This is the most realistic path to scale  for most BiggerPockets members who want to truly grow a real estate portfolio but very few reach this point. 

I have reached out for some quotes.

I would suggest reaching out to them & talking about what you want to do. 

Quote from @Stuart Udis: Unfortunately there's a ton of online content teaching novice investors that reaching XYZ number of doors equates to financial independence.

Reaching out to multiple brokers in the area and building relationships with them will probably be the most important piece.

@Scott Tennell there might be two different definitions here to the PML term.So, if you mean you are reaching out to PML that lend money all the time and have experience doing it - then they will tell you what their requirements are.  

Reach out via PM and we can exchange info, if you like.  

As you said, it's a no-brainer that if you just spend time answering questions (without an ask), more people will reach out to you.

I'd be happy to go over any loan questions you might have, so feel free to reach out anytime! 

Start reaching out to landlords, you can get all their contact info using reonomy which only cost about $100 per month to get direct owner contact points.
