Different methods work for different people.

I am really really wanting to dive in already and get my first Buy and Hold under my belt and use the BRRRR method like brandon always talks about!

The part of the contract that threw me off was this:"Owner hereby employs  XYZ PROPERTY MANAGEMENT (name changed for propriety's sake), as his exclusive agent for the rental and management of Property.  

So whats the best method to keep records in order to be prepared (separate accounts) for next tax year?

If you are self-employed, then there is even a better option available: truly self-directed Solo 401k, which does not require a custodian and nor the LLC to get the checkbook control.

This method eliminates the competition at the tax sale, be pro-active.Tax sale certificate purchasing is a passive method of investing, for me, I'm impatient, I don't want to wait the prescribed period of time to get paid interest on my investment (too old to wait for that).I would rather deal directly with the property owner to attempt to solve the problem they are having; no money for the taxes.There are times when if you are pro-active, visiting tax sale properties, searching for the owners, that you may find a really great deal.

I've been using the 65 percent method.

Sometimes people have a sad story (I'm sure at time some are true and some are not) but unless they have a proven good credit rating and good employment, they will not rent a house from me.  

I'm now looking to get involved more deeply in the investing side -  through buying and holding, and at some point flipping - focusing on helping those who may not be able to purchase a home through traditional methods still realize the dream of home ownership.  

@David HuynhI am surprised to hear that you found such great deals using just those methods, that's great.
