Death is obviously difficult for any family, as is the following estate proceedings and such.

I am currently a property manager of various types of properties ranging from multi-family, single family and shared rooms with somewhat difficult tenants at times.

What that will allow you to do is setup a US Bank account.The fact of the matter is that traditional bank finance is difficult to obtain (especially in the early stages).

Welome to BP @David Doheny,I would say other than those things you have listed, start talking to potential clients.

I pride myself on being there for my clients 24/7 (respectfully of course, we Realtors do need our family time).My past clients have been happy with my "turn around time" when making offers and keeping the sellers agent on track and keeping the transaction on pace.

Then put the forms for buying in one folder and selling in another folder so that you can review them before going to meet a client.

Next, adding interest to an underlying loan, several issues, but your interest rate won't match the principal owing on the underlying mortgage this makes tax reporting and borrower disclosures difficult, beyond the financial scope of any small investor without a loan compliance department. 

Gaining trust in your ability to manage someone's money is paramount, and you don't appear to have a track record so it could be a difficult sell.  

My firm manages over 200 clients in nearly every time zone, so I'm used to being "on call" all the time with the CEOs that I work with.  

If you don't have the funds to advertise it will be more difficult but no immpossible.
