It also gives you the opportunity to be creative on how you want to vest/take Title (LLC vs Individual name). 

I am open to learning from experienced individuals, whether through phone calls or Zoom meetings, to deepen my knowledge in this area.

I was told the investor pays to lease out the entire flat for 6-12 months and then sub-leases the individual rooms for a profit.

The individual agents/teams within the brokerage are the ones that set out to establish a niche to work with investors.If you're looking for a broker primarily focused on working with investors, you may want to speak with commercial brokers and agents.

A 14-50r plug was always the preferred method, especially before the world woke  up and switched to the Tesla charging standard.

I actually prefer if they were already gutted (less work and expensive for me). 

That definitely won't help when it comes to trying to purchase a new property with a conventional investment loan in terms of DTI.But yes, in general with every property you purchase with a conventional loan, it makes it harder to purchase another property with a conventional loan given the DTI restraints UNLESS you exponentially increase your income (preferably W2).

I'm looking to connect with other individuals who are putting their money to work via short term lends.

SFD vs condo vs 2-4 unit, hold vs flip, turnkey vs rehab, passive vs active...it really comes down to each individual property/opportunity, what your goals with the property are, and if the numbers make sense or not.Best of luck!

Not only would you benefit from having a partner's input on the deal, but you would also have an experienced individual to work alongside with as you navigate the project.It's also important to make sure you have identified your "team" ie; contractors / realtors / lenders / insurance agents / title company / etc.
