If not PM me and I will talk you through some of it.Good luck airborne.  

They should immediately let you into the property to inspect.Mold can be airborne and on the surface.

The landlord needs to be notified asap if there is something airborne that's reacting with surfaces or causing a residue in the house.

Oh heck yeah I have a few drone shots in my listings usually with labels 

I create 360 video with drone video of the roof!

Anyway, the best way to find a buyer for a vacant parcel is to put it on the MLS, so we "whole-taled" the ones we've done, meaning we closed ourselves with our own money on the vacant lots at what we knew were a decent price, i.e. 1/3 or 1/4 of what the vacant lots around it were trading for, and then we immediately put it on the market, however in an intelligent and professional way, meaning we knew the exact details of the zoning (most listing agents are too lazy to figure that out), utility availability, drone/aerial photographs, etc. 

As long as it is moist mold is not dangerous, once it dries and becomes air born it is a problem.

Plus generally no real Chief,,,all drones,,,all scattered across the globe and know zip about the farm other than they get a check.IF you are 'creating' fractional interest of unrelated parties,,to be avoided unless YOU want to be a full time argument settlement biz. find a NEW way!!!!

Between the brawl with publisher Hachette over e-book prices, drones, and the Amazon Fire phone’s flop, losses are heading Amazon’s way."

They just hire someone inexpensively, tell them the max # and the person bids like a drone up to this number.The other states with online auctions seem to have few if any attractive properties in the online inventory.
