There they are seeing both a great job market, a number of large employers moving in, and are still in the top ten of population growth nationwide. 

The newest outdoor is still advertising 1st month free as they haven't filled up, and I spoke with the climate controlled owner/builder yesterday (he's a pretty big REI in the area), and he made it sound like he hadn't leased a single climate controlled unit since they opened a few weeks ago.I recently purchased a 140x45 warehouse with low ceilings and had debated doing self storage, but my market seems very saturated.

We are currently buying blend and extends with tenants having low years remaining on the guaranteed primary lease term.Closed on one last month at 11 cap rate.

I certainly know that future years the expenses won't remain that low, but wouldn't that be a reality on a property that has a lot of recent improvements?  

The median home price is also very low nationwide which creates a low barrier to entry.

Low or no down, seller financing and low or no interest with a balloon payment later is the holy grail (location, building condition, market also matter but it sounds like you have all that).

They used lasers to find the low spots and used "push piers" to lift those areas. 

@Kenneth Joseph PerfidoFrom my experience, you’re in a great position with your Newport property, strong cash flow, and a low 2.8% interest rate.

Would a low enough sales price make all of my concerns go away?

Ebooks, podcasts like @Bonnie Low suggested and start running numbers on every deal you see until you know how it all works.
