I also practice as a Realtor because I enjoy it and it is extra income.So as an investor, your options are to get your RE license and have access to a lot of tools and do the research yourself (therefore you're paying with time, energy and a little money) or you work with a great realtor/investor in the specific market you're looking into.

Before you spend any more energy or resources on this endeavor explain the precise fear that has you wanting to transfer this property to an LLC.

Should I just bite the bullet and hire a bookkeeper? 

These borrowers typically don't need our help brokering bank & credit union loans, unless they don't have the time / energy / desire to do it themselves (or again - are required to use a broker by Freddie Mac, Fannie Mae, a correspondent life company, debt fund, or specific bank / credit union). 

Now, one month later, I’m called to face this situation.My energy level was low.

One buyer could take up a lot of your time and energy and there is no guarantee they'll stick with the deal.

A purchase agreement is a waste of time and energy and complicates the issue for Harry Homeowner.This is not a beginner strategy as there are federal laws concerning approaching debtors who have been given a notice of foreclosure.

Move on from "tire kickers" - deals that waste time and energy!!! 

It takes a lot of energy to sue someone.

Or, from a business perspective, much better to use that time and energy to create a STR management business instead of arbitraging.
