I figure I'll be putting out $2000/month all told, which means I'll be hemorrhaging money for a month or two, until I can get a the rehab finished and get tenants into the place and shift the burden of the payments to their rents.

Shifting soil of the Lowcountry.  

No, it's interest only unless the draws and work is complete, then it automatically converts to a 20 year amort commercial loan, resetting every 5 years.10.

They link directly to the tenants checking account and deduct rent automatically on whatever date you agree upon with your tenant.

For our other business that we use, I use Intuit (they run Quickbooks) for my credit card processing and I am able to choose a day weekly, monthly, etc for the charge I input to be automatically charged every time.

Most of my communication with them is through automatic systems (we have backed software for showings) and for offers (there is a backend system for offers) then depending on the listing, the bank responds directly to the contract and once it gets accepted, its all through the lawyers.  

The state automatically creates a generic operating agreement that you can use for the basics such as getting a business checking account.  

I haven't made any actual money as all the interest I receive from Notes is automatically re-invested into more notes. 

You can draw each wall manually or simply take pictures with your phone or tablet of each corner and it will draw the walls automatically.

They are being greedy and shifting their burden to you.
