These days, I hear there are apps that can transfer money quite easily (Venmo etc) although apparently I'm on the old end of the Millennial spectrum and thus no longer understand technology.I'm glad that you did the research to make sure this was legit.  

I am as close to 'amateur landlord' on the spectrum as is possible.

My Military Occupational Specialty (MOS) in the Army is an Electromagnetic Spectrum Manager.  

If you can't pull down a deal on a 25,000 sq. ft. factory building, don't look at such properties, if financing is harder for you on a 40K sale price, might look at 65K properties, there are deals to be had throughout the price spectrum. :)  

I was working with Lima One through a 3rd party called Spectrum Funding.

You want someone who can cover the spectrum of potential deals for you.  

Ive heard spectrum utilities also sub meters though.

Sure, we need to be aware of the extreme end of the spectrum and be prepared for it but making decisions based on worst-case scenarios isn't the best outlook on life, in general, and if you do the upfront legwork of screening your tenants properly and avoid buying properties where worst-case scenarios are more likely to occur, you will be fine the good majority of the time.

As a very experienced investor/owner of real estate I can see both ends of the spectrum and everything in between.

If you've got a very basic, utilitarian property you're at the lower end of the spectrum.
