The inspectors also used an infrared camera which allows to detect cooler/warmer temperatures behind walls and hard to get areas.  

Perhaps a private detective can help. 

If there was any harmful  mold detected I would immediately remediate.The safety and well being of my clients is important to me - and even more importantly:  it is the Right Thing to do.And also, a standard measure in Law is defined as:  What a reasonable man would have, or should have done.  

As mentioned in another post a lot of these cameras have motion detection and sound + microphones, and they can be configured to only record when motion or sound is detected.

The value is extensive....The speakers are experts from the community, such as the Fire Marshall, Community Police Officers, Landlord-Tenant Lawyers, Re-Finance Lenders, Health Department, American Red Cross Disaster Preparedness, County Drug Task Force Detective, Restoration Companies, City Code Compliance, Representative from the Mayors Office, Council for the Homeless Director, Public Utility District, Building Maintenance experts, Appliance Repair experts, Tax experts, HUD/Fair Housing experts, Legislative updates from those actively involved, and many more.  

That will go the admins who can see what's going on.PM bans take place automatically by the PM spam detection system.  

Bed bug sniffing dogs are useful, especially in early detection, but if three of the units are at a level that could be labeled "infestation" I would say it's likely that you need to get every unit treated even if the tenants aren't complaining.  

You will learn how to detect and find out the level of motivation by asking questions.For example.How soon do you want to sell?

(For those reading this who have interest, there is also an issue with property insurance in this alternative buying process, its said that the sellers insurance should be maintained through closing and beyond until you've exited the property so as not to kick in some detection by the lender.

My neighbor is a retired detective and when he's bored he likes to rip on management for petty issues like highschool/college trespassers at our pool, but warns that they have a deep relationship everywhere in the city.My rent slowy inches up by about $20 a year.
