You repayment is also payroll deducted if you are still employed. 

Treat your agents well for they are your Acquistion Managers who are not on your payroll. :-)

You will look at deals in a much more sophisticated way then you ever have before. 

Maybe I have not reached that level of sophistication in my life where I find questions that people ask to tacky or offensive.

It's not quite sophisticated enough for the kind of investments we run.For monthly budgets, it's gold.

Most of these larger businesses have a separate payroll department that sends out checks once a month to all their vendors.  

The hard part is setting up all that needs to be set up with an S-Corp (accountable plan, salary analytics, payroll, Corp minutes, etc).Likely, the best way to go about doing this is for you and your partner to each set up personal S-Corps that then take over your ownership stakes in your LLC.

Say you issue 5k, and he spends 4k on week 1, you then have to issue him 4,800 (4k + 800 GC fee for example) before week 2 starts, assuming you get all receipts, payroll reports, and an invoice.

Opportunities are less likely to present themselves.A sophisticated investor is selling you this property instead of holding onto it themselves for rental purposes.  

I hope to ask you more complicated/sophisticated wholesaling questions later on!
