Is there an online platform you would recommend to help find someone?

@Sam Jiang Do not ask your accountant legal advice and don't ask an attorney accounting advice.

Legal?

If i had any questions i would call my architect and ask for advice or look online.

You also may want to require in addition to down payment from the buyer 6 months to 1 year mortgage reserve payments in advance.Do not set your interest rate below market or you could get hit with imputed interest charges on taxes.No legal advice given.

I do not have a realtor/broker license and have recently been reading that it has become harder to connect buyers and sellers without legal repercussions because of this.My question is what is the best way to connect a seller to a buyer without infringing on the legal properties that licensed realtors have dedicated to them?

What you're essentially asking for is legal advice, and for that you should seek out an attorney knowledgeable in this type of law. 

What I am trying to get all my tenants to do (and most do already) is pay online. 

No attorney can really help you as the bank has no responsibility, or perhaps even the legal ability, to negotiate anything with you.You have no recourse against the county or the courts.  

I am also a part time college professor (I share this because I heard there might be a first time home loan available for teachers as well, but I couldn't find any information online).
