I've heard of people walking away from the negotiation table with cash from seller financing deals...

What type of relationship do you seek and what do you think you both bring to the table?

The $8000 I brought to the table was used for insurance escrow and buying my interest rate down to 2.5%.

In general, but not a definite truth, the buyer who has 20% down will have a better pull-through to get to the closing table.  

From the lender's point of view, they are taking all of the financial risk in advancing 100% of the total costs.As a general paradigm, you should be prepared to bring a certain amount of the project costs to the table (which will vary somewhat depending on your creditworthiness as a borrower, and also the quality of the deal), and then use a lender to leverage the capital you can bring to bear.Hope this helps,Michael

My guy is good, but he's also too busy for his own good, and thus leaving money on the table.

More than once I have gone straight from the closing table to the bank to initiate a refi that same day.For now you're probably better off waiting out the 6 months and taking advantage of the better terms you're getting but at some point you will start buying properties using your LLC and embrace the world of commercial loans. 

is 100k enough to bring to the table for a new investor into a deal?

Keep it about the seller and the benefits do you bring to the table.
