Our home is very large so the wife & I can find some quiet time apart if we need to or we'll head to the Lakehouse to chill in complete isolation.

Also is this foreshadowing for bigger problems in a house or it is just an isolated incident?

I highly doubt either of these have even a micron of validity.The parties with a financial interest in you buying into this will site isolated instances of great success, never mentioned the all more frequent instances of total failure.So at the end of the day Eddie Speed has collected $30,000 per person for his NPN mentoring program, Granite has made 50 to 100% profit on their inventory, private middlemen have turned a $2500 investment in a note into $16,000,  and my sister in law who purchased 5 NPNs over three years ago and has spend large amounts on attorneys, taxes, and brokers has yet to see a penny in return.To paraphrase, if you don't know who the sucker is in any ultra high profit promise situation, it's you.

His target market though is rural  lock and leave cabins.. if you have ever owned property back in the woods or a cabin that is kind of isolated many times they get broken into.. this form of housing is literally bullet proof lock and leave.I was just at a RE conference this week in san Deigo and one of the guys in Storage business was talking about using these for storage factilitys.. you can stack them 5 high then build a facade around them.. one company has got that working..

But that is the way to test; you also will want to close shut off valves as you go along to isolate sections once you know their status (a section leaks badly, stop testing it).And you will use much lower pressures if you are checking gas lines for leaks. 

Lots of older return air vents can end up in small hallways, etc where all the doors end up closed and isolating the vent itself.

Compared to leveraged real estate, this will of course be likely to underperform, especially if you can bring economies to the investment like managing the property yourself, etc.With regards to overall return, I believe that the 401(k) can no longer be looked at in isolation within a few unattractive (by our standards) publicly available funds.

I have also recently learned to isolate different aspects of my inspection process.

Recently, I had a similar issue with unresponsiveness (this is not an isolated incident).
