a pick up or finding some hauler to throw away all the demolition  secure and board up and add cameras, get roof bids, order roof parts, roof needs to get on the house ASAPclean out dry wall, everything fabric throw away, cut up and remove carpet, mop the studs and floor with bleach and water solution (5% bleach), inspect electrical - maybe some shorts or problems, order flooring for kitchen and baths and new kitchen cabinets (measure like you are OCD ten times), how is the sub flooring?

For example, often fire damage is water damage--they put the red stuff out with wet stuff.

Maybe low flow toilets and new low flow shower heads, LED lights, rainwater capture system and cistern to use that for landscape watering.

The insurance company paid out 8100 for the water damage and 5200 for the building that was drove into. 

They are completely separate buildings (500 ft. apart) but share water connections, entrance easements and such.

If you see signs of water damage in the basement (if there is a basement) you may change your mind. 

There was a creek in the back yard and the birthday kids played in the water and mud and tracked it all over my house. 

This is a 100+ yr old brownstone, the layout of the basement does not allow for storage cages and with the 3 boilers, water heaters, and where the utilities/sewer line etc are arranged there isn't a way to accommodate storage without blocking access to the circuit breakers, meters, or the basement's bulkhead doors.

I'm reviewing a Condo that contains HOA fees that cover things like the exterior (Roof, siding, landscaping) along with hot water heaters. 

I use propstream to skip trace but there are a lot of good ones out there.We should grab a drink or meal, I would be happy to help.
