Any feedback will be appreciated for the bookkeeping.

Call a few property management companies and compare them.Take a look at Google/Yelp reviews (sometimes bad reviews come from angry tenants.)Ask questions about finding/screening tenants, repairs, bookkeeping, etc.Ask how much experience they have.Finally, be prepared to switch after you hire one, if you don't like the company.

I'm looking for someone in Riverside County, San Diego County or Orange County that is savvy with taxes, bookkeeping and business consulting for a young investor with big dreams!

I have two different questions:(1) I'm looking for a new POS system for my income tax / bookkeeping business.

If the turnkey provider does not have a finance executive, and not a book keeper, my advice is RUN.  

@Benjamin Sklar really good bookkeeping and accounting software that ties into the property management/rental side of things (i.e. have you ever tried to use the accounting in appfolio - it is not very user friendly).

Is it eviction notices, cleaning a trashed apartment, screening tenants or just the book keeping.

That LLC should have its own bank account and bookkeeping and would be on title as the owner of the property that you purchase. 

Presumably annual income statements/tax returns get shared amongst all partners, would it also make sense for the agreement to mandate more granular bookkeeping (such as on a per-rental basis)?
