Do you have any visuals?

I have posted a video helping illustrate the situation and to provide a visual.

All depends on the property manager and the relationship dynamic you set with them.

If they don't allow the wall to be opened up the air inspection will still help show if there is are mold spores present if they do it gives you laboratory test results to go with the visual inspection report.

I am a visual learner.

I'm not sure if that comes with any pictures or anything but at least with pictures you'd have a visual to know the current position of what you are dealing with. 

From the visual, it appears to be an REO (field service notice in window) and it appears that maybe a DIY rehab/addition based on the missing outlet at 6' on the far wall?

As you get paid more yield  lets say a 10 percent cap rate now lets visualize the risk. - TENANTS --- A DOWN MARKET --- EXPENSIVE REPAIRS --- A HURRICANE ETC --- A NEIGHBORHOOD THAT TURNS WRONG.THATS A FEW OF THEM of course there are more. thats why you are getting 10 percent on that cap rate.

And you can see this same dynamic with some hard money brokers.  

An inexpensive termite inspection is simply a visual inspection of the readily accessible areas of a home for evidence of wood-destroying insects.
