I owned a single-family home rental in the Denver area for a few years and then sold it, but it got me hooked on real-estate investing and I am interested in getting involved again.I'm a stay-at-home mom with 2 young kids and I do a little bookkeeping on the side.  

:As far as keeping assets separated, isn't the main idea to keep completely separate bookkeeping and not mix personal finances with business finances?

Payroll, bookkeeping, etc can mostly be done remotely.Here is a great list of questions to ask a potential accountant:http://www.biggerpockets.com/forums/51/topics/70447-questions-to-ask-a-cpaAlso check out the www.NAEA.org page in your search.

I am trying to better myself on Quickbooks Online for bookkeeping etc.

Feel free to reach out to me whenever (especially if it's accounting/bookkeeping-related)!

I am looking for a company to handle all bookkeeping and accounting for our property management company 

If you give the settlement statement to your tax accountant or a knowledgable bookkeeper, they can book them for you and explain each individually.

Plus, you're dealing with added time doing your own research, bookkeeping/accounting, taxes, etc. 

Bookkeeping tends to become increasingly burdensome as your portfolio grows.

My next goal is to find an admin who can help with leasing, calls, bookkeeping, and leasing activities (most of which can be remote).
