What time should I have them send a detective to take finger prints, take statement, file a report?

You will develop(or further refine) an ability to talk the RE investor language, and furthermore, will develop(or further refine) the ability to quickly detect who is sharp(or not), in regards to investors and realtors. 2.

Imagine you're a detective solving a mystery, but instead of clues, you gather information about your customers.Each customer is unique, with different needs and preferences.

I would scope the lines to check it out and then have the plumber do a smoke bomb test where they can detect where the smell is coming from, that way to get to the problem and fix for you.

Many benefits to this route in my opinion.The inspection report (typically 10-20 pages) will:- highlight condition of mechanical systems: heat, gas, hvac, electric- give you an idea of which cap ex items need attention: plumbing, foundation, roof- detect hazardous conditions: termites, mold, asbestos, etc- summarize interior and exterior condition of the property- lastly, it sets the expectation and gives reassurance to tenants that you are on top of thingsThere are even tools out there that help you estimate repair/maintenance costs based on the inspection report i.e. repairpricer.comAll the best to you!

It's time to hire a private detective 

Yes - I have 2 quote :1 for a leak detection and 1 for the access and water line re routing. 

Or is it enough to know that fentanyl is hard to detect, very small amounts kill and we have to be diligent in who we allow to stay at our STRs? 

However, going shoeless is not in the American culture and such will not be seen as you or I may understand it.I saw later, the reason is to avoid detection of the flooring not being compliant, maybe rugs will work for you.Maybe if you have a fine, as I mentioned above applied to neighbor complaints, then just inform them that walking with heavy shoes on the flooring may cause noise on the ceiling below, may be the tenants will get the idea to walk quietly, might remind tem too that floor speakers with the stereo (if people still use them as I do) will also be an issue with that flooring.Just suggesting other ways to get the message across rather than imposing on them about shoes being worn.
