The worst part is I have a buyer (the current tenant) who can't find a loan!

If borrowing funds form a third-party would cost more than that may be a good option.

I also seek to add value to investors by enabling them to find and invest in great cash flow properties, while maximizing their time, as well as their profitable revenue.By joining BiggerPockets, my goal is to establish a network of professionals who can aid in my growth within the real estate realm, while also finding ways that I am able to add value to those within BiggerPockets' network who may have a need for any opportunity that I may have available. 

I've started the conversation about opening a solo 401K with some professionals. 

All I truly want to do is learn from others, meet owners and investors to grow my business and theirs, share and transfer the knowledge, and be the very best professional I can be.  

There are lots of experienced investors and professionals here to answer any questions you have.

Another advantage of having the legal entity is that it would look professional on a business card.  

Be pleasant and professional as if you were renting to them for the first time (you are).

This doesn't have to mean $, but what can building a relationship do to help both parties have more success. 

I've received a request to provide professional pest control service from tenant to help eliminate pest issue at the rental property.
