Once the legalities are straightened out, a nice way to dispose of their items is to contact your local Habitat for Humanity and ask if they have a ReStore.I'm on the Board of Directors for the Habitat here in Waterville, Maine and our ReStore is a significant contributor to our funds - and that helps us to build more homes.ReStore accepts donations of all sorts of household items from furniture to tools to sets of dishes to cabinets and plumbing fixtures. 

On the 6th day since incident, a restoration company (Owner - myself present) assessed the water damage and advised  moisture still present in ceiling cavity and it cannot dry by itself.

Mesa definitely needs a lot of it's multi family units restored to value. 

The realtor mentioned that it was set by some homeless people and maybe contained to a one-room, etc.To be sure of the damage, I'm going to get a walk-through of the property by a local Fire restoration company and my contractor.

I would ALWAYS suggest including the local police non emergency line, that comes in handy often and prevents unnecessary 911 calls.Even if utilities are paid by you, it's not a bad idea to include the numbers of your eclectic, gas, and water providers- even if their names aren't on accounts, they can find out when power will be restored quickly (saving you or PM a three am call maybe)As far as gifts go and actual items, things that would apply to most everyone in being useful seem like a good idea (an not offensive in any way like scented candles - those items are not across the board items) but things like nice dish towels, simple kitchen tools/gadgets, a welcome mat, fridge notepads and nice pens, etc. 

You get what you pay for,  several restore outlets across the nation. 

It simplifies tax administration and lowers compliance burden.BAR stands for "Betterment, Adaptation, Restoration" under the tangible property regs. 

One is a window treatment supplier the other is a hobbyist who does wood crafts and is restoring his small sailboat, I can't find anybody to insure the Building (I can get liability insurance but not property).

Additionally concerning is that the home restoration is expected to take at least 6 months, potentially accruing tens of thousands more in storage costs.Is this routine practice in the industry?

I flip fire-damaged properties and own a fire damage restoration company.
