This question has at least 2 major facets:   1) you personally own the property (or maybe through an LLC)  and 2)  Your 401k owns the property being rented.   

Welcome welcome, I recommend joining up with some local rest estate groups to network with in person and Facebook groups for investors, buy/sell, contractors, etc. to just be in the mix and see who is out there making deals and opportunities.

As that will at least help folks that you reach out to know that you are a real person, with a picture and professional bio.

Merely my personal opinion, no.

I don't know your personal situation, goals and motivation. 

The bank/lender who is selling wants the proof of funds as a bank statement with the exact name of the person on the contract.

I think the privacy is high on my personal priority list as well, as i may have been going overboard by researching soundproofing solutions between walls and am actually in the process of adding another layer of drywall.

I am also getting leads where the person is saying they prefer to pay by card. 

What site or course do you recommend to start the Maryland Real estate sales person journey?

Since you are just graduating college you may already realize that it's not what you know, but who you know (as a personal note, I had college friends that were barely passing their classes however they ended up with really good paying jobs due to "who they knew").
