We have to do safety smoke alarm testing anyway, so this is a great way to get into each room of the house. 

@Nathan G.Yes, Nathan, this is it, a landlord who got screwed by an experienced thief only because they made one mistake -- they didn't run a background check.

If you find anything alarming you can back out.

E.g. utilities, software, pest control, accounting, legal, Advertising, Alarm service, taxes, merchant fees etc.

Here's a few things you can do to mitigate this from happening: Hire a house sitter (~100 per week)Ring alarm monitoring system (~20 per month, no internet required)Plant some flowers in the front (imply occupancy)Install dummy or real security cameras (some area even cellular based for live capture)Drill the exterior doors shut As far as theft/vandalism goes, make sure you are insured correctly with a builder's risk policy that covers it. 

- Called him a thief- He tried to defend his actions.- I fired him and learned a very expensive lesson.- Hired next contractor and only paid him a small fee up front- Bought all supplies and delivered myself.- Supplies were stolen as home was not secured properly by contractor.- Work done was not that good- Fired contractor #2- Hired Contractor #3- Spent even more money to fix #2's shoddy workahhhhhhh.....completed........- Hired property manager- Heard crickets chirp for weeks- No return phone calls- Fired Property Manager- Hired Property Manager #2 - See Property Manager #1 experience- Decided to manage myself.- Advertised- Many tenant prospects would make appointment and not show up?

If you don't write anything that might alarm the buyers about the mold -- and if there is no evidence it still exists -- it probably won't be a big deal.

If they install an alarm then you will also need the alarm addendum and code.Even still since its illegal federally you run the risk of losing your house to the feds.If they dont want tosign the addendums them you need to ask them to leave.I had to consult an attorney last year when I allowed this in one of my properties.Now... the aftermath.

It occurred to me the other day after I accidentally left my phone at a restaurant that if a thief wanted to they could have access to everything in my dropbox.  

Hopefully I am wrong, but my red flag alarm is going off.
