A roof extending over a lot line would not be latent, as it is observable with the naked eye.

Best way to detect this is to observe them during the home inspection.

From my observation, if you don't manage your own properties, there's little to no profit.

They probably don’t want to admit the real story to themselves or their investors.My observation is MF values are down 25% to 37% from peak—I have a case study with a reliable value at the moment of peak and a semi-reliable current value estimate—the drop is 37% and this is not a distressed property. 

Greg, nice observation . . .

After some observation, we decided it was just noise - no one was watching it; they were looking at their phones. 

However, from what I’ve observed, it’s still not enough to produce meaningful cash flow.

One observation is that @David Dachtera changed his argument.

Some of the hottest areas I've observed include Temple, Kyle, and East Austin.

Mine typically do provide pictures of anything observed to be out of the norm when they arrive at the property to clean.Sorry for the confusion!
