Business opportunity--offer a bookkeeping service to these guys.

But this would significantly complicate our bookkeeping.2) I want to keep closings in and out of the deal as inexpensive, simple and quick as possible.

Explain that multiple payments leads to more accounting and bookkeeping costs and collection procedures and throws everything off.

I am thinking 8 plex or more new entity would be good... please share your thoughts.Also, more entities would be annual fees, book keeping expenses, accounting and IRS filing accountant expenses etc.

I get excellent bookkeeping from my management company. 

This is not only to track my personal results for a better bookkeeping, it's for all those who may be stuck.

I can also see us hiring a PT bookkeeper, a FT rehab manager and eventually a FT acquisitions manager (but I just have too much fun doing that now I hate to give it up yet :) ).So to answer that questions, a comfortable goal would be to have 250 units in 3 years, a lofty goal would be to have 400 units.  

Or do they just handle the day to day property management (collecting rents, maintenance requests, etc) and leave the accounting/bookkeeping up to the owner/client?

Also, if you are going to be consistent in the flipping you also might want to consider a professional bookkeeping service as well to assure tight paperwork being presented to your CPA Advisor.

I know they mentioned they offer CPA services, tax-strategy and filing, and business formation consulting, but forgot to ask about bookkeeping.
