You could also look into DSTs for 1031 eligible fractional passive ownership of institutional properties. 

Beyond that, I am not sure if consolidating all banking to one financial institution is wise either.

There have been a couple software companies in the past but they have moved more towards institutional investor focused than the small investor.

Out of state and institutionally funded can be tough to close at times. 

I think this is the gift and the curse of a still emerging asset class (short term rentals) - as it becomes more "institutional" i.e. more like commercial real estate with more sophisticated buyers then financials and systems for this will likely become more streamlined and stable, but we are still in a place where the buyer pools are more newish investors or typically residential basic investors, so not has experienced or sophisticated evaluating investments based on a detailed financial analysis like more seasoned commercial investors likely would.anyways, just a guess on what might be going on here

The challenge when renting directly to the government is that they expect below market rents.From what I've read in the past, most institutional investors look at these leases like US Treasury Bonds (extremely low risk) and expect a similar rate of return as bonds.Keep this in mind while you try to negotiate a rent increase.

In the same way, so many churches want to guilt you into giving directly to their institution (mostly because they have initiatives they feel are important). 

Any recommendations for institutions that can extend a line of credit backed by a whole life policy?  

Hi, this is definitely a great question for a lender/ professional financial institution advisor they will steer you in the right direction.

But no lending institution is going to give you 100%.
